Three advanced plastics welding processes are used in a novel fuel cell based on electroconducting polymer and transition metals in an effort to avoid use of adhesives. “We are using orbital vibration to weld the different membranes (anode and cathode) producing the energy,” comments Didier Perret, sales manager of Branson Ultrasonics in Switzerland. “We are using advanced ultrasonic welding for several assembly operations (to replaces screw, glue or others). And finally we use the latest infrared laser technology GEN 3 to weld the fuel tank with a high safety level.”
Ford and Unifi, maker of Repreve, will gather and recycle 2 million plastic bottles at CES and other shows for conversion into the Repreve seat fabric used in the 2012 Focus EV.
Thanks to embedded electronics, medical devices are getting smaller and smarter than ever. Pacemakers and implantable defibrillators are now able to call physicians. MRIs, CT scanners, and ultrasound machines are gaining mobility. And the venerable Band-Aid may soon be able to detect illnesses ranging from fevers to heart arrhythmias. On February 21, join Design News senior editor Charles Murray for a wide-ranging discussion, "Embedded Angles for Medical Products," which will explore the latest developments in medical electronics. The discussion will examine advances in medical device technology and offer an inside look at the embedded electronics behind it.
