Chip Could Eliminate Need for Magnets in Imaging
Posted in Electronic Components, Board-Level Electronics, Electronics, Imaging, Medical, Diagnostics, News, MDB on Tuesday, 03 June 2014
Researchers at the National Institute of Standards and Technology (NIST), Gaithersburg, MD, say that they have built and demonstrated a chip-scale device that both produces and detects a specialized gas used in biomedical analysis and medical imaging. The new microfluidic chip produces polarized (or magnetized) xenon gas and then detects even the faintest magnetic signals from the gas.

‘Smart’ Peg Tests Palsy Patients’ Dexterity
Posted in Electronics, Rehabilitation & Physical Therapy, Medical, Diagnostics, News, MDB on Thursday, 29 May 2014
While it may look like a game board and users may find it fun to use, there is a serious intent behind a device created by engineering students at Rice University, Houston, TX, to test the abilities of cerebral palsy patients. The DeXcellence platform uses a small peg comfortable enough for a three-year-old to hold. But packed inside are enough electronics to tell a nearby computer, tablet, or other Bluetooth-enabled device of how the cylinder is moving in space.

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.

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.
