Article Title: A somatotopic bidirectional hand prosthesis with transcutaneous electrical nerve stimulation based sensory feedback

doi: 10.1038/s41598-017-11306-w

Figure Lengend Snippet: Schematic overview of the bidirectional experimental setup components. First ( a ) the sEMG signal is acquired from the residual stump muscles. Features are extracted from the signals and the classifier predicts the desired output class. The corresponding command is sent to the robotic hand ( b ), which moves accordingly. A force signal is measured from the robotic fingers sensors. This signal is then processed by the embedded computer ( c ), which computes the appropriate stimulation signal to elicit the desired sensation. This signal is then sent to the stimulator ( d ), which delivers the stimulation pulses to the subject’s stump via stimulation electrodes.

Article Snippet: The Hasomed surface stimulator was connected to a central single board computer (Odroid U3, Hardkernel) where a custom, multithreaded C++ code was running.
