Figure 3. Electrical performance and motion-robust EMG recording of the nanomesh electrode. (A) Interfacial impedance of commercial Ag/AgCl gel electrode and nanomesh electrode transferred with AgNWs of various concentrations; (B) Photographs of EMG measurement and corresponding EMG signals acquired from Ag/AgCl gel electrode and nanomesh electrode during a hand-gripping action; (C) SNR of EMG signals acquired by the commercial electrode and nanomesh electrode. The results are presented as mean ± standard deviation (n = 3); (D) Interfacial impedance and (E) recorded EMG signals of the nanomesh electrode measured under initial dry conditions and water-containing state; (F) Interfacial impedance and (G) EMG signals under undeformed, stretching, compressing, and twisting deformation. EMG: Electromyography; AgNWs: silver nanowires; SNR: signal-to-noise ratio.
