Abstract
One embodiment of the present invention discloses a circuitry and an element which can be activated, charged, or interacted using any useful source of EM-radiation which is able to emit a suitable EM-field, which circuitry or element can be produced in a cost-effective manner, as well as a method for charging the same. The circuitry or element includes an antenna for receiving and converting EM-radiation into electric energy; a rectifier for converting the energy to a rectified current, and a dechargeable energy cell. The energy cell includes, in at least one embodiment, a first and a second electrochemically active element, which are electronically separated from each other, and an electrolyte which is arranged in ionic contact with at least a portion of both the first and second electrochemically active element, wherein the energy cell is arranged to receive rectified current from the rectifier, and to convert the rectified current into stored energy by altering its electrochemical state in response to the rectified current.
