Although in their white paper, they write that it is further amplified up to 120Vpp. It shouldn't use much power though, they note that the panel is only supplied with 0.5mA max, lower than many LED currents. They also say that it's the same amount of current used for conventional capacitive touch panels. Finally, the paper describes the sensations produced. Users have described various settings as feeling sticky or waxy, feeling akin to touching a motorcycle handle or rubber, or running a finger through a viscous fluid.
