Wireless Powering and Energy Harvesting to Ultra-Thin Flexible Healthcare Devices

Abstract

The organic electronics enables flexible, large-area, and distributed sensor and/or actuator array and is suitable for the wearing-unconscious devices used in biomedical and healthcare applications. Power delivery to ultra-thin flexible devices with the thickness of 1um to 10um, however, is a challenge, because wired connections and rigid battery are not allowed. To solve the problem, novel flexible devices for wearable healthcare applications with the energy harvesting or the wireless powering using organic circuits are proposed and demonstrated. In this talk, I will show an insole pedometer with piezoelectric energy harvesters, a fever alarm armband with solar cells, and a wet sensor sheet in a diaper with wireless powering.
