Claim:
1. A smart device having ability for rejecting mistaken touching, comprising: a capacitive button module, disposed on the smart device, and the capacitive button module comprises: a contacting layer; a first electrode layer, comprising a first electrode; a second electrode layer, disposed under the contacting layer, and comprising at least one second electrode and at least one third electrode; and an elastic layer, disposed between the first electrode layer and the second electrode layer, configured for operatively generating a deformation when the elastic layer receives a pressure, such that a distance between the first electrode layer and the second electrode layer is changed; wherein the first electrode and the second electrode form a first inductive capacitor, the second electrode and the third electrode form a second inductive capacitor; when the elastic layer receives the pressure and generates the deformation, a pressing signal is generated according to a capacitance variation of the first inductive capacitor; when a conductor is close to or in contact with the contacting layer, a moving signal is generated according to a capacitance variation of the second inductive capacitor.
