Electromagnetic absorbers are essential in energy, stealth, and communication technologies, yet current designs underperform.

By using the lead-free piezoelectric thin films and energy harvesting devices of this research, we will develop autonomous power sources with the combination of all-solid thin-film secondary batteries ...

A Syracuse University research team has introduced a new concept for designing ultra-thin absorbers that enables absorbing layers with a record-high bandwidth-to-thickness ratio, potentially several ...

EPFL researchers have designed flexible, batlike wings that boost lift and improve flight performance. This innovation could ...

Nexperia has introduced an inductor-less energy harvesting IC that is able to cold start with 12μW from 270mV. Called NEH7100BU, it can mediate between a harvesting power source, a USB charger, a ...

New research elucidates the raindrop's impact and the physical dynamics that help the leaf respond, with potential applications for agriculture and renewable-energy harvesting. In the paper ...

A design of voltage doubler circuit has been studied in context of electromagnetic energy harvesting using 28 nm FD-SOI technology. After analysis of the operating constraints of the circuit, the ...

Unlike birds and insects, bats have flexible wings made of a thin membrane, allowing them to fly more efficiently. Inspired by this, researchers at EPFL’s School of Engineering have designed bat-like ...

This half-inch square ultra-low power energy harvesting LiPo cell charger by [Kris Winer] uses a low voltage solar panel to top up a small lithium-polymer cell, which together can be used as the ...
