Power generating device and object embeeding the same

A power generating device, comprising:

• a first shell having a first hollow portion and a first opening portion;
• a magnetic module having a base portion and a first magnetic element;
• a sensor module configured in the first hollow portion, wherein the sensor module comprises a magnetism element and an induction coil coiled over the magnetism element, and the sensor module has a slide gap;
• a second shell covering the first shell, wherein the second shell has a second opening portion for the magnetic module to pass through;
• and
• an elastic element configured between the magnetic module and the first shell, and the first magnetic element capably moving back and forth along the slide gap;
• wherein the distance of the first magnetic element moving back and forth is within a range between two millimeters to five millimeters.

A object, comprising:

• a body;
• and
• a power generating device embedded in the body, the power generating device comprising:
• a first shell having a first hollow portion and a first opening portion;
• a magnetic module having a base portion and at least one first magnetic element;
• and
• a sensor module configured in the first hollow portion, the sensor module comprising a magnetism element and an induction coil coiled over the magnetism element, the magnetism element comprising a first terminal, a second terminal, and a slide gap between the first terminal and the second terminal;
• wherein when an external force is applied to the power generating device, the first magnetic element capably moves back and forth along the slide gap to generate an induced voltage;
• wherein the distance of the first magnetic element moving back and forth along the slide gap is between 2 mm to 5 mm, and the induced voltage is greater than 3V.
