Recent progress in tactile sensors and their applications in intelligent systems

Abstract

With the rapid development of intelligent technology, tactile sensors as sensing devices constitute the core foundation of intelligent systems. Biological organs that can sense various stimuli play vital roles in the interaction between human beings and the external environment. Inspired by this fact, research on skin-like tactile sensors with multifunctionality and high performance has attracted extensive attention. An overview of the development of high-performance tactile sensors applied in intelligent systems is systematically presented. First, the development of tactile sensors endowed with stretchability, self-healing, biodegradability, high resolution and self-powered capability is discussed. Then, for intelligent systems, tactile sensors with excellent application prospects in many fields, such as wearable devices, medical treatment, artificial limbs and robotics, are presented. Finally, the future prospects of tactile sensors for intelligent systems are discussed.
