Tactile sensors that possess the physical properties of human epidermis, which can sense external stimuli (pressure, temperature, humidity, etc.), are a very popular cutting‐edge innovation. They make a large contribution to extensive applications in the real‐time monitoring of human health, artificial intelligence, robot systems, and biocompatibility. However, great challenges remain in large‐scale tactile simulation to attain fast data transmission and low signal crosstalk among the pixels. The tactile sensor arrays based on a transistor matrix (TSATMs) are thus investigated for large‐scale pressure mapping. Currently, a variety of TSATMs with different device structures have been described. The integrated composite structure, consisting of a transistor matrix and a pressure‐dependent electronic component, was first widely employed for tactile mapping. Then, researchers conducted a large amount of scientific inquiry into the intrinsic pressure‐sensitive transistor. These pressure‐dependent transistors are based on changes in the specific gate capacitance, piezotronic effect, piezo‐phototronic effect, and triboelectric nanogenerator. Certainly, novel systems and materials, low‐power consumption, and multifunctional design should be considered for the next generation of intelligent TSATMs to meet the needs of diverse practical applications.

基于晶体管矩阵的大规模触觉传感器阵列的最新进展

具有人类表皮物理特性的触觉传感器可以感应外部刺激（压力，温度，湿度等），是一种非常流行的前沿创新。它们为人类健康，人工智能，机器人系统和生物相容性的实时监控中的广泛应用做出了巨大贡献。但是，在大型触觉仿真中，要在像素之间实现快速数据传输和低信号串扰，仍然存在巨大挑战。因此，针对大型压力映射，研究了基于晶体管矩阵（TSATM）的触觉传感器阵列。当前，已经描述了具有不同设备结构的各种TSATM。集成的复合结构，由一个晶体管矩阵和一个与压力有关的电子元件组成，首先被广泛用于触觉测绘。然后，研究人员对本征压敏晶体管进行了大量的科学探究。这些依赖于压力的晶体管基于特定的栅极电容，压电效应，压电光电效应和摩擦纳米发电机的变化。当然，下一代智能TSATM应当考虑采用新颖的系统和材料，低功耗和多功能设计，以满足各种实际应用的需求。
