List of things what to try:

-Painted or vinyl cutter cut thin copper sticker as on body wireless power receiver.

-EL panel artificial nail

Research so far:

-EL panel can be cut to shape.

-There are flexible and stretchable fabric like EL panel

-EL panel can be painted on!? (How to insulate skin from both EL panel paint and hight voltage?) If works, glowing makeup and nail!
