First-in-human demonstration of floating EMG sensors and stimulators wirelessly powered and operated by volume conduction.

ABSTRACT:

Background

Recently we reported the design and evaluation of floating semi-implantable devices that receive power from and bidirectionally communicate with an external system using coupling by volume conduction. The approach, of which the semi-implantable devices are proof-of-concept prototypes, may overcome some limitations presented by existing neuroprostheses, especially those related to implant size and deployment, as the implants avoid bulky components and can be developed as threadlike devices. Here, it is reported the first-in-human acute demonstration of these devices for electromyography (EMG) sensing and electrical stimulation.

Methods

A proof-of-concept device, consisting of implantable thin-film electrodes and a nonimplantable miniature electronic circuit connect
