Self-Powered Wearable Biosensors

ConspectusWearable biosensors hold the potential of revolutionizing personalized healthcare and telemedicine. Advances in chemical sensing, flexible materials, scalable manufacturing techniques now allow wearables to detect key physiological indicators such as temperature, vital signs, body motion, molecular biomarkers. With these systems operating on skin, they enable continuous noninvasive disease diagnosis health monitoring. Such complex devices, however, require suitable power sources order realize their full capacity. Emerging wearable energy harvesters are attractive for addressing challenges a supply. These convert various types ambient (e.g., biomechanical energy, biochemical solar energy) into electricity. In some circumstances, harvested electrical signals can directly be used active sensing parameters. On other hand, single or hybrid harvesters, when integrated with management circuits storage could additional well signal processing data transmission electronics. Self-powered sensor operate continuously sustainably without an external supply promising candidates next generation electronics Internet Things.This Account highlights recent progress self-powered sensors toward healthcare, covering biosensors, storage, strategies.
