Soft skin interfaces enhance haptic interactions. We focus on a soft electronic skin integrating PVDF (polyvinylidene fluoride tetrafluoroethylene) piezoelectric polymer transducers. Previous research revealed the PVDF’s output signal dependence on grasping speed, suggesting a viscoelastic mechanical behavior that the soft layer could influence, too. Through finite element analysis (FEA), we explore how the viscoelastic properties of the soft protective layer of an electronic skin affect stress transmission to the PVDF piezoelectric transducers below.
