Claim 8:
9. The device of claim 1 wherein
the stimulus signal is an asynchronous signal that is unsynchronized with an output data rate of the electrostatic charge variation sensor,
the electrostatic charge variation sensor generates the second electrostatic charge variation measurement in a case where the first electrostatic charge variation measurement is less than a first threshold value, and
the processor determines the electrostatic charge variation sensor passed the self-test in a case where a parameter of the second electrostatic charge variation measurement is within a second threshold value of a parameter of the first electrostatic charge variation measurement, and determines the electrostatic charge variation sensor failed the self-test in a case where the parameter of the second electrostatic charge variation measurement is not within the second threshold value of the parameter of the first electrostatic charge variation measurement.
