Functional Electrical Stimulation Technique May Improve Neural Implants

Researchers improve the efficiency of devices that stimulate damaged nerves, reducing potential side effects. Electrical implants that shut down excessive activity in brain cells hold great potential for treating epilepsy and chronic pain. Likewise, devices that enhance neurons’ activity may help restore function to people with nerve damage.

Boosting Nanowires for Better Batteries and Solar Cells

Stanford University engineers have found a novel method for "decorating" nanowires with chains of tiny particles to increase their electrical and catalytic performance. The technique is simpler and faster than earlier methods and could lead to better lithium-ion batteries, more efficient thin-film solar cells, and improved catalysts that yield new synthetic fuels.

Tailoring Metal Oxides for Green Technological Applications

Harnessing solar energy can be as simple as tuning the optical and electronic properties of metal oxides at the atomic level by making an artificial crystal or super-lattice ‘sandwich.’ "Metal oxides can be tailored to meet all sorts of needs, which is good news for technological applications, specifically in energy generation and flat screen displays,” said Louis Piper, assistant professor of physics at Binghamton University.

Boosting Energy Efficiency of Multi-Hop Wireless Networks

Multi-hop wireless networks can provide data access for large and unconventional spaces, but they face significant limits on the amount of data they can transmit. North Carolina State University researchers have developed a more efficient data transmission approach that can boost the amount of data the networks can transmit by 20 to 80 percent.

New Thermal Management Strategies for Medical Devices

Heat pipes and vapor chambers are being utilized to address challenging thermal management requirements. In an increasing number of medical device applications, thermal issues limit the overall performance and reliability of the system. Basic thermal management strategies such as liquid cold plates, air cooled heat sinks, and thermal interface materials are becoming insufficient as stand-alone solutions. In many new medical applications, implementation of advanced thermal technologies such as heat pipes and vapor chambers are becoming an integral part of the thermal management solution. These technologies offer excellent heat transfer and heat spreading performance. Furthermore, they are passive (no energy, no moving parts), quiet, and reliable. Several medical devices, such as powered surgical forceps, skin/tissue contacting devices, and polymerase chain reaction (PCR)/thermocyclers already use these technologies, and more applications are emerging. A discussion of heat pipe and vapor chamber operation and selected medical device applications follows.
