The Create the Future Design Contest was launched 16 years ago by Tech Briefs Media Group (publishers of Tech Briefs magazine) to help stimulate and reward engineering innovation. Since then, the annual contest has drawn more than 14,000 product design ideas from engineers, students, and...

Both the aerospace and automotive industries depend increasingly on electrochemical energy storage. Reduction in mass, increase in energy, and increase in power can benefit both of these areas dramatically. Supercapacitors are currently under consideration for use in both...

Lithium-ion (Li-ion) cells are increasingly used in high-voltage and high-capacity modules. The Li-ion chemistry has the highest energy density of all rechargeable battery chemistries, but associated with that energy is the issue of catastrophic thermal runaway with a fire. With...

Cornell University scientists have developed an oxygen-assisted aluminum/carbon dioxide power cell that uses electrochemical reactions to both sequester the carbon dioxide and produce electricity.

Common solar energy systems today are unable to use the generated energy at night or in cloudy conditions. A University of Texas at Arlington materials science and engineering team has developed a new energy cell that stores large-scale solar energy even when it is dark.

A Binghamton engineer, Seokheun "Sean" Choi, developed an inexpensive, bacteria-powered battery made from paper. Using a drop of bacteria-containing liquid, the battery generates power from microbial respiration and delivers enough energy to run a paper-based biosensor.

MIT Media Laboratory researchers are developing a wearable device that turns the user’s thumbnail into a miniature wireless track pad.

UCLA researchers have successfully combined two nanomaterials to create a new energy storage medium that combines the best qualities of batteries and supercapacitors.
