Abstract
A pressure sensor, a method for manufacturing the pressure sensor, and an electronic device are provided. The pressure sensor includes an electroluminescent device and a resistor layer. The resistor layer and one electrode of the electroluminescent device are connected to two electrodes of a power source respectively to form a loop. The pressure sensor is capable of converting a deformation amount caused by a pressure into a brightness change of the electroluminescent device, and determining a size of the pressure in accordance with the brightness change.
