(a) In vivo test setup to observe muscle stimulation artifact suppression (recording in sciatic nerve). (b–e) Top traces are the stimulation pulse waveforms, and the bottom trace is the output from RFE. (f) In vivo test setup to observe neural stimulation artifact suppression and (g) test results including comparison to conventional bipolar stimulation.
