Superelastic lightweight carbon materials for piezoresistive sensors

Abstract

This article aims to give a comparative overview on carbonic materials of various geometries and compositions, which are developed for applications in production of strain and pressure sensors. We discuss the preparation methods and resulting geometries of carbonic porous materials, hybrid and reinforced composites. Various architectures combined with synergistic effect of graphene and additional components reveal a series of mechanical properties (compressibility, fatigue resistance, time of recovery) and variation of electrical parameters, which make them suitable for integration in wearable electronics as highly sensitive devices. Presented materials refer to own investigations and published studies of other research groups.
