Unexpected Discovery Leads to a Better Battery

An unexpected discovery has led to a rechargeable battery that's as inexpensive as conventional car batteries, but has a much higher energy density. The new battery could become a cost-effective, environmentally friendly alternative for storing renewable energy and supporting the power grid. The Department of Energy's Pacific Northwest National Laboratory (PNNL) identified this energy storage gem after realizing the new battery works in a different way than they had assumed.

Researchers Turn Urine into Power Source for Electronic Devices

A microbial fuel cell uses natural biological processes of ‘electric’ bacteria to turn organic matter, such as urine, into electricity. These fuel cells are efficient and relatively cheap to run, and produce nearly zero waste compared to other methods of electricity generation. Urine passes through the microbial fuel cell for the reaction to happen. From here, electricity is generated by the bacteria, and can then be stored or used to directly power electrical devices.

Graphene Layer Lets Solar Cells Generate Power When it Rains

Chinese researchers have introduced a new approach for making an all-weather solar cell that is triggered by both sunlight and raindrops. To convert solar energy to electricity, the team developed a highly efficient dye-sensitized solar cell. In order to allow rain to produce electricity as well, they coated this cell with a whisper-thin film of graphene.

Hermetic Feedthroughs Safeguard Mission-Critical Electronics

Experts specializing in electronics failure analysis can list a host of reasons for various malfunctions, but one of the most common causes is simple moisture. Because water and electronics do not mix well, several strategies exist to protect mission-critical components from moisture and condensation. One of the most successful methods of protecting key components from water hazards involves hermetically sealed electronics cavities—enabled by moisture-blocking component assemblies such as hermetic feedthrough technology.

Component Design with a Twist

Helixes in nature abound—from the formation of DNA, to the spiral of a seashell, to the tendril of a climbing vine. That is because the helical structure provides support for the curve through three-dimensional space. Taking a cue from nature, Fort Wayne Metals created its Helical Hollow Strand (HHS® Tube) with up to three layers to provide engineers with solutions to design problems that exceed the capabilities of conventional constructions.

Five-Fingered Robot Gets a Grip

Intricate tasks that require dexterous in-hand manipulation — rolling, pivoting, bending, and sensing friction — are a challenge for today's robots. A University of Washington team of computer scientists and engineers has built a robotic hand that performs dexterous manipulation and "learns" from its own experience. The five-fingered robot, for example, can spin a tube full of coffee beans without needing human direction.
