Claim 1:
2. The apparatus of claim 1, wherein the driver unit further includes:
a rechargeable battery for providing a battery-supplied electrical voltage;
a power management module for regulating the battery-supplied electrical voltage to a regulated voltage;
a high-voltage booster module for boosting up the regulated voltage to yield a boosted voltage;
a high-voltage multiplexer (MUX) for controllably switching on and off the boosted voltage to generate the plurality of pulsed voltage signals;
a microcontroller unit (MCU) configured to at least control the high-voltage MUX in switching the boosted voltage for generating an individual pulsed voltage signal with a desired pulse frequency and a desired duty cycle; and
a flexible printed circuit board (FPCB) on which at least the power management module, the high-voltage booster module, high-voltage MUX and MCU are mounted.
