Patent attributes
A new tactile sensor having a sensing layer, and the sensing layer includes a flexible substrate, at least one stress sensing unit, and at least one temperature sensing unit. The stress sensing unit includes a flexible conductive fiber, a top electrode, and a bottom electrode, the flexible conductive fiber is laid flat on the flexible substrate, the top electrode is bendable, and when there is a potential difference between the top electrode and the bottom electrode, a current flows along a radial direction of the flexible conductive fiber; and the temperature sensing unit includes a thermal conductive fiber and two end electrodes, the thermal conductive fiber is laid flat on the flexible substrate, and when there is a potential difference between the two end electrodes, a current flows along an axial direction of the thermal conductive fiber.
