Managing Risk in Medical Connectors

Every day, medical device manufacturers are getting better and better at managing risk. They know they have to. Changes have been introduced into international regulatory schemes that impact device design all the way down to the component level. Perhaps the most fundamental and wide-ranging of these has been the emergence and adoption of formal risk management methodologies as an integral part of the regulatory process.

Transistor for High-Performance Devices at Low Voltage

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.
