WEARABLES
Another breakthrough in wearable sensors opens interesting possibilities
Printed directly onto the skin, one of the applications of the technology could be to monitor the symptoms of COVID-19
We are already using sensor technology in our daily lives — from smartphones, smartwatches to fitness trackers, which keep track of various health indicators. Over the years, these wearable sensors have become more accurate & efficient, but they have always required some complex circuitry working underneath.
Recent breakthroughs have transformed the bulky devices of yesteryears into flexible patches that stick to people like temporary tattoos. One of the previous studies that I wrote about included the development of multifunctional sensors and circuits that could be easily printed on the skin via a new form of electronics dubbed as “drawn-on-skin electronics” (DoS).
Researchers at Penn State University have now developed biosensors that could be safely printed onto the skin. These sensors can track health markers like body temperature and blood oxygen levels, before being washed off. The team led by Huanyu Cheng, at the University’s Department of Engineering Science and Mechanics, built on their previous work on flexible printed…
