We have developed a closed-loop, high-throughput system that applies electrical stimulation and optical recording to facilitate the rapid characterization of extracellular, stimulus-evoked neuronal activity. In our system, a microelectrode array deli

Electrical recordings of skeletal muscle activity [i.e., electromyogram (EMG)] provide information that can assist in the diagnosis of neuromuscular diseases and serve as command sources for prosthetic control. The application of stretchable multiele

The application of intramuscular electrode technology to a large muscle area, with the inter-electrode distance maintained, has the potential to increase both the controllability and observability of the muscle. To address such a need, this paper pre
