Abstract:
An electrode sheet including an electrode layer and a support layer may be provided. The electrode layer includes a first electrode and a second electrode. The electrode sheet is used to detect a capacitance change between the first electrode and the second electrode, which is changed according to a relative distance change between the electrode layer and a reference potential layer disposed apart from the electrode sheet. The support layer is made of a material which is bent when a pressure is applied thereto and which is restored to its original state when the pressure is released therefrom.
Abstract:
A pressure detection module may be provided that includes: a first electrode and a second electrode which are located on an insulation layer; and an elastic foam. The elastic foam is located between the first and the second electrodes and a reference potential layer located apart from the pressure detection module. 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. A magnitude of a pressure which causes the elastic foam to be transformed is detected according to the capacitance change.
