Stretch sensors are a type of sensor designed to measure soft structures, including soft robots and the human body. StretchSense, a company from New Zealand, has developed commercially available stretch sensors that can measure either stretch, bend, shear, or pressure. These stretch sensors are essentially flexible capacitors. When the sensor deforms (due to stretching or squeezing) its capacitance value changes. The sensor sends data about its capacitance to a Bluetooth...
