Portability Is the Name of the Game

June 24, 2013 2:12 pm | by Sean Fenske, Editor-in-Chief, MDT | Mega Electronics, Inc., Analog Devices, Inc., Maxon Precision Motors, Inc. | Articles | Comments

Medical electronic devices are no longer a trend; they are the reality of today’s healthcare environment. Seemingly, the number of powered medical devices far exceeds their non-powered counterparts. Even devices that had traditionally not been powered, such as the stethoscope, are now either being replaced by more effective electronic devices or being updated with electronics to function more efficiently and, more simply, better.

Simulating Solutions for Molding Challenges

June 21, 2013 4:18 pm | by Tim Lankisch, Director of Engineering, CAE Services | CAE Services Corporation | Articles | Comments

Design and development of a medical device is an exacting process, to say the least, and it assumes even more complexity because it almost always extends across years that encompass multiple iterations of the device. As a result, small things that were satisfactory in the prototype and first production run can grow to be problems that must be solved as production volume rises.

Carbon Nanotube Harpoon Catches Individual Brain Cell Signals

June 21, 2013 9:32 am | by Ashley Yeager, Duke University | News | Comments

Neuroscientists may soon be modern-day harpooners, snaring individual brain-cell signals instead of whales with tiny spears made of carbon nanotubes. The new brain cell spear is a millimeter long, only a few nanometers wide and harnesses the superior electromechanical properties of carbon nanotubes to capture electrical signals from individual neurons.

Light and Nanoprobes Detect Early Signs of Infection

June 21, 2013 9:20 am | by Duke University | News | Comments

Duke University biomedical engineers and genome researchers have developed a proof-of-principle approach using light to detect infections before patients show symptoms. The approach was demonstrated in human samples, and researchers are now developing the technique for placement on a chip, which could provide fast, simple and reliable information about a patient.
