Sustainability

Health and Well-Being

Sustainability is becoming an essential part of both everyday life and the healthcare sector, influencing how we live, care for ourselves, and manage resources to create a healthier and more resilient future. Singapore is embracing green healthcare innovations, where technology and sustainable living solutions converge to promote healthier lifestyles, preventive care, and the development of a robust, eco-conscious healthcare system.

This curated selection of sustainable living and healthcare innovations addresses modern challenges and enhances quality of life. From digital health, including AI in healthcare, to personal care, wellness, to efficient resource management and green materials, these innovations open new opportunities for enterprises to develop products and services tailored for families, the silver generation, and eco-conscious individuals, promoting well-being and sustainable growth.

The integration of digital health innovation and AI in healthcare is transforming how we approach both personal and preventive care. These technologies enable more efficient healthcare delivery, while aligning with sustainable living solutions, reducing resource consumption and promoting long-term wellness. By integrating technology into healthcare, Singapore is paving the way for a more sustainable, resilient, and health-conscious future.

Real Time, All-day, Stress Monitoring System Using Data Science

There are 30,000 occupational drivers in Singapore, out of which 13,500 are 45 years old and above. The risk of acquiring cardiovascular disease increases with age and is potentially exacerbated by low physical activity and high emotional stress levels, which are two typical characteristics of occupational drivers arising from their work environment. Low level of physical activity and high stress levels have been shown to have significant relationship with heart rate variability, one of the indicators of cardiovascular disease. This technology is developed to help drivers to monitor their stress level, provide them with instantaneous feedback and the necessary alerts for a timely intervention. This technology offer presents a cross-platform AI system that estimates the stress levels continuously in real time, and can be easily integrated with commercially available photoplethysmography (PPG) wearables, e.g., a PPG wristwatch. In addition, this technology can be adapted for the monitoring of workplace stress with the aim of improving overall mental well-being.

Dilution Air Processing Unit for Reduced Transmission of Airborne Infectious Diseases

The Dilution Air Processing Unit (DAPU) is an ideal solution for small and medium businesses to prepare themselves for the Covid-19 new normal by employing an enhanced air ventilation technique. The DAPU system allows the creation of zones (e.g. sickbays, waiting rooms, etc.) within workplaces with no recirculation of air. This prevents cross-contamination of unclean air in between the zones. This solution is suitable for hotels and other premises to be used for quarantine purposes. The DAPU consists of the following key features: Provides 100% fresh air supply with no recirculation Reduces airborne particles exposure by greater than 60% Achieves 25% energy efficiency in providing 100% fresh air supply as compared to conventional systems Uses fully portable modular approach Can be easily retrofitted to any existing air-conditioning system resulting in lower implementation cost The DAPU can also be deployed in any area without an existing air-conditioning system making it highly versatile.

Novel Anti-microbial Agent for Preventing Dental Caries

The cause of caries (tooth decay) is a formation of biofilm lying on the teeth and subsequently becoming mature. The acid created by specific bacteria (S. mutans) dissolves the hard tissues of the teeth (enamel), which can result in pain and difficulty with eating or even tooth loss and infection. Severe dental caries can impair quality of life but is preventable by maintaining good oral hygiene such as using fluoride toothpaste with brush and dental floss or toothpick to clean between the teeth. However, small children, older adults or people with severe disabilities may find it hard to apply. Besides, Fluorosis may be resulted if there is overexposure to fluoride. People with Fluorosis will develop white opaques on their tooth surface, which affect the appearance. In addition, some mouthwash products contain chemicals like alcohol and chlorhexidine to help kill bacteria. The use of these chemicals has some potential drawbacks like altered taste sensation and staining of teeth. Our new compounds, dihydro-resveratrol or its derivatives can be used for preventing the formation of biofilm and inhibit the growth of bacteria which are cost-effective and very safe to use as they are herbal extracts, which have fewer harmful effects in comparison with those chemical‐based products.

Stable, Plant-based Photoactive Antimicrobial Agent

Antimicrobial resistance developed due to the overuse of conventional antimicrobial agents in surface coatings and consumer products is a global concern for treatment of infectious diseases in recent years. To address this concern, US FDA has banned the use of a number of conventional antimicrobial agents in consumer and healthcare products such as hand soaps and hand sanitisers. This raises the importance of alternative antimicrobial agents in antiseptic products. Photoactive antimicrobial agents are effective alternatives which produce highly reactive oxygen species (ROS) when activated by light. These reactive oxygen species display broad-spectrum biocidal activity that destroy microbes by a multi-targeted killing mechanism, which may limit the development of antimicrobial tolerance or resistance. The researchers have developed a stabilised form of a plant-based antimicrobial agent to protect it from environmental degradation. The enhanced environmental stability of this natural photoactive antimicrobial agent has made it suitable to be incorporated in various materials for the self-sterilising product applications and may provide a “greener solution” to limit the spread of pathogens and transmission of infections by indirect contact.
