In minimally invasive surgery, tactile feedback is lacking. An elastoresistive tactile sensor is designed to feel inside the body of the patient. The sensor is thin, flexible, robust, cheap, and has a simple structure. It has 16×16 elements, a spatial resolution of 1 mm and a bandwidth of 78 Hz. Despite a large hysteresis and non-linear behaviour, the sensor is very well suited for a qualitative measurement of the pressure distribution, with a high resolution in position, force and time.
