Claim:
1. A power generating device, comprising: a first shell, having a first hollow portion and a first opening portion; a sensor module, configured in the first hollow portion of the first shell, wherein the sensor module comprises a magnetism element and an induction coil coiled on the magnetism element, the magnetism element comprises a first terminal and a second terminal and a first slide gap is formed between the first terminal and the second terminal; a magnetic module comprising a first magnetism element; a second shell, having a second hollow portion and a second opening portion, the second shell having a first fixture portion and a second fixture portion configured on the internal surface of the second shell, the magnetic module being configured between the first fixture portion and the second fixture portion; and an elastic element, configured between the first shell and the second shell; wherein when an external force is applied to the power generating device, there is relative movement between the second shell and first shell to cause the first magnetism element of the magnetic module to slide through the direction of the external force in the first slide gap to generate induced current in the induction coil and to compress the elastic element to generate a restoring force between the first shell and the second shell, wherein the directions of the restoring force and the external force are opposite.
