Recent Progress in Human Skin-Inspired Multifunctional Flexible Tactile Sensors

Abstract

Tactile sensation plays a crucial role in human interaction with the environment, facilitating the perception of various physical stimuli such as pressure, texture and temperature through the skin. Mimicking human tactile perception, the development of flexible tactile sensors has seen significant growth, significantly expanding their applicability in robotics, medical devices and wearable technology. This paper reviews recent advances in flexible tactile sensor technology, with a focus on the development of multifunctional sensors capable of detecting multiple types of tactile stimuli simultaneously. Unlike traditional rigid sensors, flexible tactile sensors integrate the sensitivity and elasticity of human skin, enabling them to adapt to different surfaces and detect a wider range of stimuli.
