Rob, you're right. That photo really shows how small these things are. What's even more amazing is to then consider how tiny the actual machines are inside this chip (remembering that MEMS stands for micro-electromechanical systems). Tiny accelerometers like these, along with gyrometers, are what make possible the movements of the Japanese flying sphere I wrote about
Yes, I remember that the Japanese flying machine was a great story. The size of the accelerometer makes for a wide range of applications. Years ago, Deisgn News flew me out to Research Triangle to do a video interview with Motorola when they included an accelerometer in a phone. It was used for games and to shake the song list to the next song.
The inherent reliability of these thermal accelerometer due to the absence of moving parts makes them ideal for some designs. Not sure how much these devices will be limited as specialty components or if additional research will enable them to penetrate additional applications. Seems to be part of the challenge going forward.
Auto Crash and Rollover Sensing requires higher bandwidth due to the higher da/dt jerk content of crash signals. ESC requires < 1.0 g because lower amplitude and slower da/dt and less rapidly chaning forces are involved.
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.
