Claim 5:
6. The device of claim 5, further comprising:
a second stimulus electrode configured to transmit the stimulus signal; and
a second receiving electrode underlying the second stimulus electrode, the second receiving electrode configured to receive the electrostatic charge variation in the surrounding environment,
the electrostatic charge variation sensor coupled to the first and second receiving electrodes,
the second electrostatic charge variation measurement being generated in response to the stimulus signal being transmitted by the first and second stimulus electrodes,
the electrostatic charge variation sensor configured to generate each of the first electrostatic charge variation measurement and the second electrostatic charge variation measurement based on a differential between electrostatic charge variation received on the first receiving electrode and electrostatic charge variation received on the second receiving electrode.
