An only slightly less simple followup circuit also ratios sensor capacitance to a reference capacitor to measure micrometers…this time linearly. Figure 1 The U1a and U1b cross-coupled Schmidt trigger ...
Abstract: This paper presents an absolute capacitive rotary encoder using a sample-and-hold demodulator (SHD) to reduce interference between sine and cosine channels. The capacitive encoder measures ...
Abstract: Tactile perception is essential for fine interaction and environment awareness in next-generation humanoid robots. However, most flexible tactile sensors suffer from a fundamental ...
