Abstract: An ultrasonic tactile sensor for detecting a clamping force includes an ultrasonic detector and a sensing layer, and the sensing layer includes a first soft layer and a second soft layer, and the first soft layer has plural spherical microstructures arranged in contact with the ultrasonic detector, so that after a pressure is applied to the sensing layer, the ultrasonic detector generates an ultrasonic wave and receives a reflected wave signal, and the signal is provided for identifying the contact area of the spherical microstructures and deriving the force exerted on the tactile sensor.
