“智能材料”，如压电体，是在许多应用中执行复杂功能所需的重要材料类别。这些材料的不同之处在于它们能够对变化的刺激做出积极反应，这是将机械能转换为电能的结果，反之亦然。本文主要研究基于压电材料的触觉传感器。本文首先讨论了为什么压电式换能器对触觉感觉很重要。简要概述了一些历史里程碑，如压电效应的发现和压电材料在各种应用中的应用。基于电学和弹性现象的混合，用基本的数学公式解释了压电效应。给出了对压电现象的简单解释，以帮助理解这种现象是如何在各种基于压电材料的传感器中被利用的。最后，给出了一些压电式触觉传感器的实例。

“Smart materials” such as piezoelectrics are important class of materials needed to execute sophisticated functions in many applications. These materials are distinguished by their ability to react actively to changing stimuli as a result of converting mechanical to electrical energy and vice versa. This article focuses on the piezoelectric material-based tactile sensors. The article begins by discussing why piezoelectric transduction is important for tactile sensing. A brief overview of some historical milestones, such as the discovery of the piezoelectric effect and the utilization of piezoelectric materials in various applications, has been presented. The piezoelectric effect has been explained with basic mathematical formulations based on the intermingling of electric and elastic phenomena. A simple explanation of the piezoelectric phenomenon has been presented to help understand how this phenomenon is exploited in various piezoelectric material-based sensors. Finally, some examples of piezoelectric tactile sensors are presented.
