📰 Smart wearable tracks your hydration in real time
The article discusses the importance of staying hydrated and introduces a new wearable hydration sensor developed by researchers at the University of Texas at Austin. The sensor uses bioimpedance to detect early signs of dehydration by measuring tissue conductivity. It connects wirelessly to a smartphone app to provide real-time feedback on hydration levels. The device is seen as practical for various scenarios, including athletes, first responders, and office workers. The research team conducted experiments to validate the sensor’s accuracy and reliability, showing promising results for everyday use. The team aims to further improve the sensor’s capabilities and make hydration tracking more seamless and accessible to a wider population.
📰 At-home test works like coffee rings to spot serious illness faster
Researchers at UC Berkeley have utilized the coffee ring effect to develop a groundbreaking medical test for rapid disease detection. This innovative test can identify diseases like COVID-19, prostate cancer, and sepsis with remarkable accuracy, delivering results in just twelve minutes. The test works by capturing and concentrating disease markers at the edges of a droplet, making detection easier. By using light-reactive particles, the test can provide visible results that can be verified using an AI-powered smartphone app. This stain-inspired science brings hospital-level disease detection to the home, allowing individuals to take charge of their health quickly and affordably.
📰 Want a faster grocery trip? These AI smart carts can help
Wegmans, a popular grocery chain in the northeastern U.S., is testing artificial intelligence-powered Caper Carts that show shoppers their running total in real-time and allow them to skip the checkout line.
