Achieving skin-like tactile sensing for artificial instruments such as robotic hands and surgical grippers has long been a critical challenge. Due to the limited working space and strong interference, conventional commercial tactile sensors are hard to acquire force, shape, and temperature sensing abilities synchronously. In this paper, we present a soft multi-functional tactile sensor based on a soft silicon rubber grid covered with thermochromic liquid crystal ink, which can change the color of the surface when the temperature changes. The contact shape and contact force can be assessed by using a 3-D reconstruction method of soft silicon rubber grid, while the temperature can be estimated by color change.
