Chronic in-vivo testing of a 16-channel implantable wireless neural stimulator

Annu Int Conf IEEE Eng Med Biol Soc. 2015 Aug;2015:1017-20. doi: 10.1109/EMBC.2015.7318537.


Here, we report on chronic in-vivo testing of a 16-channel wireless floating microelectrode array (WFMA) in a rat sciatic nerve model. Muscle threshold currents, charge injection levels, and charge density were monitored for electrodes of two WFMA devices implanted into animal subjects over a five month period. This type of wireless stimulation device could eliminate problems associated with percutaneous connectors for a variety of neural prostheses and other medical devices.
