Piezoelectric Sensors: Self‐Powered Real‐Time Arterial Pulse Monitoring Using Ultrathin Epidermal Piezoelectric Sensors (Adv. Mater. 37/2017)

In article number 1702308, Keon Jae Lee and co-workers demonstrate a self-powered, flexible piezoelectric pressure sensor on an ultrathin substrate via an inorganic-based laser lift-off process for detecting various physiological signals in near-surface arteries. The radial pulse signals are wirelessly transmitted to a smart phone using a Bluetooth module, which realizes the possibility of a self-powered and real-time healthcare-monitoring system.
