Abstract

An active electrode (d10 mm, t6 mm) that functions as an impedance transformer (with an input impedance >10 G Omega and an output impedance <1 Omega ) by means of which one can derive surface EMG without any skin preparation and paste is presented. This electrode was compared with a conventional one, and it was ascertained that the electrode could replace the conventional one and was preferable because it required less preparation time and was less affected by environmental noise.
