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.
