Self-Charging Power Cell for Small Devices

A hybrid power cell uses a new technique for electrical charge conversion and storage.

Scientists at Georgia Tech say that they have developed a new self-charging power cell technology that directly converts mechanical energy to chemical energy. Then, the power is stored until it is needed to generate electricity. This hybrid generator- storage cell utilizes mechanical energy more efficiently than systems using separate generators and batteries, they say.

Technology Highlights from 2013 International CES

The 2013 International CES came to Las Vegas once again, and January’s consumer technology trade show had plenty of innovative gadgets, from 27-inch ‘table PCs’ to ‘smart forks’ that slow down speedy eaters. Here are just a few devices that caught our attention at this year’s Consumer Electronics Show.

Users of the Tobii Technology REX, a USB-connected peripheral, may want to be careful about rolling their eyes. REX, a device that can be placed on the base of a computer screen, relies on eye positioning for navigation, page management, and access to other screen content. The mouse can still be used while the eye-tracker handles movements.

Integrating Electrical Systems into 3D Mechanical Models

Real-time integration of 2D schematics and 3D models allows mechanical and electrical teams to better collaborate and deliver more accurate designs.

Product development teams are under increasing pressure to engineer more complex products that combine numerous electrical systems within a single design, including visual interfaces, power systems, logic controllers, complex wiring and harnesses. Simplifying the design of these electro-mechanical systems using intelligent design tools, and a shared, comprehensive parts database, medical device designers are able to achieve significant cost savings. These savings are multiplied when this electrical design work is done in perfect synchronization with the mechanical and industrial design teams using a shared data model.

VA Developing New Heat- Enhanced Pulse Ox Device

Probe improves accuracy in reading blood oxygen saturation levels in patients who are harder to read due to low core temperature.

Pulse oximetry has gained widespread clinical acceptance as a standard patient vital sign measurement because it can give clinicians an early warning of low arterial blood oxygen saturation levels, or hypoxemia. Conventional pulse oximetry is subject to technological limitations that reduce its effectiveness and the quality of patient care. To mitigate the limitations of current technologies, the U.S. Department of Veterans Affairs (VA) has developed a novel device that provides reliable pulse oximetry measurements of oxygen saturation and heart rate in patients with low body temperature due to vasoconstriction and low blood perfusion.

Flexible Sensors Offer View into Epileptic Seizures

Brain activity can be monitored and sampled using minimal amount of wires and electrodes and improving implantable devices.

Tapping into the human brain to understand its functions in daily life — as well as its malfunctions in illness — has long been a challenge for researchers. Mapping brain activity requires unwieldy, invasive arrays of electrodes and sensors that can damage tissue while only reading activity in a limited area. A team of researchers at the Polytechnic Institute of New York University (NYUPoly) partnering with researchers from the University of Pennsylvania and the University of Illinois at Urbana-Champaign, have devised a streamlined, minimally invasive brain interface that may yield new insights into the causes of brain diseases like epilepsy and could potentially lead to new implantable neuroprosthetic and diagnostic devices.

Biosensor May Improve Disease Detection

A new biosensor could rapidly and accurately detect early stage disease in very low concentrations.

A quick, inexpensive and highly sensitive test that identifies disease markers or other molecules in low-concentration solutions could be the result of a Cornell-developed nanomechanical biosensor, which could potentially help with early stage disease detection.
