Abstract
A system for event detection uses a resistive switching device to record a detected event. The resistive switching device has a resistance adjustable by an applied voltage. The operation of the resistive switching device is controlled by a controller, which is configured to apply a switching voltage to the resistive switching device at a start time, and turn off the switching voltage in response to an event signal indicative of occurrence of an event. The resistance value of the resistive switching device resulting from the application of the switching voltage is indicative of the detection of the event and also the time of the occurrence of the event.
