A flexible, multi-site tactile and thermal sensor (MTTS) based on polyvinylidene fluoride (resolution 50 50) is reported. It can be used to implement spatial mapping caused by tactile and thermal events and record the two-dimensional motion trajectory of a tracked target object. The output voltage and current signal are recorded as a mapping by sensing the external pressure and thermal radiation stimulus, and the response distribution is dynamically observed on the three-dimensional interface. Through the mapping relationship between the established piezoelectric and pyroelectric signals, the piezoelectric component and the pyroelectric component are effectively extracted from the composite signals. The MTTS has a good sensitivity for tactile and thermal detection, and the electrodes have good synchronism. In addition, the signal interference is less than 9.5% and decreases as the pressure decreases after the distance between adjacent sites exceeds 200 mm. The integration of MTTS and signal processing units has potential applications in human-machine interaction systems, health status detection and smart assistive devices.

据报道，一种基于聚偏二氟乙烯的灵活的多点触觉和热传感器（MTTS）（分辨率50 50）。它可用于实现由触觉和热事件引起的空间映射，并记录跟踪的目标对象的二维运动轨迹。通过感测外部压力和热辐射刺激，将输出电压和电流信号记录为映射，并在三维界面上动态观察响应分布。通过建立的压电信号和热电信号之间的映射关系，可以从复合信号中有效地提取压电分量和热电分量。MTTS对触觉和热检测具有良好的灵敏度，并且电极具有良好的同步性。此外，信号干扰小于9.5％，并且在相邻站点之间的距离超过200 mm之后，随着压力的降低而降低。MTTS和信号处理单元的集成在人机交互系统，健康状态检测和智能辅助设备中具有潜在的应用。
