Towards a full-stack peripheral nerve recording interface: Challenges on integration and possible solutions

Peripheral nerve recording interfaces are a new frontier in neuroprosthetic applications. Nevertheless, an integrated medical device offering both electroneurographic (ENG) signal sensing and decoding is still missing. This paper aims to summarize the process of integrating existing technologies into a full-stack recording device. To this end, the system requirements are provided, together with a description of the building blocks that compose a recording interface: electrode, acquisition system, classification algorithm, power and communication units. The core of our contribution is a detailed analysis of the unsolved conflicts which arise during the assembling process, followed by the proposal of a few compromise solutions.
