用于脊髓损伤后功能恢复的先进神经假体的开发是神经工程研究中发展最快的方向之一。其中最令人兴奋的解决方案是网络神经假体（NNP）系统，包括一个分布式网络的植入组件，以感知和刺激整个身体。这些系统正在用于SCI患者，以提供抓握和到达功能，但目前没有任何关键的健康监测功能。事实上，由于其组件放置在肌肉附近，NNP平台非常适合皮下记录来自肌肉的光电容积描记图（PPG）信号，这对于植入式血压监测是有希望的。此外，NNP系统组件遍布全身的分布式特性非常适合无线电容供电，这是一种新的模式，在对弯曲、未对准和E&M干扰的敏感性方面优于电感链路。
The development of advanced neuroprostheses for restoration of function after spinal cord injury (SCI) is one of the most rapidly growing directions for neuroengineering research. Among the most exciting solutions is a networked neuroprosthesis (NNP) system, comprising a distributed network of implanted components to sense and stimulate throughout the body. These systems are being used with SCI individuals to provide grasp and reach functions, but do not presently feature any critical health monitoring. In fact, due to placement proximity of its components to muscles, an NNP platform is ideal for subcutaneous recording of the photoplethysmogram (PPG) signal from muscles, which is promising for implanted blood pressure monitoring. Also, the distributed nature of NNP system components throughout the body is ideal for wireless capacitive powering, a new modality with advantages over inductive links in terms of sensitivity to flexion, misalignment, and E&M interference.
