摘要

A device for producing electric energy including a first element converting mechanical energy into electric energy. The level of the electric energy is variable according to the variations of the mechanical energy. A controller block is connected to the first element for providing measurement data on the basis of the electric energy produced by the first element. The controller block includes a detector block to examine the electric energy produced by the first element to form the measurement data. A first energy storage unit stores electric energy produced by the first element and provides the electric energy for the operation of the controller block. Also, a system, a tire and a method.
