Abstract: A capacitive pressure sensor is provided. The capacitive pressure sensor comprises a dielectric layer, a light-transmitting first electrode, a second electrode, a display layer and a measuring device. The dielectric layer is made of a foam. The first electrode is disposed on a first surface of the dielectric layer, wherein a pressure is applied to the first electrode. The second electrode is disposed on a second surface of the dielectric layer opposite to the first surface. The second electrode includes a plurality of unit electrodes having a predetermined shape. The display layer is disposed between the first electrode and the dielectric layer or between the second electrode and the dielectric layer. The measuring device is configured to detect a measurement value of a capacitance of the dielectric layer for each unit electrode by causing a potential difference between the first electrode and the second electrode.
