Electrical Stimulus Could Heal Chronic Wounds
Posted in Electronics, Medical, Drug Delivery & Fluid Handling, News, MDB on Monday, 10 March 2014
A team of scientists at the University of Cincinnati, OH, says that an electrical stimulus can promote the growth of blood vessels and help to speed healing in diabetic ulcers and other hard-to-heal chronic wounds. Their research examines the best stimulus parameters, such as frequency and magnitude, for successful therapy.

Understanding How Piezoelectrics Work
Posted in Electronics, Imaging, Medical, News, MDB on Tuesday, 18 February 2014
Piezoelectrics, which can change mechanical stress to electricity and back again, are widely used in many fields, including computer hard drives, medical ultrasound, and sonar. Even so, understanding exactly they work is less widespread. A team of researchers at the National Institute of Standards and Technology (NIST), Gaithersburg, MD, in collaboration with Simon Fraser University, BC, Canada, believes they've learned why one of the main classes of these materials, known as relaxors, behaves in distinctly different ways from the rest and exhibits the largest piezoelectric effect.

Self-Aligning Wires for Nanoelectronics
Posted in Electronic Components, Electronics, Medical, Nanotechnology, News, MDB on Friday, 07 February 2014
Miniaturization in microelectronics is beginning to reach its physical limits, say researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) Institute of Ion Beam Physics and Materials Research, who are seeking new methods for device fabrication. They have discovered that one method may be the DNA origami technique in which individual strands of the biomolecule self-assemble into arbitrarily shaped nanostructures.

New Material for Thin, Light-Weight Electronics
Posted in Electronics, Medical, News, MDB on Friday, 17 January 2014
Scientists from SLAC, Stanford University, and Lawrence Berkeley National Laboratory’s Advanced Light Source, grew sheets of an exotic material in a single atomic layer and measured its electronic structure for the first time. They discovered it’s a natural fit for making thin, flexible light-based electronics.
