Feasibility Study Of Ingestible Sensor Platform Powered By Gastric Acid Battery For Daily Health Care

In this study, we have proposed an ingestible sensor platform utilizing gastric acid battery for daily healthcare. This platform has a fundamental application to precisely measure core body temperature as one of the most useful vital signs for health check. It also has the expandability to add various biosensors such as pH, pressure sensors etc.. The architecture without a conventional battery is essential to human body safety and environmental load reduction. In addition, the size and cost are expected to be reduced. This paper reports on the feasibility study of the proposed system and key technical elements.
