Synbiotics Cleaning Solution
This technology is a patented synbiotics (combination of probiotics and prebiotics) cleaning solution that offers a safe and sustainable alternative to traditional cleaning products and disinfectants. When released onto the surface, the probiotics will digest and break down dirt, grime, and other unwanted substances while the prebiotics in the solution act as an additional source of nutrition for the probiotics. The resultant surface microbiome provides a continuous cleaning effect that is longer lasting than traditional cleaning chemicals and disinfectants. Often, the overuse of traditional chemicals and disinfectants results in antimicrobial resistance (AMR), allergenic reactions to the user, negative impact on the environment and short effective lifespan. With this synbiotics technology, users can overcome these limitations and achieve a long-term effective cleaning system and a natural microflora to the environment. When utilised in healthcare settings, the synbiotics cleaning solution demonstrated a higher reduction of pathogens (80% more), decreased AMR (up to 99.9%) and health-associated infections (52% lesser). The technology owner is interested in co-development projects and test-bedding opportunities with companies looking for a sustainable and long-lasting cleaning technology i.e., cleaning equipment and automation manufacturers/suppliers and cleaning service providers. This technology consists of proprietary dual action deep cleaning probiotics enzymes and specially formulated surfactants which helps to detox surfaces, break down biofilm and dirt components through a continuous cleaning effect and microscopically purifying down to the deepest pores of surfaces. Main features of this synbiotics cleaning technology include: High efficacy and able to target broad spectrum of pathogens Long-lasting and continual cleaning efficacy Safe and non-toxic Decreased AMR (up to 99.9%) Reduction in health-associated infections (52%) Suitable for water-resistant surfaces This technology can be deployed across several sectors including healthcare, commercial, industrial, and residential buildings on water resistant surfaces (floor and walls). The technology owner has successfully test-bedded the technology in local healthcare institutions. By varying the probiotics used, this technology may also be used in agriculture, aquaculture, animal husbandry and personal care applications to extend the benefits of probiotics into new products.

Fire Retardant Fibre Reinforced Polymer with Aerogel Jacket for Green Buildings
The regulations aimed at reducing carbon emissions have led to the adoption of a remodelling strategy that focuses on decreasing the energy usage of buildings. This can be achieved through measures such as thermal insulation and retrofitting, which extend the lifespan of buildings while reducing their energy consumption. The proposed technology by a Singapore-based research team utilises proprietary Fibre Reinforced Polymer (FRP) material for reinforcement to enhance the longevity of buildings. It contains a modified epoxy adhesive used in the FRP-adhesive-concrete interfaces to provide a range of advantageous properties, that include being 5 times lighter while 10 times higher tensile and flexural strength than steel, cost-effective in production, easily shaped, demonstrating high corrosion resistance, and offering both flexibility and tolerance to misalignment. In addition, through the modification of bonding agents and surface aerogel insulation, the fire retardancy of the material had been enhanced by 3 classes to V-0 rating according to the UL 94 plastic flammability standard. Among the superinsulation materials, aerogel stands out with its unique acoustic properties and significantly lower thermal conductivity of approximately 0.014 W/m.K. Additionally, it possesses exceptional physical and chemical attributes, such as its translucent structure. As a result, it is widely regarded as one of the most highly promising materials for thermal insulation in building applications. The FRP technology is currently pending fire testing to meet local regulatory requirements (e.g., BS 476 Part 20-23) and will be subjected to evaluation by the Building Innovation Panel of BCA in coming months. The technology owner is keen to support interested industrial partners to fabricate larger prototype of the FRP for test-bedding on site, and eventually license the intellectual property to the industrial partner for commercialisation. Through the external strengthening of structural components, the fire retardant FRP improves structural properties, leading to reduced environmental concerns, lower construction material costs, decreased labour requirements, and reduced CO2 emissions into the atmosphere. Silica aerogels typically exhibit a longitudinal acoustic velocity on the order of 100 m/s, making them suitable for various applications in acoustic devices for noise insulation. Furthermore, aerogels boast the lowest refractive index and dielectric constant among all solid materials. FRP is regarded as superior to conventional steel due to its notable advantages, including exceptional corrosion resistance, high flexibility, and tolerance to misalignment. It is also lightweight, cost-effective to produce, easy to shape, and possesses high tensile and flexural strength. Furthermore, FRP exhibits elastic properties. By modifying the bonding agent used in FRP-adhesive-concrete interfaces, the strength from the FRP developed using the proposed technology can be enhanced by 12%, and its flammability can be improved from an unclassified level to achieving a V-0 rating under the standard UL-94. Previously, aerogel found limited use in small-scale applications within the aerospace industry. However, there is now a growing trend of employing aerogel for larger building-integrated applications, aiming to reduce energy consumption. This has sparked renewed interest from both start-ups and established insulation manufacturers. The technology itself is relatively straightforward, making it an attractive choice for building owners and architects seeking a simple solution to lower energy costs. By incorporating aerogel insulation, buildings can enhance their energy performance and provide improved comfort and satisfaction for occupants. Remarkably, this technology can be applied to various types of buildings, including HDB flats, shop houses, commercial and industrial buildings, as well as both landed and non-landed housing units. Moreover, its versatility extends to both existing structures and new construction projects. Looking ahead, aerogel insulation is poised to play a significant role in the future of green building materials. Its applications extend beyond buildings and encompass areas such as architecture, vehicles, aircraft, spacecraft, and marine insulation. Meanwhile, fire retardant fibre reinforced polymer (FRP) materials have emerged as a valuable solution for building retrofitting and structural strengthening applications, particularly in terms of fire safety. These materials combine the strength and flexibility of FRP with fire-resistant properties, making them an effective choice for enhancing the fire resistance of existing structures or strengthening them to withstand fire-related incidents. When applied to building retrofitting, fire retardant FRP materials can be used to upgrade the fire performance of structural elements such as columns, beams, slabs, and walls. This approach is particularly beneficial for structures that do not meet current fire safety codes or have aged fire protection systems. The unique value proposition of aerogel insulation materials lies in their exceptional thermal performance, lightweight nature, versatility, moisture management capabilities, enhanced comfort, longevity, and environmental sustainability. These qualities make aerogel insulation materials an attractive choice for a wide range of building applications, offering significant energy savings and improved building performance. The fire retardant FRP is able to enhance fire resistance, provide structural strengthening, resist corrosion, offer lightweight and space-efficient solutions, ensure flexibility and ease of installation, offer cost-effectiveness, and provide design versatility. These qualities make fire retardant FRP materials a compelling choice for improving the fire safety and structural integrity of buildings.

High Power Battery Technology
Lithium-ion battery technology using graphite anode material is widely used in consumer electronics, electric vehicles and energy storage systems. However, for high-power, ultra-fast charge/discharge applications, e.g., regenerative braking in cars, electric buses, batteries for aircraft/marine sectors, graphite anode material is less preferred due to safety and performance limitations. Currently, lithium titanate oxide or LTO battery technology is one of the commercially available solutions for high power applications. LTO battery is a type of rechargeable battery that has a longer cycle life, faster charging and safer than conventional lithium-ion batteries. Despite these advantages, LTO battery is up to two times more costly than conventional lithium-ion batteries in the market, and has considerably lower specific energy density of about 60-110 Wh/kg than conventional lithium-ion chemistries, e.g., 90-165 Wh/kg for LFP and 150-270 Wh/kg for NMC.   The technology proposed by the Singapore-based research team relates to a method to synthesise a proprietary formulation of lithium-ion battery anode consists of mesoporous titanium dioxide (TiO2) material and robust LiMnFePO4 cathode. The research team's organisation holds patents related to synthesis of mesoporous TiO2 and LiMnFePO4 materials. This novel anode formulation for high power batteries is potentially able to reduce the production cost to about US$250 per kWh from US$500-600 per kWh for LTO, according to preliminary estimates by the team based on manufacturing capabilities in China. The cost reduction is derived from the use of cheaper TiO2 raw materials (vs. LTO) and the simple manufacturing process. The mesoporous TiO2 anode material can be integrated into existing manufacturing lines for lithium-ion cells without the need for new equipment. This TiO2 Li-ion cell chemistry offers inexpensive high power and safer battery technology. Using 18650 cylindrical cell of mesoporous TiO2 anode material with manganese-based cathode material, the cell achieved superior charging rate performance of up to 4C, energy density level of 70-100 Wh/kg and a cycle life of about 5,000 cycles, while retaining 80% of the initial capacity. The research team anticipated that the TiO2 cells will have up to 30% better energy density than LTO cell technology and 40-50% lesser cost than LTO technology. The research team is seeking industry partners to collaborate for a 5-10 kWh test bed project on a fast-charging application including uninterrupted power supply (UPS), regenerative braking and etc. The research team is able to tap on their in-house facilities to fabricate mesoporous TiO2 cells (21700 or 18650 format) using the novel anode formulation.   Cathode: LiMnFePO4 Anode: TiO2 Energy density: 70-100Wh/kg Charging: 3-4C in 15-20min Rapid pulse charging: 10-20C in 3-6min Discharging: 4-5C in 12-15 min Long cycle life: 5000 cycles No metal plating, no micro-shorting and no thermal runaway Lower cost than current high-power battery solutions in the market: estimated $250/kWh Relatively lesser supply chain issue hence easy to scale for market penetration Regenerative braking in cars, electric buses, aerospace and marine sectors Uninterrupted power supply systems in data centres or solar energy storage systems to address intermittency issues Depending on the type of applications considered, the market is segmented to different sectors including electric powertrain, aerospace/marine industries and energy storage systems. The global market for LTO batteries is expected to grow at a CAGR of 17.92% from 2022 to 2030. The growth of the market is driven by the increasing demand for LTO batteries in the aforementioned applications. Unlike the high-power battery solutions offered in the market, the proposed high-power battery technology solution is safe and inexpensive with moderate energy density, enabled by the mesoporous TiO2 anode material formulation. The team expected that the anode material formulation has relatively lesser supply chain issue thanks to abundance of its raw material, hence it is easy to scale up the technology for market penetration.

AI Model for Diagrammatic Abductive Explanations
As the world continues to make strides in artificial intelligence (AI), the need for transparency in the field intensifies. Clear and understandable explanations for the predictions of AI models not only enhances user confidence but also enables effective decision-making. Such explanations are especially crucial in sectors like healthcare where predictions can have significant and sometimes life-changing consequences. A prime example is the diagnosis of cardiovascular diseases based on heart murmurs, where an incorrect or misunderstood diagnosis can have severe implications. The technology, DiagramNet, is designed to offer human-like intuitive explanations for diagnosing cardiovascular diseases from heart sounds. It leverages the human  reasoning processes of abduction and deduction to generate hypotheses of what diseases could have caused the specific heart sound, and to evaluate the hypotheses based on rules. The technology tests which murmur shapes are present in the heart sound to determine the underlying cardiac disease. This approach of abductive-deductive AI reasoning can also be applied to other diagnostic or detective tasks. DiagramNet uses deep learning AI to perform four key steps: ‘Observe event’ by observing displacement to interpret its amplitude, murmur location, and the heart phase in which the murmur occurred. ‘Generate plausible explanations’ by listing possible diagnoses, retrieving respective murmur shape functions, and initialising their corresponding shape hypotheses. ‘Evaluate plausibility’ by fitting each hypothesis to the observation, evaluating the rules in terms of shape goodness-of-fit in conjunction with matching the murmur heart phase. ‘Resolve explanation’ with the hypothesis-fitted inference and the initial inference to make a final inferred diagnosis. By offering clinically relevant explanations in an accessible format, DiagramNet bridges the gap between complex AI predictions and user understanding, fostering trust and actionable insights in critical healthcare applications. Many existing AI models struggle to provide meaningful and easily interpretable explanations—they are either too technical or too simplistic. As such, there is an opportunity for a novel AI model that can generate thorough and easily understandable explanations. In the medical field, diagrams can be particularly beneficial when it comes to illustrating complex observations and making interpretations more accessible to non-technical users and patients alike. Enhances interpretation of AI decisions through a design framework for diagrammatic reasoning. Accelerates and strengthens the adoption of AI technology by leveraging diagrams that adhere to domain conventions. Presents a diverse array of explanation types, namely, abductive, contrastive and case-based explanations. Facilitates trust and consistency in AI-based cardiac diagnosis by providing murmur diagrams which are a universally understood tool among clinicians.

Timely and adequate rehabilitation is critical in facilitating post-stroke recovery. However, the organisation and delivery of rehabilitation are resource-demanding, and are only available in ~25% of stroke survivors in low-middle-income countries. Therefore, innovative solutions are urgently required to improve access to stroke rehabilitation services. Our team developed a platform to assist remote dissemination of physio- and occupational therapy services. Our platform enables post-stroke rehabilitation services to be delivered using consumer-grade devices (e.g., smartphones and tablet devices) and artificial intelligence technology, thereby breaking many physical and resource barriers to rehabilitation service access. Our platform is designed for hospitals, rehabilitation centres and post-stroke service providers. The system consists of two interfaces – the therapist portal and patient application. Portal system enables remote prescription of exercises and monitor exercise performance and progress, whereas the patient application acts as a “smart therapist” in providing real-time instructions and feedback. The system addresses limitations faced by the conventional phone interview- and video conference style of telemedicine, which mainly relies on self-reporting and subjective recall. Using devices’ built-in camera and relevant Internet of Things (IoTs), we automated the evaluation process using algorithms with key features identified by professional therapists for providing “supervision” through real-time feedback. The core technology utilizes artificial intelligence and computer vision. The bodily information is evaluated against experts’ criteria for providing real-time feedback to facilitate automated and “supervised” telerehabilitation. Features: Easy to setup and use, enable user to undergo rehabilitation with no time and place restriction Real-time feedback Validated objective measurements and evaluation Can be run on consumer-grade smartphones/tablets, no extra device required The system is suitable for use and applicataion in healthcare and residential care industry. Further rehabilitation-relevant services are under development to cater a wider spectrum of neurological conditions, including speech and cognition. Market – Elderly Health Centres, Elderly / Nursing Homes, Government, Social Welfare Departments or organizations, Individual for home use Distribution -- Worldwide, particularly in low-to-middle income countries where physical and functional (e.g., difficulty ambulating from home to centre), social (e.g., inconvenience of patient and/or caregiver), and financial barriers (e.g., costs, opportunity costs during working hours, and duration) are evident. Features: Easy to setup and use Close the gap in healthcare service using accessible and affordable technology Validated objective measurements and evaluation Customizable exercises and real-time feedback system Low hardware requirement, runs on consumer-grade smartphones/tablets, no extra device required The current “State-of-the-Art” of remote- and telerehabilitation adopted worldwide during the COVID-19 pandemic relies largely on the use of phone interviews and video conferences, which face limitations including labor-intense, subjective, and prone to recall bias. Our technology holds its UVP by addressing these limitations through automated and objective measurements via artificial intelligence and information captured using embedded cameras and other Internet of Things. It enables minimal human resources for monitoring and managing safe home-based rehabilitation. Infocomm, Artificial Intelligence

System for Testing Degradation in Bearings caused by Mechanical and Electrical Loads
Conventionally, the design consideration of bearings is very much driven by the mechanical loading condition. With the advancement of wide bandgap (WBG) power electronic devices and pulse-wide modulation (PWM) control techniques, the electrification of motor drive system has found wide applications due to its compact size and high-power conversion efficiency, such as electric vehicles and more-electric aircrafts. However, motor drive systems incorporating high-speed switching devices produce time-varying high-amplitude common-mode (CM) voltage, which results in undesirable CM current in the motor drive system that also flows through the bearings. This phenomenon causes frosting, fluting, and pitting on the bearing and leads to premature bearing failures, which results in unexpected downtime of critical systems. Existing bearing test systems focus on the impact of mechanical load on bearing degradation, but no comprehensive bearing test system is available to evaluate the bearing degradation due to both mechanical and electrical loads. A comprehensive test system with the ability to include the electrical load has been invented. The test system allows the life-span prediction of the bearing under varying electrical load conditions (pulsed current amplitude and repetition rate) at realistic operating conditions with adjustable axial force, rotational speed, and thermal conditions. The measurement data collected can be used to quantity the effectiveness of different bearing designs on extending the lifespan of the bearing under the influence of electrical load. The team is seeking a commercial partner to further develop and bring this technology into commercialization. The bearing test system consists of: (1) Bearing-holder on a rotating shaft; (2) Subsystem to emulate mechanical load; (3) Subsystem to emulate electrical load; (4) Data acquisition subsystem to monitor the vibration as an indicator of health degradation of the bearing-under-test; (5) Software algorithm to estimate the lifespan of the bearing-under-test. The test system has the following adjustable test conditions: (1) Rotational speed up to 2500 rpm; (2) Axial force up to 10 kN; (3) Pulsed circulating current in the bearing up to 3A peak; (4) Pulsed current frequency up to 10 kHz. The potential collaboration partners are test and certification laboratories and bearing manufacturers. The measurement data collected from the bearing test system help evaluate the quality and reliability of any motor-driven products consist of bearings. Therefore, it can be deployed in various industries where bearings are used, such as the automotive, aerospace industry, marine, and energy industries. The bearing test system generates valuable data and insights of the bearing health condition under varying electrical load conditions that can emulate different power ratings of the motor drive systems without building the full systems. It can assist to design and develop high-performance bearings that are immune to electrical loads. The potential customers of the test system are manufacturers of bearings, machinery and equipment manufacturers, electric vehicle manufacturers, and industries that use high-power motor drive systems. Bearings are virtually used in every kind of equipment or machinery, ranging from automobile parts, farm equipment, and household appliances to defence and aerospace equipment. The global bearing market size was valued at USD 111.59 billion in 2022 and is expected to grow at a compound annual growth rate (CAGR) of 10.6% from 2023 to 2030. As one of the major causes of machinery downtime and productivity loss, the issue of bearing failure has become increasingly important in various industries. Therefore, a comprehensive and cost-effective bearing test system becomes a valuable tool in the market. The current bearing test systems primarily concentrate on assessing the influence of mechanical load on bearing degradation. However, there have been no reported bearing test systems that incorporate both mechanical and electrical loads. To address this gap and evaluate the bearing degradation mechanism caused by advanced power electronic devices (i.e., the electrical load), a novel test system has been invented with the ability to include both the electrical and mechanical loads during testing.  Bearing Degradation, Bearing Performance Evaluation, Bearing lifespan prediction, Electrical Load Electronics, Power Management, Manufacturing, Assembly, Automation & Robotics
