Fig. 1From: Polymer-based flexible and multi-directional tactile sensor with multiple NiCr piezoresistorsSchematics of the polymer-based flexible tactile sensor with integrated multiple piezoresistors. The main structure is comprised of flexible and biocompatible materials including PDMS, PI, and SU-8. The patterned NiCr and double-layered Cr/Au lines serve as piezoresistor and electrode, respectivelyBack to article page
