A novel multi-modal tactile sensor design using thermochromic material

Tactile sensors are important for ensuring robotic perception [1], and their performance directly affects a robot’s capability for performing dexterous operations. These sensors mimic the tactile sensing capability of human hands. This is because the skin of human hands is involved in considerably meticulous works and can provide multimodal perceptions of various factors, including the thermal conductivity, weight, surface texture, and stiffness. Therefore, the investigation of multimodal tactile sensors has recently become increasingly popular.
