We've seen a couple interesting attempts to convert vibrations and sound into electricity, but the latest design from a team at the University of Southampton is the first we've come across that's designed to be attached to bridges, large buildings, and other structures. The sugar cube-sized generator, a smaller version of a design already commercially available, uses cantilever-mounted magnets to induce a current in a copper coil -- a use of magnets to generate electricity that doesn't violate any laws of thermodynamics, which is always appreciated. The team has successfully used the generator to power an accelerometer (pictured), and tests indicate that the unit can put out up to 46 microwatts of power -- enough to run a pacemaker off the vibrations of the heart itself. No word on commercial availability, but the team seems like they're ready to get shaking fairly soon.

It looks like the ability to grab a can of beans wasn't enough to satisfy those mad scientists at the University of Southampton, who promptly went back to work in the lab to create an even more dexterous and sensitive robotic hand, one that'll let its human controller (or eventual autonomous robot overlord) pick up delicate objects without having to worry about breaking or dropping them. The big advance here, as New Scientist reports, is a set of pressure sensors fitted onto each fingertip that automatically determine the correct amount of pressure to apply, as well as set of so-called "slip-detectors," which can detect even slight amounts of slippage and correct the grip before the object falls crashing to the floor. Eventually, the researchers hope amputees will be able to take advantage of the hand, even linking it directly to their brain. It the meantime, however, 'ol Grippy here will likely continue to defend its undefeated streak in the sport of nerd-machine arm wrestling.

Ok, so there's no wind in your hair or chance of an immediate fiery death, but a world speed record's a world speed record, and when it could also lead to better and cheaper cellphones and digital cameras, we're all ears. At least that's what could be coming down the pipe thanks to the speedy new transistors created by researchers at the University of Southampton. What's even better is that they've done it with just a simple modification to existing transistor technology, meaning it should be fairly easy to move it from the research stage to the production line. The speed gain was achieved by adding fluorine implants to the silicon layers of the transistor, making the transistor thinner and more effective, ultimately topping out at a speed of 110 GHz, leaving the previous record of 70 GHz in the nanoscopic dust.
