An electrical apparatus includes a battery, a circuit adapted to generate a periodic signal, and a wireless radio transceiver. The electrical apparatus further includes a control circuit adapted to set a characteristic of the periodic signal. The characteristic is received by an input of the wireless radio transceiver. The electrical apparatus further includes a first electrically conductive electrode adapted to electrically contact and puncture a first portion of a surface when the periodic signal is injected below the first portion of the surface. The periodic signal is coupled to the first electrically conductive electrode. |
