用于信息传递的触觉驱动器中的智能材料
A Review of Smart Materials in Tactile Actuators for Information Delivery
摘要：
皮肤作为人体最大的器官，是人体接受外界触觉刺激的重要感觉通道。通过触觉感知的信息，人们可以感觉和猜测物体的性质，如重量，温度，质地和运动等。事实上，这些性质是通过皮肤中的各种受体接收到的对我们大脑的神经刺激。机械，电和热刺激可以刺激这些受体，并导致不同的信息通过神经传递。已经开发了用于致动器以提供机械、电或热刺激的技术。这些包括静态或振动致动、静电刺激、聚焦超声等。智能材料，例如压电材料、碳纳米管和记忆合金，在提供触觉驱动方面发挥着重要作用。本文旨在回顾人类触觉感知的背景生物学知识，了解我们如何通过触觉感知世界并与世界互动，以及传统和最先进的触觉反馈传递技术。
英文摘要：
As the largest organ in the human body, the skin provides the important sensory channel for humans to receive external stimulations based on touch. By the information perceived through touch, people can feel and guess the properties of objects, like weight, temperature, textures, and motion, etc. In fact, those properties are nerve stimuli to our brain received by different kinds of receptors in the skin. Mechanical, electrical, and thermal stimuli can stimulate these receptors and cause different information to be conveyed through the nerves. Technologies for actuators to provide mechanical, electrical or thermal stimuli have been developed. These include static or vibrational actuation, electrostatic stimulation, focused ultrasound, and more. Smart materials, such as piezoelectric materials, carbon nanotubes, and shape memory alloys, play important roles in providing actuation for tactile sensation. This paper aims to review the background biological knowledge of human tactile sensing, to give an understanding of how we sense and interact with the world through the sense of touch, as well as the conventional and state-of-the-art technologies of tactile actuators for tactile feedback delivery.
