چکیده
In this paper, the creep behaviour of stretchable interdigital capacitive (IDC) large strain sensors is studied. A generalized Kelvin-Voigt (GKV) model used to study sensor’s substrate material, manufactured from silicone elastomer (Ecoflex 00−30) with barium titanate (BTO) filler. Creep experiments are performed on 10, 20, 30 and 40 wt% BTO nanoparticles dimensions 100 nm 200 dispersed in elastomer. The was increase overall permittivity substrate, hence raising capacitance IDC sensor. effect GKV parameters studied detail through analysis response. pristine Ecoflex predominately a hyperelastic which shows negligible creep, while addition particles led composite exhibiting such that behaves like visco-hyperelastic material. Hence, results affecting electrical sensing performance during static loading conditions. This information provides insights impact composition creep-resistance output signal sensor (capacitance).
