I am happy to advertise a new paper on surface EMG, just released by Frontiers:
Stable Myoelectric Control of a Hand Prosthesis using Non-Linear Incremental Learning
by Gijsberts, Bohra, Sierra González, Werner, Nowak, Caputo, Roa and Castellini
I would particularly like to point you at the movie that we have shot as supplemental material to the paper. as Frontiers is open access, you can download it from the above-mentioned page.
