Abstract：
Bionic skin has shown great potential in the fields of multifunctional robots and medical care. The tactile sensor, an important part of bionic skin, is used to measure the temperature, humidity, pressure, vibration, and other physical quantities including the external environment, object shape, and structure size. As a result, tactile sensors can be applied as epidermal sensors amounted on human skin to monitor the health and motion of users, and applied on soft robotics to help robots sense the environment information around. This paper analyzes and discusses the research progress of tactile sensing technology applied in bionic skin in recent years, including capacitive tactile sensors, piezoresistive tactile sensors, piezoelectric tactile sensors, photoelectric tactile sensors, magnetic tactile sensors, electrochemical sensors, and multi-component tactile sensors. In addition, the principle of each tactile sensor, advantages and disadvantages of various tactile sensors, and their practical applications in various fields are summarized. Finally, the future research direction of bionic skin sensing technology is outlooked.
摘要：
仿生皮肤在多功能机器人和医疗保健领域显示出巨大的潜力。触觉传感器，仿生皮肤的重要组成部分，用来测量温度，湿度,湿度压力,振动,和其他物理量，包括外部环境，对象形状,和结构尺寸。因此,触觉传感器可以作为表皮传感器应用于人体皮肤上，以监测用户的健康和运动，并应用于软机器人，以帮助机器人感知周围的环境信息。本文对近年来触觉传感技术应用于仿生皮肤的研究进展进行了分析和探讨,包括电容式触觉传感器，压阻式触觉传感器，压电触觉传感器，光电触觉传感器，磁性触觉传感器，电化学传感器，和多部件触觉传感器。此外,每个触觉传感器的原理，各种触觉传感器的优缺点，并总结了它们在各个领域的实际应用。最后,展望了仿生皮肤传感技术未来的研究方向。
