摘要 类似"人工皮肤"的触觉传感器在人工智能、医疗器械等领域有着广泛的应用。利用柔性电路板加工工艺设计了一种基于分布电容的触觉传感器,并分析了其工作原理。设计的触觉传感器主要由3层膜结构压制而成,包括上层电极层、中间间隔层和下层电极层,并在每一触元上表面粘贴一硅胶触点以增大灵敏度。针对柔性电路板的不同形式和间隔层不同厚度,加工了9种不同参数的触觉传感器,并对这9种传感器进行了量程、灵敏度、线性度等实验对比。实验证明,通过这2个参数的选择可以获得不同量程和灵敏度的触觉传感器,可根据实际应用场合选择具体参数以满足应用需求。同时阵列扫描实验证明设计的触觉传感器可以获得其表面的受力情况,并可以将触觉力在上位机上可视化的显示出来。 Skin-like tactile sensors are widely used in the field of artificial intelligence and medical devices. A kind of tactile sensor based on distribution capacitance with flexible printed circuit board technology is designed and its working principle is analyzed. The proposed tactile sensor is composed of three films including top-electrode layer,spacer layer and bottom-electrode layer,and a contact point is placed on the surface of each sensel. We fabricated9 different tactile sensors with different kind of flexible printed circuit board and different thickness of the spacer layer,and compared the experiment results of their measurement range,sensitivity and linearity. The results show that the tactile sensors with different measurement range and sensitivity can be fabricated by choosing different parameters,and can meet different application requirement. The experiment of array scanning shows that the designed tactile sensor can measure the force applied on its surface and the result can be displayed on the host computer visually.
