| Tiny, implantable medical device can propel itself through bloodstream Posted: 22 Feb 2012 06:42 AM PST For 50 years, scientists had searched for the secret to making tiny implantable devices that could travel through the bloodstream. Engineers have now demonstrated a wirelessly powered device that just may make the dream a reality.  |
| Posted: 22 Feb 2012 06:42 AM PST Nanowires -- microscopic fibers that can be "grown" in the lab -- are a hot research topic today, with a variety of potential applications including light-emitting diodes and sensors. Now, researchers has found a way of precisely controlling the width and composition of these tiny strands as they grow, making it possible to grow complex structures that are optimally designed for particular applications.  |
| Recharge your cell phone with a touch? New nanotechnology converts body heat into power Posted: 22 Feb 2012 06:29 AM PST Never get stranded with a dead cell phone again. A promising new technology called Power Felt, a thermoelectric device that converts body heat into an electrical current, soon could create enough juice to make another call simply by touching it.  |
