Human Interactive Wearable Devices: Applications of Artificial Electronic Skins and Smart Bandages

Wearable devices have high potentials for a wide range of applications for future electronics. One of the possible applications is human interactive devices for health monitoring system. In this study, we present high performance flexible and stretchable devices for artificial electronic skins and health monitoring system utilizing inorganic nanomaterial films patterned by printing methods as a proof of concepts. Inorganic-based flexible devices realize a low voltage operation <5 V compared to other flexible devices using organic materials. Mechanical flexibility and stretchability are experimentally characterized, and different types of applications are demonstrated. This inorganic-based printing method may lead the field in high performance flexible electronics and open new fields in human interactive wearable devices.
