Wrapped with wires with a magnet in the center powered by two 9V batteries. It's meant to double the rate of blood circulation. But it's still very less effective. It a based on Tony Stark's arc reactor, as a chest piece.

I designed the circuit using Proteus(tm) software and etched the board with traditional(!) ironing method. some electronics guys said I had chosen the tracks too narrow and the circuit components too sparse! I will correct it in next projects.
