Abstract
A method for event sensing employs an event sensor comprising a detector and circuitry, connected thereto, produced by printed electronics processes. Operation may rely on fixed characteristic devices, such as a series resistive chain, or variable characteristic devices such as thin film transistors (TFTs) and the like. A pulse is input to the printed electronic circuitry. The printed electronic circuitry divides the pulse across the various devices comprising the circuitry according to pulse amplitude and pulse width. The circuitry provides an output signal which is provided to a plurality of display elements capable of indicating the division performed at the printed electronic circuitry. In one embodiment, each display element is an electrophoretic display which changes contrast as a function of the applied voltage. Not only the pulse amplitude and pulse width, but the number of pulses applied to the printed circuitry (i.e., sensed by the detector) may be indicated.
