Guiding Nanowire Growth for Self-Integrated Circuits

Those scientists working with tiny components in nanoelectronics say that the nano-components are so small that arranging them with external tools is impossible. Their only solution is to create the proper conditions for them to assemble themselves. Previously, researchers had developed methods for growing semiconductor nanowires vertically on a surface, but the structures were short and disorganized. After growing, these nanowires must be "harvested" and aligned horizontally so that they can be integrated into electric circuits.

Wireless Body Area Networks for Health Monitoring

A wireless personal health monitoring system using smartphones to upload data could revolutionize US healthcare. Faculty in the departments of electrical and computer engineering are leading research in mHealth at The University of Alabama in Huntsville. mHealth capitalizes on what Dr. Emil Jovanov, associate dean for graduate education and research in the College of Engineering, calls “major revolutions” in computer informatics, smartphones, and energy-efficient and miniaturized electronics and sensors. It can provide health information to the patient directly, to the physician via the Internet, and to researchers as aggregated databases.

Tips for Selecting Insulating Materials for Medical Electronics

Insulating and jacketing material options for wire and cable are innumerable, even if the field is narrowed to those with some qualification for use in medical electronics. Material selection for medical electronics is a complicated decision that begins with defining “qualification” and “medical”. Device manufacturers rely on a combination of inhouse experiences, cable suppliers, testing laboratories, consulting services, standards, guidance documents, and other publications. Their requirements for new devices may be defined strictly by the FDA, or may further incorporate application, market, or manufacturer preferences. For example, there are a great number of materials that will meet FDA requirements for surface contact patient monitoring cable materials, but a flexible and highly durable, silky-textured, cost competitive material may be preferred by the user. A specification may also call for a higher level of biocompatibility than is strictly required by the FDA. This may be the result of existing qualifications obtained with those materials, or it may be an over-specification that should be explored.
