A<unk>  or MENS (also microamperage<unk><unk><unk>  is a device used to send weak<unk>  signals into the body. Such devices apply extremely small microamp uA<unk>  currents (less than 1 milliampere mA) to the tissues using electrodes placed on the skin. One microampere uA is 1 millionth of an ampere and the uses of MENS are distinct from those of "TENS" which runs at one milliamp mA or one thousandth of an amp.
