Engineers 3D-Print Personalized, Wireless Wearables That Never Need a Charge

Wearable sensors to monitor everything from step count to heart rate are nearly ubiquitous. But for scenarios such as measuring the onset of frailty in older adults, promptly diagnosing deadly diseases, testing the efficacy of new drugs or tracking the performance of professional athletes, medical-grade devices are needed. University of Arizona engineers have developed a type of wearable they call a “biosymbiotic device,” which has several unprecedented benefits. Not only are the de...
