利用商用元件设计了一种植入式肌电放大器，该放大器具有一种新颖的多路前端，可在体内选择最佳电极配置。多路复用器是有利的，因为最佳电极配置在注入之前是未知的。该系统具有6个ADC记录通道(ADS1298生物电位放大器，2 kHz采样频率，16位分辨率)和3个8×8多路复用器阵列(ADG2188)，每个多路复用器2个通道。该系统的特点是测量了输入阻抗(5.8欧姆)和频率响应(共模抑制比49.0分贝；信噪比51.4分贝)。植入肌膜电极的肌电记录显示信号质量(13.5分贝)低于市售的肌电记录仪(19.5分贝)，但这些信号似乎适合肌电控制应用。植入版本的肌电记录器，安装在密封的陶瓷封装中，应该会改善信号质量。
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.
