Written 3D-conductive Pathway in Leather for Highly Sensitive and Durable Electronic Whisker

Abstract

Printing methods are potential strategies to realize the fabrication of flexible electronics in large scale with low cost, which have been widely adopted to fabricate flexible electronic whisker (e-whisker). However, the sensors fabricated by these methods are typically fragile to surface damage as their conductive pattern is exposed on the surface. Here, conductive ink formed by zero-dimensional conductive nanomaterials is written on leather to fabricate leather-based e-whisker. Owing to the porosity of leather, the ink can permeate into leather and form a three-dimensional conductive pathway in it. The good mechanical properties and special structure of leather enable the sensor to have good performance in tape test, abrasion test and washing test. Furthermore, when scanning the surface of a substrate, the leather-based e-whisker is sensitive enough to detect a height difference of 50 μm, which make it capable of surface texture detection, spatial distribution mapping, and wind mapping, etc.
