Abstract:Piezoelectric energy harvesters (PEH) require an electronic circuit to rectify their AC voltage in order to supply wireless sensors. In the literature, it has been shown that such electronic circuit can be tuned and optimized in order to enhance the bandwidth and power of linear PEH. However, to date, few works have explored the electrical optimization of non-linear bistable PEH. The present work reports the optimization of the harvested power and bandwidth of bistable PEH by mean of a non-linear energy extrac… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
