摘要： The present invention relates to a system for a shoe sole with at least one piezoelectric element for generating electrical energy. In one embodiment, a system for a shoe sole comprises (a.) at least one piezo element adapted to produce an electrical signal upon mechanical deformation of the at least one piezo element, (b.) at least one first energy storage and at least one second energy storage, wherein the at least one first energy storage and the at least one second energy storage are adapted to store electrical energy obtained from the electrical signal, and (c.) at least one converter unit adapted to selectively control a transfer of an amount of electrical energy between the at least one first energy storage and the at least one second energy storage.
