1. A wearable structure comprising:
a first generator array having a plurality of first generators separated by a plurality of isolation layers, wherein at least one of said plurality of isolation layers has a different stiffness than at least one of said plurality of first generators, at least a portion of a first one of said plurality of first generators is operable to be mechanically distorted by a side of at least one tooth in order to provide a first electrical energy, said first electrical energy is provided to an energy storage device, and at least a portion of said side includes a curvature; and
a second generator array operable to be mechanically distorted in order to provide a second electrical energy to said energy storage device.
