Miniaturized flexible batteries for next generation wearable healthcare sensors

Global societal health challenges are increasingly reliant on the continuous monitoring of key indicators used to trigger aimed interventions. Only the timely sensing of specific biomarkers can underpin the prevention, diagnosis, and drug response necessary to make a societal change in healthcare. Wearable healthcare sensors for wireless real time remote monitoring of biomarkers can only rely on batteries. These should be flexible, small in lateral dimensions, non-flammable, and they should be based on widely available raw materials. FlexiMin proof-of-concept aims at demonstrating a flexible miniaturized battery to power next generation of wearable sensors of biomarkers in body fluids. The specific objective is to demonstrate the continuous powering of a commercial sensor as well as of a new class of sensors, which are the organic electrochemical transistors (OECTs), for the detection of specific biomarkers in either interstitial fluids or sweat. The goal is to demonstrate powering of individual sensors as well as of arrays of sensors for accurate medical diagnosis over days of operation and a Go-to-Market Strategy will be designed as one of the objectives of the project. FlexiMin will create a new solution for the newly growing market of wearable healthcare sensors for continuous monitoring.
