Abstract: The present disclosure relates to pressure-sensitive detection apparatus. One example apparatus includes a pressure sensor array located in a touch display screen. One half-bridge circuit is constituted in each row of the pressure sensor array. When there is a touch input signal on the touch display screen, a first half-bridge circuit and a second half-bridge circuit corresponding to a touch location of the touch input signal output signals. A deformation amount generated when pressure is applied to a first pressure sensor component in the first half-bridge circuit is less than a deformation amount generated when the pressure is applied to a second pressure sensor component in the first half-bridge circuit, and a deformation amount generated when the pressure is applied to a first pressure sensor component in the second half-bridge circuit is greater than a deformation amount generated when the pressure is applied to a second pressure sensor component in the second half-bridge circuit.

Abstract: Embodiments of the present invention provide an automobile including a processor and a sensing apparatus, and the sensing apparatus is installed on a part that is of the automobile and that may be in contact with a hand of a driver, and includes a transmitter and a receiver. The transmitter sends a sound wave signal to the hand of the driver, and the receiver receives a reflected sound wave signal reflected by the hand of the driver, converts the reflected sound wave signal to an electrical signal, and sends the electrical signal to the processor. The processor analyzes the electrical signal to obtain a feature of the reflected sound wave signal, and recognizes an identity of the driver based on the feature of the reflected sound wave signal.
