A self-generating power supply apparatus includes a power generating body, an energy harvester, and a power consumer. The power generating body generates an electromagnetic field when a force is applied, an energy of the electromagnetic field is received by the energy harvester and subsequently transferred to the power consumer; or alternatively, the energy harvester is not provided and the energy of the electromagnetic field is directly received and used by the power consumer. The energy of the electromagnetic field is harvested by the energy harvester contacting or not contacting the power generating body, and then is converted into electrical energy, which is transferred out in a wired or wireless manner to enable self-generating power supply for the apparatus. The self-generating power supply apparatus has an immeasurable impact on the development in the fields such as wearable devices, small mobile communication devices, Internet of Things, new energy etc.

A system, device and method are provided for continuously generating more than 0.01 watt of electrical energy by harnessing mechanical or kinetic energy from a reciprocating motion of a user's torso during breathing. The reciprocating motion causes reciprocating lateral and medial translation of two chambers of the device housing. That reciprocating lateral and medial translation rotates a gear, which in turn, drives a dynamo to produce electrical energy. Since the conversion from the mechanical energy of the spinning rod to power is direct, the energy-conversion efficiency may be up to 90% or higher. The device may further comprise one or more charging means for providing electrical energy to one or more peripheral electronic devices. In some embodiments, additional integrated functions may include auxiliary energy storage, backup energy, emergency power, mini-MP3 player, data recorder, GPS interface, miniature video recorder, speaker, abdomen muscle exercise, timing, Bluetooth interface, and heath information analyzer.
