Nature has created high-performance materials and structures over millions of years of evolution. Inspired by the concepts and design principles evident in natural materials and structures, high-performance tactile sensors, based on bioinspired structures/functions, natural biopolymers, and biomimetic strategies, have been developed. However, the primary challenge is to develop novel sensing mechanisms and device structures that are sufficiently sensitive and stretchable using bioinspired materials. Herein, we review the recent advancements made in this field, focusing on biomimetic approaches to produce tactile sensors with essential sensing capabilities and the development of bioinspired materials with the desired electrical and mechanical properties. In addition, we highlight the potential applications of these devices and discuss the potential directions for future work.

经过数百万年的进化，大自然创造了高性能材料和结构。受天然材料和结构中明显的概念和设计原理的启发，基于仿生结构/功能、天然生物聚合物和仿生策略的高性能触觉传感器已经开发出来。然而，主要挑战是使用仿生材料开发足够灵敏和可拉伸的新型传感机制和设备结构。在此，我们回顾了该领域的最新进展，重点关注仿生方法来生产具有基本传感能力的触觉传感器，以及开发具有所需电气和机械性能的仿生材料。此外，
