Abstract
The invention is an induction heating system comprising a first article having a metallic mesh lining; and a second article having a coil for receiving an alternating electrical current; wherein the coil induces a current in the metallic mesh lining when the second pad is placed in close proximity to the first pad and the coil receives an alternating electrical current; whereby the current induced in the metallic mesh lining causes the metallic mesh lining to generate heat that can be applied to a body through contact with the first article. Additionally, this inventive induction heating system may further comprise a controller circuit in the second article for detecting an eddy current in the coil and operating a switch to turn the alternating electrical current off when no eddy current is detected in the coil.
