Super Thin Material Acts Like a Switch
Posted in Electronics, Medical, News, MDB on Thursday, 24 April 2014
 A team of researchers from Cornell University, Ithaca, NY, and Brookhaven National Laboratory, Upton, NY, have demonstrated how to switch a particular transition metal oxide, a lanthanum nickelate (LaNiO3), from a metal to an insulator by making the material less than a nanometer thick.

An interdisciplinary research team from Northwestern University, Evanston, IL, the University of Illinois, Urbana-Champaign, and the University of Arizona, Tucson, has developed a flexible medical implant that harvests energy from the beating heart, which, they say, could be used to power pacemakers, defibrillators, and heart-rate monitors naturally and reliably and reduce or eliminate the need for batteries.

Epidural Stimulation Could Combat Paralysis
Posted in Electronics, Rehabilitation & Physical Therapy, Medical, Patient Monitoring, Orthopedics, News, MDB on Thursday, 10 April 2014
Exciting news was reported by an international team of life scientists at the University of Louisville, KY; UCLA, Los Angeles, CA; and the Pavlov Institute of Physiology, Saint Petersburg, Russia; who say that epidural electrical stimulation of the spinal cord has allowed four men who’ve been paralyzed for years the ability to move their legs. This study was published in the medical journal, Brain.

An international team of engineers from Penn state University, University Park, PA, and King Abdullah University of Science and Technology, Saudi Arabia, have discovered that saliva-powered micro-sized microbial fuel cells can produce minute amounts of energy—enough to run on-chip applications, they say. This technology may be enough to fuel glucose monitoring for diabetics.

Transient Electronics Dissolve When Triggered

An Iowa State research team led by Reza Montazami is developing "transient materials" and "transient electronics" that can quickly and completely melt away when a trigger is activated. The development could mean that one day you might be able to send out a signal to destroy a lost credit card.

To demonstrate that potential, Montazami played a video showing a blue light-emitting diode mounted on a clear polymer composite base with the electrical leads embedded inside. After a drop of water, the base and wiring began to melt away.

As the technology develops, Montazami sees more and more potential for the commercial application of transient materials. A medical device, once its job is done, could harmlessly melt away inside a person’s body. A military device could collect and send its data and then disappear, leaving no trace of an intelligence mission. An environmental sensor could collect climate information, then wash away in the rain.
