    Abstract: This application discloses a sensing apparatus, an electronic device, and a control method for the electronic device. The sensing apparatus includes a circuit board and a plurality of control points fixed to the circuit board, and each of the plurality of control points is located at a different position on the circuit board. Each control point includes memory alloy layers and elastic layers that are superposed and fixed in a one-to-one correspondence. When temperatures of all the memory alloy layers are lower than a specified threshold, all the memory alloy layers are located in a first plane. When a temperature of a specified memory alloy layer is higher than the specified threshold, the specified memory alloy layer is bent and deformed. Each memory alloy layer is connected to two electrodes for connecting the memory alloy layer to a circuit.

    Abstract: Disclosed is a tactile sensing device, including a light source, a plurality of optical waveguides, photoelectric sensing components, and a contact point. The light source is disposed at an input end of each optical waveguide, and the photoelectric sensing component is disposed at an output end of each optical waveguide. The plurality of optical waveguides surround the contact point, and the contact point is in contact with each optical waveguide. When there is a contact force at the contact point, the plurality of optical waveguides are deformed, and deformations of the optical waveguides cause losses of optical signals transmitted in the optical waveguides. The photoelectric sensing component obtains an optical signal transmitted by each optical waveguide, and may detect a value and a direction of the contact force based on a variation of the optical signal transmitted by each optical waveguide.
