In 2016, UC Berkeley engineers demonstrated the first implanted, ultrasonic, neural dust sensors. Now, taking the next step, the smallest-volume wireless nerve stimulator was developed, called StimDust...

Even the smallest mechanical pumps have limitations, from the micro-fabrication techniques required to make them to the fact that there are limits on their size. A laser-driven photoacoustic microfluidic pump was...

Lithium-air batteries are poised to become the next replacement for currently used lithium-ion batteries that power electric vehicles, cell-phones, and computers....

Polymers are regularly used as thermal insulators and can even be used as thermal conductors to enable efficient heating or cooling. A new type of polymer was created that demonstrates...

Following severe trauma, patients may have tissue damage or open wounds that require reconstructive surgery using fasciocutaneous flaps. These flaps of tissue, which are taken from...

Today's lithium-ion batteries use cathodes (one of the two electrodes in a battery) made of a transition metal oxide. Batteries with cathodes made of sulfur are considered a...

Researchers have created technology that is 10 times more reliable than current methods of producing unclonable digital fingerprints that can be used to...

Researchers have created wearable technology to convert mechanical energy into electrical energy. It presents a step toward the practical realization of self-powered, human-integrated technologies.

Methanol is a key feedstock for the production of chemicals, some of which are used to make products such as plastics, plywood, and paints. Methanol also can fuel vehicles or be reformed to...

Accurately measuring semiconductor properties of materials in small volumes helps engineers determine the range of applications for which these materials may be suitable in the...

Whereas hydrogen fuel cells (e.g., proton exchange membrane (PEM) and other fuel cells) generate electricity from the chemical reaction between pure hydrogen and oxygen, direct carbon fuel cells...

A process for fabricating atom-thin processors can be used to produce at the nanoscale for smaller and faster semiconductors.

A system was developed that can remove radioactive cesium contamination from porous structures such as brick and concrete that are hard to clean, as well as contamination from...

Researchers have developed a hybrid transformer that has the benefit of a full planar transformer design but uses a wire-wound secondary winding to keep the parasitic winding capacitances lower. Alone, planar transformers...

A continuous-testing device was developed that samples sweat as effectively as blood but in a noninvasive way and over many hours. After examining the use of saliva, tears, and...

Researchers have created highly stretchable supercapacitors for powering wearable electronics that consist of crumpled carbon nanotube (CNT) forests. The supercapacitors demonstrated solid performance...

Innovators at NASA’s Glenn Research Center have developed a new means of avoiding and mitigating icing events for aircraft flying above 14,000 feet, dramatically improving aviation...

There is a need for high-volume material testing/qualification but industry and researchers are currently limited by commercially available testing devices. Most wear testers can only handle one...

Aircraft currently fly based on coarse estimations of environment and aircraft state. Real-time measurements are traditionally restricted to laboratory environments (e.g. wind tunnel) due to the size and...

In the polymer composites industry, cure cycles are typically developed from trial-and-error or a more effective processing science approach to reduce...

There are many different types of 3D printing technologies. The most familiar — inkjet — has been around for some 20 years. But until now, it has been difficult to...

For the millions of people every year who have or need medical devices implanted, an advancement in 3D printing technology could enable significantly quicker...

By capping liquids with graphene (an ultrathin sheet of pure carbon), researchers can easily image and analyze liquid interfaces and the surface of nanometer-scale objects...
