abstract: An implantable EMG amplifier with a novel multiplexed frontend for in vivo selection of optimal electrode configurations, was designed using commercially available components. The multiplexers are advantageous as optimal electrode configuration are not known before implantation. The system has 6 ADC recording channels (ADS1298 biopotential amplifier, 2 kHz sampling frequency, 16-bit resolution), and three 8 × 8 multiplexer arrays (ADG2188), 2 channels per MUX. The system was characterised by measuring input impedance (5.8 MOhm) and frequency response (CMRR 49.0 dB; SNR 51.4 dB). EMG recordings from implanted epimysial electrodes showed lower signal quality (13.5 dB) compared with a commercial EMG recorder (19.5 dB), nonetheless the signals appeared suitable for myoelectric control applications. An implantable version of the EMG recorder, housed within a hermetically sealed ceramic package, should improve signal quality.
