Abstract
An apparatus includes a flexible support member having a first and second ends and a plurality of guides there between. The apparatus further includes an electrical generator having a magnet, an electrical coil surrounding the magnet, and a pair of electrical leads for delivering electrical current generated in the coil. A tensile member is connected between the first end of the support member and the magnet, wherein the tensile member extends along a path from the first end of the support member through the plurality of guides to the magnet. A spring element biases the magnet in a direction to impart tension to the tensile member. Deflection of the support member from a relaxed position to a deflected position modifies the length of the path of the tensile member to displace the magnet within the electrical coil and generate an electrical current.
