Abstract

AbstractBiomimetic artificial muscles (BMAMs) aim to imitate the movement and capabilities of natural muscles, drawing inspiration from their structure and function. This research utilized multiwalled carbon nanotubes to increase the conductivity of the electrode membrane and replaced traditional electroactive polymers with sodium alginate to improve the output performance of BMAMs. To further strengthen the output force of the electrode membrane, nanoscale ZnO was chosen as the doping material. Various composite electrode membranes were created during the experiments, each containing varying amounts of ZnO nanoparticles. The membranes' surface morphology was extensively examined with scanning electron microscopy, and the composite electrode membranes were fully assessed on an electrochemical workstation. Electrochemical testing showed that adding nanoscale ZnO particles greatly boosted the specific capacitance of the electrode membrane, which was directly linked to the performance of BMAMs. Impedance spectroscopy test results indicated a minimal impact of nanoscale ZnO particle doping on the internal resistance of the electrode membrane.Highlights Sodium alginate replaces electroactive polymers, easing environmental impact. Nano ZnO doping boosts electrode membrane's capacitance for stronger muscles. ZnO doping shows minimal effect on electrode membrane's resistance.
