DOI: 10.1016/j.enconman.2021.114505
Abstract: Abstract Owing to the excitation level of ambient vibrations, the wideband performance of multi-stable energy harvesters and parametrically excited energy harvesters is restricted. The bistable periodic interwell motion and parametric resonance initial threshold amplitude primarily… read more here.

DOI: 10.1142/s1758825120500337
Abstract: In this paper, an effort is made to study the chaotic motions of a dielectric elastomer (DE). The DE is activated by a time-dependent voltage (AC voltage), which is superimposed on a DC voltage. Th... read more here.
