Can your pads be powered by a DC electric power supply like a battery?Does the controller transform the Ac to dc like the Biomat does?

All our products use AC (alternated current) electricity in the power outlet, not DC (Direct current) electricity as in the battery.

DC electricity does not produce any EMFs at all. However, it is not enough power to warm up many pounds of crystals infused in the mat to such a high temperature (up to 70C inside the pad, under the crushed stones) so that the crystals release enough infrared light.

AC heating system is not a problem for us; we apply many technologies to get almost EMF-free safe, robust, and durable products.
