Abstract
The present invention provides an electrochemical timer device () having a source () and a drain () contact. The device further comprises a switch channel () and a delay reservoir () that are electrochemically interconnected with a gate electrode (). The switch channel () interconnects the source () and drain () contacts and is arranged to change electrical conductivity upon electrochemistry therein, and an electrochemical reaction is arranged to occur in the gate electrode () and delay reservoir () upon application of a drive voltage there between. The delay reservoir () is arranged such that the electrochemical reaction occurring therein gradually moves towards the switch channel () and eventually reaches the switch channel () after a delay time thereby changing the electrical conductivity of the switch channel ().
