Wearable, healthcare sensor sheets

Abstract

Healthcare is one of important factors for persons to keep their happiness during daily life. In order to maintaining good health conditions, daily continuous health monitoring is effective to find small symptoms before causing severe conditions. In this study, wearable, healthcare sensor sheets are proposed to monitor health conditions and activity, simultaneously, consisted of a skin temperature sensor, an electrocardiogram sensor, an ultraviolet sensor, a pH sweat sensor, and/or a three-axis acceleration sensor on a flexible film. The sensor sheets are fabricated by mainly printing methods in order to realizing macroscale and low-cost electronics. After characterizing each sensor, as a proof-of-concept demonstration, simultaneous human condition monitoring is conducted by attaching the device onto a volunteer's chest.
