A University of California, Berkeley (www.berkeley.edu) team, headed by physics professor Alex Zetti, has built a 500 nm electric motor—the world's smallest—from carbon nanotubes and silicon. The motor is the first device that allows external wires and a rotor. In this case, the rotor is between 100 to 300 nm long, while the carbon nanotube shaft to which it is attached is only a few atoms across, perhaps 5 to 10 nm, the team says. Applications might include optical switching, or the spinning rotor could be used to mix liquids in microfluidic devices, the team adds.
Truchard will be presented the award at the 2014 Golden Mousetrap Awards ceremony during the co-located events Pacific Design & Manufacturing, MD&M West, WestPack, PLASTEC West, Electronics West, ATX West, and AeroCon.
In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
