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. https://www.poolsproductscanadas.shop/product-category/aquavac-tigershark-parts/
