  • Title: Surface electromyographic electrode pair with built-in buffer-amplifiers.
    Author: Fujisawa M, Uchida K, Yamada Y, Ishibashi K.
    Journal: J Prosthet Dent; 1990 Mar; 63(3):350-2. PubMed ID: 2308095.
    Abstract:
    By means of a surface electrode with an operational amplifier, a new electrode unit suitable for an electromyographic-biofeedback apparatus and for portable electromyography used outside a Faraday cage was developed. The operational amplifier, which has an output impedance lower than 10 ohms, functions as an efficient buffer amplifier and is able to protect the EMG signals from background noises. This new electrode unit is small (32 x 12 x 5 mm), waterproof, and inexpensive. Because its structure is simple, it can be built in any laboratory.
