An electronic device includes: a foam is located below an OLED display, and a film is located below the foam. Multiple bridge circuits are disposed on the film. Each bridge circuit includes two parallel branches. A first branch includes a first and a third resistor. A second branch includes a second and a fourth resistor. At least one of the four resistors is bonded to the foam. At least one resistor is not bonded to the foam. The resistor that is bonded to the foam is made from a first material. A strain sensitivity coefficient of the first material is greater than 100. A film area in which the resistor that is bonded to the foam is located is covered by a second material. A Young's modulus of the second material is greater than 30.

Electronic device and terminal

An antenna adjustment system and a base station, where the antenna adjustment system includes an inertial feedback unit configured to detect a swing angle of an antenna when the antenna swings with a housing, and send an angle signal to a controller, an actuator and an elastic element configured to control an auxiliary board to rotate back in a direction opposite to a swing direction of the housing in order to counteract deflection caused by swing of the housing of the antenna fastened to the auxiliary board. The actuator is driven by the controller based on the angle signal. Therefore, a position of an antenna can be adjusted with swing of the antenna such that signal sending stability of the antenna can be ensured.
