1. A pressure detection module comprising:

  • a first electrode and a second electrode which are located on an insulation layer; and

    an elastic foam,wherein the elastic foam is located between the first and the second electrodes and a reference potential layer located apart from the pressure detection module,wherein a capacitance between the first electrode and the second electrode is changed according to a relative distance change between the reference potential layer and the first and the second electrodes through a transformation of the elastic foam,and wherein a magnitude of a pressure which causes the elastic foam to be transformed is detected according to the capacitance change.
