New Approach to Graphene Electronics

Graphene has been touted as the next silicon, but it is too conductive to be used in computer chips. A University of Manchester team led by Nobel laureates Professor Andre Geim and Professor Konstantin Novoselov has literally opened a third dimension in graphene research.

Self-Healing Electronics Could Reduce Waste

When one circuit within an integrated chip cracks or fails, the whole chip – or even the whole device – is a loss. University of Illinois engineers have now developed a self-healing system that restores electrical conductivity to a cracked circuit in less time than it takes to blink.

Efficient Method for Creating Flexible, Transparent Electrodes

As the market for liquid crystal displays and other electronics continues to drive up the price of indium — the material used to make the indium tin oxide (ITO) transparent electrodes in these devices — scientists have been searching for a less costly and more dynamic alternative, particularly for use in future flexible electronics.

Electronics Category Winner

iPecs

Michael Leydet,
College Park Industries, Fraser, MI

The College Park Industries iPecs® (In telligent Prosthetic Endo-Skeletal Com ponent System) is a medical research device that will provide researchers with a tool to accurately measure human locomotion or gait parameters on users of lower limb prostheses. The iPecs measures forces and torsionmoments that can then be wirelessly transmitted in real time to a PC interface. This wireless capability of the iPecs will, for the first time, allow environmentally unencumbered re search to be conducted outside of the laboratory, providing insight into what a prosthesis user experiences on a daily basis.

Thermal Management Solutions for Medical Applications

Thermoelectric Assemblies (TEAs) offer precise temperature control for applications with tight space constraints and low weight requirements.

Thermal management of medical electronic devices and systems is now more challenging. Power densities continue to increase while product form factors continue to shrink. Simple thermal management solutions, such as passive cooling (adding a fan and heat sink), are no longer typically viable to meet required performance and reliability specifications. In today’s complex medical operating environment, Thermo electric Assemblies (TEAs) are necessary to provide precise temperature control via cooling and heating in a variety of modular platforms.

Protecting Signal Integrity in Industrial Environments

Data communications in industrial environments can present special problems. Lines must be run over long distances, often ranging from thousands of feet to several miles, indoors and outdoors, from the field to the control room, and from building to building. These data communication systems must be able to function in the presence of electrical transients, and noise, ground loops, and surges from nearby lightning strikes.

Electrocardiography (ECG) Necklace

Wearable monitoring system uses an ultra-low-power application-specific integrated circuit and a beat-to-beat detection algorithm to measure cardiac activity.

Integrated wearable monitoring systems based on body area networks (BANs) enable continuous, reliable, and long-term monitoring of physio- and biological signals on the move, leading to wearable health solutions for next-generation healthcare, wellness, and lifestyle. An electrocardiography (ECG) necklace has been developed to target the simultaneous monitoring of cardiac and physical activity in everyday life situations.

Experimental Walking Assist Device With Body Weight Support System

This technology is designed for users who, though capable of walking on their own, would benefit from a reduction of load on their leg muscles and joints.

An experimental walking assist device has been developed to help support body weight and reduce the load on the user’s legs while walking, going up and down stairs, and in a semi-crouching position. The device reduces the load on leg muscles and joints (in the hip, knees, and ankles) by supporting a portion of the person’s body weight. It features a simple structure consisting of seat, frame, and shoes, and the user can put it on by simply wearing the shoes and lifting the seat into position. Moreover, a mechanism that directs the assisting force toward the user’s center of gravity and the ability to control the assist force in concert with the movement of the legs make it possible for the device to provide natural assistance in various postures and motions.

Design Considerations for Battery Connectors

As medical devices become more portable and miniaturized, their power connections must evolve to meet these demands.

The future of batteries, like that of so many medical devices they power, is clearly toward smaller, lighter, and more powerful models. Developing concurrently with these new battery designs are battery connectors. As battery connection devices evolve, they have to meet a number of challenges, including: rapid growth of designs; rugged construction; high-density packaging; manufacturing costs; and environmental concerns.
