A Research on Implantable Microelectrodes for EMG Signal Acquisition

Abstract:

Signal acquisition microelectrode works as an interface between tissue and circuit in neural engineering. Stable, precise and lossless detection of EMG is important to functional neuromuscular stimulation. In this paper, we propose an implantable microelectrode for EMG acquisition fabricated by MEMS technology and test the impedance of several microelectrodes fabricated with different parameters. By analyzing the amplitudes and power spectrum of the EMG signals acquired from rabbits by fabricated microelectrodes, the signal acquisition performances of the microelectrodes are evaluated and compared both in time domain and frequency domain.
