We design a novel visual-tactile sensor that leverages thermochromic materials to simultaneously perceive temperature and tactile information. The sensor’s contact layer, made from thermochromic materials, changes color in response to temperature variations, allowing for the acquisition of thermal data through image processing with high sensitivity and reliable visual cues. By integrating both tactile and thermal sensing capabilities, this design enhances a robot’s ability to interact, particularly in scenarios where temperature plays a crucial role.

摘要

We design a novel visual-tactile sensor that leverages thermochromic materials to simultaneously perceive temperature and tactile information. The sensor’s contact layer, made from thermochromic materials, changes color in response to temperature variations, allowing for the acquisition of thermal data through image processing with high sensitivity and reliable visual cues. By integrating both tactile and thermal sensing capabilities, this design enhances a robot’s ability to interact, particularly in scenarios where temperature plays a crucial role.
