Abstract

A self-contained chest motion electricity generating device which converts normal respiratory breathing motion into electrical energy. The device employs a magnetic circuit which includes a permanent magnet and an induction coil wrapped around a ferromagnetic core. The magnetic circuit is mounted on a chest harness which includes shoulder straps and a chest strap. The chest strap includes an elastic materal which expands and contracts with normal respiratory motion. The permanent magnet and the induction coil of the magnetic circuit is separated by the elastic material such that in the totally exhaled state, a minimal gap exists between the permanent magnet and the ferromagnetic core. Normal breathing action expands and contracts the elastic material, thus varying the separation distance between the induction coil and the permanent magnet in such a fashion as to vary the magnetic flux linkage with the induction coil, thereby inducing a current through the coil. This induced current is then made available from leads attached to the induction coil as usable electrical power.

Claims

1. A chest motion electricity generating device comprising:

magnetic flux generating means;

induction coil means, said magnetic flux generating means and said induction coil means forming a magnetic circuit;

an elastic separator connected to said magnetic flux generating means and said induction coil means, said elastic separator located between said magnetic flux generating means and said induction coil means;

non-elastic chest harness means which includes at least one adjustable chest strap for surrounding the circumference of the human chest, said chest strap provided with two ends, said two ends respectively attached to said magnetic flux generating means and said induction coil means;

whereby normal respiratory motion causes expansion and contraction of said elastic separator, said respiratory motion thereby changing the magnetic flux linkage between said magnetic flux generating means and said induction coil means, and thereby generating an induced EMF across said induction coil means, said induced EMF being made available as useful electrical energy.

2. A chest motion electricity generating device according to claim 1 wherein said magnetic flux generating means comprises:

a permanent magnet mounted on a diamagnetic magnet mounting plate and attached to said mounting plate by fastening means.
