Circuit transfers four times more power out of shakes and rattle

Penn State engineers have optimized an energy harvesting circuit so that it transfers four times more electrical power out of vibration – the ordinary shakes and rattles generated by human motion or machine operation.

Using their laboratory prototype, which was developed from off-the-shelf parts, the Penn State researchers can generate 50 milliwatts. Although they haven’t tried it, they believe the motion of a runner could be harnessed to generate enough power to run a portable electron

New system for storing lithium-polymer energy

The basque technology centre CIDETEC is working on a project about lithium-polymer energy with the collaboration of the companies CEGASA and ZIGOR.

Actually, they are in the first stage of the project. Initially, they analysed the structure, design and development of different electrode materials with multiple characteristics (cathode and anode) to use lithium-polymer in batteries.

The results of the project enabled the development of a lab-scale prototype of a rechargeable

Wisconsin team engineers hydrogen from biomass

In the search for a nonpolluting energy source, hydrogen is often cited as a potential source of unlimited clean power. But hydrogen is only as clean as the process used to make it. Currently, most hydrogen is made from fossil fuels like natural gas using multi-step and high-temperature processes.

Now, chemical engineers at the University of Wisconsin-Madison have developed a new process that produces hydrogen fuel from plants. This source of hydrogen is non-toxic, non-flammable and can be

NIST Team Reports Method to Characterize New Insulating Materials for Microelectronics

Advance Should Speed Semiconductor Industry Search

Researchers from the Commerce Department’s National Institute of Standards and Technology (NIST) reported today they have developed methods for characterizing key structural features of porous films being eyed as insulators for the ultrathin metal wires that will connect millions of devices on future microprocessors and increase processor speed. The advance, reported today at the American Chemical Society’s national meeting

LECs may be future of flat panel color displays

In the search for low-cost color displays that do not drain a computer’s battery, the polymer light-emitting electrochemical cell (LEC) may be the next answer to the problem, according to an international team of electrical engineers.

“The color-variable LEC can provide a solution to simple, low cost color displays,” Cheng Huang, graduate student in electrical engineering at Penn State told attendees today (Aug. 20) at the 224th American Chemical Society annual meeting in Boston.

Obstacles fall to feasibility of hybrid fuel cell vehicle

A series of obstacles fell before the onslaught of a Penn State engineering graduate class as they tackled and found solutions to all the barriers preventing development of a hybrid fuel cell automobile using hydrogen fuel cells and battery storage.

“The professors asked the class to solve the problem of hydrogen odorization,” says Jamie Weston, graduate student in energy and geoenvironmental engineering. “We quickly came up with a solution and, took the rest of the course to develop our so
