Multimodal flexible sensor system

Long term stable monitoring and multi-tasking system using a machine learning

Abstract

This study aims to develop wireless multi-modal and multi-tasking flexible sensor sheets. To realize multi-modal flexible sensors, a variety of sensors using low-cost solution-based process are proposed to integrate on flexible films. In particular, by attaching the sensor sheet to human, monitoring of continuous vital signals is demonstrated. For multi-tasking system to make X-in-1 sensor, reservoir computing, which is one of machine learning techniques, is applied to a flexible sensor. As a proof-of-concept, weather sensor to detect rain droplet volume and wind velocity is developed. Although there are a lot of issues remained to move forward to realizing practical devices, proposed method may be able to open a door to build multi-modal and multi-tasking low-power sensor system in the future.
