Millimeter sized, wirelessly powered cardiac device

Stanford electrical engineers overturn existing models to demonstrate the feasibility of a millimeter-sized, wirelessly powered cardiac device. The findings could dramatically alter the scale of medical devices implanted in the human body.

Electrically conductive gel

The Jell-O-like material, from the labs of Stanford professors Yi Cui and Zhenan Bao, may have applications in areas as widespread as energy storage, medical sensors and biofuel cells.

Thomas Edison's battery given new life

Stanford University scientists have breathed new life into the nickel-iron battery, a rechargeable technology developed by Thomas Edison more than a century ago.

Unzipped carbon nanotubes could help energize fuel cells

Multi-walled carbon nanotubes riddled with defects and impurities on the outside could eventually replace some of the expensive platinum catalysts used in fuel cells and metal-air batteries.

New nanostructure keeps batteries going and going

A team of scientists has found a cleverly designed double-walled nanostructure that lasts more than 6,000 cycles, far more than needed by electric vehicles or mobile electronics.

Solar retinal implants may restore sight to the blind

Using tiny solar-panel-like cells surgically placed underneath the retina, scientists at the Stanford University School of Medicine have devised a system that may someday restore sight to people who have lost vision because of certain types of degenerative eye diseases.

Composite collaboration leads to faster plastic electronics

Prof. Aram Amassian's group collaborates with Imperial College scientists to develop faster organic thin-film transistors.

Engineers create piezoelectric graphene

Materials engineers at Stanford have described how they have engineered piezoelectrics into graphene, extending for the first time such fine physical control to the nanoscale.

The first fully stretchable OLED

Now engineers at the University of California, Los Angeles, have taken a step toward these handy electronics by creating the first fully stretchable organic light-emitting diode (OLED).

Medical device can propel itself through the bloodstream

An electrical engineer has demonstrated a tiny, wirelessly powered, self-propelled medical device capable of controlled motion through a fluid—blood more specifically.

Wireless power could revolutionize highway transportation

A Stanford University research team has designed a high-efficiency charging system that uses magnetic fields to wirelessly transmit large electric currents between metal coils placed several feet apart.

Liquid batteries could level the load

New results from an ongoing research program at MIT show a promising technology that could provide that long-sought way of leveling the load — at far lower cost and with greater longevity than previous methods.

Highways to wirelessly charge moving cars

A Stanford University research team has designed a high-efficiency charging system that uses magnetic fields to wirelessly transmit large electric currents between metal coils placed several feet apart. The long-term goal of the research is to develop an all-electric highway that wirelessly charges cars and trucks as they drive down the road.

Improvement of the electrical conductivity of organic semiconductors

By packing molecules closer together, chemical engineers at Stanford have dramatically improved the electrical conductivity of organic semiconductors. The advance could herald flexible electronics, more efficient solar panels, and perhaps even better television screens.

Palo Alto increases green initiatives

The city of Palo Alto is accelerating its green initiatives in a bid to cement its standing as a highly eco-friendly area according to a Palo Alto Online news report.

IDTechEx Printed Electronics USA 2011 award winners

The annual printed electronics award winners were announced at the IDTechEx Awards Dinner in Santa Clara, California. The awards recognize outstanding progress in the development and commercialization of printed electronics, an industry that produces a huge amount of technical innovation which will be used in many products.

Stanford researchers have used nanoparticles of a copper compound to develop a high-power battery electrode.

Nanoparticle electrode for batteries

Nanoparticle electrode for batteries could make large-scale power storage on the energy grid feasible, say Stanford researchers

Towards an everlasting super battery

Stanford researchers have developed part of that dream battery, a new electrode that employs crystalline nanoparticles of a copper compound. In laboratory tests, the electrode survived 40,000 cycles of charging and discharging, after which it could still be charged to more than 80 percent of its original charge capacity.
