Abstract

The present invention relates to an electronic device, which can be triggered by the proximity of bioelectric fields, or by the motion of charges and ions. The triggered element of the device can be controlled between the two states: on and off. From this point of view it can be considered a switch. However, the triggered element can also attain all the intermediate states between the on and off states, according to the intensity of the external stimuli. From this point of view it can be considered a sensor, since its response is directly related to the sensed stimulus.

Claims
