Abstract:
A power transmitter according to an aspect of this technology comprises an antenna unit and a signal generation circuit. The antenna unit has: a first antenna conductor that, when used, is brought into contact with a human body that is not grounded; and a second antenna conductor that is capacitively coupled to the ground without being brought into contact with the human body. The signal generation circuit applies an AC power signal between the first antenna conductor and the second antenna conductor.
