Title:	Miniature active concentric ring sensor for localized body surface EMG measurement

Abstract:	EMG detection is critical in gait analysis. Localized EMG detection usually calls for invasive method using needle electrode [1]. Body surface EMG provides global information about the muscle activity of a general area. This global information is not as useful compared with the localized EMG signal. Concentric ring electrode with build-in amplifier provides superior localized EMG signal from body surface. A light weight (2 gm) miniature (15mm in diameter 3.5 mm in thickness) active concentric ring sensor (Harbinger Technology HT-EMG, Chung-Ho City, Taipei County, Taiwan) with high input impedance (10 GΩ) is used to obtain localized EMG activity form body surface without skin preparation. The amplifier is mounted directly above the concentric ring electrode with low system noise (0.7mV rms at gain of 1000) with a high pass filter of 15 Hz and a low pass filter at 10KHz. The reference connection is at the back, on top of the active sensor. The high common mode rejection ratio (118dB typical) with high input impedance and lightweight makes concentric ring EMG active sensor user-friendly and easily adaptable to most EMG acquisition system.
