Electrochemical device

a technology of electrochemical devices and chips, applied in the direction of instruments, antenna supports/mountings, antennas, etc., can solve the problems of limiting the ability to mass-produce the tags to lower prices, difficult and expensive (>0.50 usd) manufacturing, and the chips used in prior art devices suffer from a lack of environmental friendliness, processability and economic production possibilities

Abstract

An electrochemical device is provided, comprising a source contact connected to a first antenna pad, a drain contact connected to a second antenna pad, at least one gate electrode, an electrochemically active element arranged between, and in direct electrical contact with, the source and drain contacts, which electrochemically active element comprises a transistor channel and is of a material comprising an organic material having the ability of electrochemically altering its conductivity through change of redox state thereof, and a solidified electrolyte in direct electrical contact with the electrochemically active element and the at least one gate electrode and interposed between them in such a way that electron flow between the electrochemically active element and the gate electrode(s) is prevented. In the device, flow of electrons between source contact and drain contact is controllable by means of a voltage applied to the gate electrode(s).
