Transistor for High-Performance Devices at Low Voltage
Posted in Electronic Components, Power Supplies, Thermal Management, Electronics, Power Management, Implants & Prosthetics, Medical, Patient Monitoring, News, MDB on Tuesday, 17 December 2013
A team of scientists at Penn State, University Park, PA, say that a new type of transistor could make fast, low-power computing devices possible for energy-constrained applications such as implantable medical electronics, smart sensor networks, and ultra-mobile computing. Called a near broken-gap tunnel field effect transistor (TFET), the new device uses the quantum mechanical tunneling of electrons through an ultrathin energy barrier to provide high current at low voltage.

Thermally Optimized Medical Devices Improve Patient Outcomes
Posted in Features, Manufacturing & Prototyping, Electronics, Electronic Components, Thermal Management, Medical, MDB on Tuesday, 12 November 2013
Today’s medical device and equipment designs are highly influenced by continuous technological advances that affect their size, power consumption, and communication capabilities. But patient safety and comfort are also critical considerations, forcing designers to balance the demands of new technology with the demands of new forms of patient care. From addressing industry-wide concerns over bioburden to adhering to strict noise limitations and biocompatibility needs, the list of requirements is becoming increasingly long. In order to provide the best possible solutions, medical device designers need a working knowledge of the thermal management technologies available to them. Armed with a thorough understanding of both passive and active thermal management systems, including their components, benefits, and applications, designers can more effectively address all the needs of the medical industry.
