Flexible surface myoelectric electrodes based on fiber skeleton reinforcement
A flexible surface myoelectric electrode based on a polydimethylsiloxane(PDMS)/silver paste/PDMS@fiber skeleton@flexible silver paste three-layer structure was proposed.The resistance changes under different external stimuli such as bending and twisting were analyzed,and the stability of the electrodes was evaluated through adhesion and ultra-sonic experiments.The results indicated that such a three-layered flexible surface EMG electrode had a high conductivity of below 0.5 Ω/sq,excellent resistance stability with a resistance change rate lower 3%after 1 000 bending),good me-chanical strength with an electrode-substrate adhesion higher than 1 000 N/m,and good skin consistency.When used for an electrical muscle sensor,the developed electrode could effectively recognize various movement intensities with a signal-to-noise ratio,which was 36%and 49%higher than those of the conventional Ag/AgCl gel electrode and copper elec-trode,respectively.
