BPN776: Wearable Electronic-Tape

Project ID BPN776
Website
Start Date Fri 2014-Aug-15 21:50:03

Abstract We demonstrate a high-performance wearable piezoelectric electronic-tape (E-tape) for motion sensing based on a carbon nanotube (CNT)/silver nanoparticle (AgNP) composite encased in PDMS and VHB flexible thin films. E-tape sensors directly attached to human skin exhibit fast and accurate electric response to bending and stretching movements which induce change in conductivity with high sensitivity. Furthermore, E-tape sensors for a wide range of applications can be realized by the combination of controlling the concentration of AgNPs in the CNT network and designing appropriate device architectures. The reliability and scalability of E-tape sensors combined with compatibility with conventional micro-fabrication open up new routes for integration of nanoelectronics into flexible human interfaces at the system level.
