Abstract
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.
