This application discloses a tactile sensor and its fabrication method. The tactile sensor includes a tactile membrane, an optical window, a cavity, a deformation structure, and a capacitor structure. The cavity is enclosed by a cavity wall and two opposing openings at both ends. The two openings respectively house the tactile membrane and the optical window. The deformation structure is located within the cavity and is used to absorb energy from an external light source. Under photothermal action, it deforms, thereby displacing the tactile membrane to generate tactile stimulation that can act on a target object. The capacitor structure converts the tactile stimulation into an electrical signal for tactile information acquisition. This application utilizes the deformation structure to deform within a certain temperature range, thereby displacing the tactile membrane and converting light energy into tactile output. This avoids the dependence of traditional light-driven tactile devices on closed air cavities, gas expansion, and suspended light-absorbing sheets, improving the structural stability and driving efficiency of the tactile sensor and increasing its environmental adaptability.
