Novel Linear Piezo‐resistive Auxetic Meta‐Sensors with Low Young's Modulus by a Core–Shell Conceptual Design and Electromechanical Modelling

Abstract Production of piezo‐resistive auxetic sensors is usually carried out through mixing and coating methods. Although these methods are beneficial, Young's modulus mixed becomes high because using a percentage sensing elements while the durability coated gets low due to separation from sensor surface. This article presents new core–shell metamaterial model address mentioned problems. The shell core produced polydimethylsiloxane (PDMS) rubber mixture PDMS/graphite powders (73.45 wt% graphite powders), respectively. A finite element developed via COMSOL software predict electromechanical behaviors created verified by an experimental study. Scanning electron microscope imaging conducted detect separations particles. main important feature this meta‐sensor possess linear sensitivity having zero Poisson's ratio. advantage method that does not decrease (unlike method), sensor‐coated particles do separate after method). introduced has advantages promote potential applications such as sensory gloves detect, for instance, human hand movements.
