a, Photograph of repeated intramuscular EMG signal recordings on rabbit leg muscles via HNA-implanted Pt/Ir FEHs at multiple muscle sites, with induced sciatic nerve stimulation. b,c, EMG signal fragments (b) and power spectral densities (c) recorded over 4-h duration using HNA-implanted FEHs. d, Graphs comparing intramuscular EMG signals acquired at different muscle sites by TFRFP- and HNA-implanted Pt/Ir FEHs at different time points. e, Analysis of the EMG amplitude variation recorded by TFRFP-implanted FEHs during repeated recordings (n = 5 peaks per group). f, Power spectral densities recorded over time by TFRFP-implanted FEHs from different muscles of a rabbit’s leg during spontaneous and gentle leg movement.
