Power generation technology based on piezoelectric nanocomposite materials

(PhysOrg.com) -- Among the vast number of untapped energy sources are finger taps, heartbeats, and even hamsters running on exercise wheels. In a recent study, researchers from Georgia Tech have shown that ...

The journal, Nano Letters, recently published an article highlighting the fascinating nanogenerators developed by Dr. Yong Shi, a professor in the Mechanical Engineering Department at Stevens Institute of Technology. The pa ...

After six years of intensive effort, scientists are reporting development of the first commercially viable nanogenerator, a flexible chip that can use body movements — a finger pinch now en route to a pulse beat in the ...

By combining a new generation of piezoelectric nanogenerators with two types of nanowire sensors, researchers have created what are believed to be the first self-powered nanometer-scale sensing devices that ...

Imagine if all you had to do to charge your iPod or your BlackBerry was to wave your hand, or stretch your arm, or take a walk? You could say goodbye to batteries and never have to plug those devices into ...

(PhysOrg.com) -- To power a very small device like a pacemaker or a transistor, you need an even smaller generator. The components that operate the generator are smaller yet, and the efficiency of those foundational components ...

It all starts with a single octahedron structure, then after four iterations there are already 625 of them. Each iteration creates a new octahedron at each vertex. The result is a fascinating 3D fractal construction ...

(Phys.org) —A team of researchers headed by Professor Raffaele Mezzenga has created a hybrid material out of gold and milk proteins that looks like a wafer-thin gold leaf. Thanks to its properties, it could ...

(Phys.org) —Scientists from ETH Zurich have developed a nanomaterial that protects other molecules from oxidation. Unlike many such active substances in the past, the ETH-Zurich researchers' antioxidant ...

(Phys.org) —Waste from textile and paint industries often contains organic dyes such as methylene blue as pollutants. Photocatalysis is an efficient means of reducing such pollution, and molybdenum trioxide ...

(Phys.org) —Researchers at Rice University have come up with a new way to boost the efficiency of the ubiquitous lithium ion (LI) battery by employing ribbons of graphene that start as carbon nanotubes.

(Phys.org) —Cheaper clean-energy technologies could be made possible thanks to a new discovery. Research team members led by Raymond Schaak, a professor of chemistry at Penn State University, have found ...
