Highly Stretchable Strain Sensor and Detecting System for Monitoring of Bladder Volume

Abstract

This paper demonstrates a highly stretchable strain sensor fabricated using biocompatible materials for bladder monitoring application. We fabricate Ecoflex-CNT strain sensors, and additionally formed AuCNT composite on the CNT film to increase stretchability as well as sensitivity. Furthermore, the monitoring system for the device using Arduino is developed. Our result shows that the device operates well within 200 % strain range, and allows to monitor the change with the monitoring system. © 2021 IEEE.
