The era of the Internet of Things
(IoT) requires sustainable and
convenient methods to power widely distributed sensing devices. Self-powered
systems have emerged as a potential solution that utilizes ambient
energy from environmental sources such as electromagnetic fields,
mechanical motion, solar power, and temperature gradients. Recently,
the integration of wireless technologies with self-powered systems
has attracted significant attention as a way to address challenges
in energy harvesting and transport without the cost and inherent physical
constraints of wires. This review summarizes recent progress in the
application of wireless technology in self-powered systems for applications
in harvesting ambient electromagnetic energy and in transferring power
between devices. In addition, challenges and development trends in
the future of wireless self-powered sensor networks are discussed.
Heterogeneous multi-compartmental DNA hydrogel particles fabricated via microfluidic assembly were incorporated with a tandem DNA sequence logical circuit for precision medicine against cancers.
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.
