Inspired by the human skin sensory mechanism, there are growing interests in creating a sense of touch in robotics. This work describes a new impedance based design to create an artificial tactile sensing skin. It has demonstrated that the electrical impedance tomography imaging technique allows for detecting the pressure distribution in a large area by a distributed touch sensor. The sensor is fabricated by filling a circular shaped phantom with liquid conductor and covering with an elastic shell on the top. The proposed sensor can detect the pressure applied to the elastic top using electrical impedance tomography imaging method. The sensor can therefore operate as a touch sensor mimicking a piezo-impedance operation in a simple fashion. The new sensor can differentiate between various force levels and their locations and thus produces a distribution of pressure. Such a simple sensor can function as a large area skin, enabling smarter human-machine interactions in emerging aug...

使用电阻抗层析成像的基于离子液体的分布式触摸传感器

受人类皮肤感觉机制的启发，在机器人技术中产生触摸感的兴趣日益浓厚。这项工作描述了一种新的基于阻抗的设计，以创建人造的触觉感应皮肤。已经证明，电阻抗层析成像技术允许通过分布式触摸传感器检测大面积的压力分布。传感器是通过在圆形体模中填充液体导体并在顶部覆盖有弹性壳而制成的。提出的传感器可以使用电阻抗层析成像方法检测施加到弹性顶部的压力。因此，该传感器可以以简单的方式用作模仿压电阻抗操作的触摸传感器。新的传感器可以区分各种力水平及其位置，从而产生压力分布。这种简单的传感器可以用作大面积的皮肤，从而在新兴的八月中实现更智能的人机交互。
