Patent ID: 8422293

Claim:
A self-powered detection device comprising: (a) at least a non-volatile memory cell; and (b) a sensor activated by a physical or chemical action or phenomenon, wherein the sensor forms an energy harvester that transforms energy from the physical or chemical action or phenomenon into an electrical stimulus pulse, wherein the non-volatile memory cell is arranged for storing, by using the electrical power of the electrical stimulus pulse, at least a bit of information relative to detection by the sensor of at least a first physical or chemical action or phenomenon applied to the sensor with at least a given strength or intensity, wherein the non-volatile memory cell comprises a first FET transistor having i. a control gate; ii. a first diffusion defining a first input; and iii. a second diffusion defining a second input, and wherein the first FET transistor is set to a written logical state from an initial logical state when, in a detection mode of the self-powered detection device, the non-volatile memory cell receives on a set terminal, among the control gate and the first and second inputs, a voltage stimulus signal resulting from the first physical or chemical action or phenomenon.
