Initial findings reveal that electrical resistivity is significantly affected by concentration MWCNTs/GNPs, with minimum more than 0.5% needed to achieve responsive composite. Moreover, piezoresistive analysis indicates increase MWCNTs/GNPs stress levels leads improvement stress/strain-sensing performance. When subjected equivalent levels, variations fractional changes (FCR) exhibit increasing trend decreasing resilient modulus, stemming from decrease stiffness due increased MWCNTs/GNPs. Additionally, electrochemical impedance spectroscopy (EIS) demonstrates contraction Nyquist plots under compressive ramp loading prior failure, followed expansion curves post-failure. Scanning electron microscopy (SEM) images visually showcase bridging effects MWCNTs filling GNPs within structure.
