This paper describes a new kind of multi-channel electrode for selectively interfacing the muscular system. Application of the system is similar to conventional intramuscular wire electrodes. A flexible polyimide thin-film structure is attached to a cannula which can be inserted into the muscle. The cannula can then be removed, so that only the polyimide electrode remains inside the muscle. Based...
Many neuroprosthetic applications require the use of very small, flexible multi-channel microelectrodes (e.g. polyimide-based film-like electrodes) to fit anatomical constraints. By arranging the electrode contacts on both sides of the polyimide film, selectivity can be further increased without increasing size. In this work, two approaches to create such double-sided electrodes are described and...
The acquisition of myoelectric signals from the Musculus deltoideus of a rhesus monkey is described. Such signals are aimed to be used as control signal for an active myoelectric hand prosthesis. For recording, implantable flexible, polyimide-based multi-site microelectrodes were placed epimysially on the muscle. EMG signals were recorded during voluntary goal-directed movements of the arm, and analyzed...
