This invention is an apparatus to produce electrical power from the wearer's respiration through the application of a circular cluster of Variable Reluctance sensors that are excited by a rotating disk holding a plurality of magnets arranged radially, on its face, and spaced uniformly about its circumference. The sensors' arrangement conforms to the circumference and are perpendicular to the face of the rotating disk. This arrangement produces corresponding sinusoidal voltages that are each converted to DC via a corresponding rectifier circuit. The resulting DC voltage outputs are then summed to produce a single power output, which is fed to a DC-to-DC converter. The rotating disk's unidirectional motion is produced by a ratchet gear system attached to a partially elastic torso garment, which is worn on the mid torso. The ratchet gear system moves proportionally, in response to the reciprocal motion of a wearer's respiration.
