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.

Electronics Thin Enough to Wrap Around Single Hair
Posted in Electronic Components, Electronics, Implants & Prosthetics, Medical, Patient Monitoring, Diagnostics, News, MDB on Friday, 10 January 2014
Researchers at ETH Zurich, Switzerland, a leading technology university, say they have developed electronic components that are so thin and flexible they can even be wrapped around a single hair without damaging the electronics. This may open up new possibilities for ultra-thin, transparent sensors, including to create smart contact lenses, which could be used to measure intraocular pressure to test for glaucoma, among other uses. The new thin-film transistors adhere to a wide range of surfaces and adapt perfectly, they say.
