本文介绍了一种新型触觉传感器的研发，该传感器设计采用压电元件作为传感器来工作。传统的触觉传感器由应变仪、导电弹性体和压电聚合物薄膜组成，仅仅局限于获取与压力或力相关的数据。然而，这里提出的新型传感器能够像人手一样检测物体的硬度和/或柔软度。已经进行了若干实验来研究其在机器人技术和医学领域的可能应用。结果表明，使用这种新型传感器对触觉感知性能进行可视化在机器人技术应用中非常有用；该传感器还能够检测外来物质以及皮肤的硬度。
This paper describes the development of a new type of tactile sensor which is designed to operate with a piezoelectric element employed as the sensor. Conventional tactile sensors, which consist of a strain gauge, conductive elastomer and piezoelectric polymer film, are confined solely to data acquisition relating to pressure or force, However, the new sensor proposed here is able to detect, very much like the human hand, the hardness and/or softness of an object. Several experiments have been carried out to investigate its possible applications in robotics and medicine. It is demonstrated that the visualization of tactile sensory performance using the new sensor is most useful in a robotics application; the sensor is also able to detect the hardness of an extraneous substance and that of skin.
