Drionic is the commercial name given to a machine that uses electric currents through the skin in order to disrupt the function of the sweat glands also known as iontophoresis. In this case the person immerses his hands or feet in the drionic machine for a certain time. This has to be repeated quite often in order to get the desired results. Another company that produces iontophoresis equipment is the R.A. Fisher company.
