Heated gas acceleometers are more expensive than capacitive ones. Hence theie lack of populatiry in consumer products. You also don't gat the "tap detect" function because of the lower bandwidth.

Rob, I believe the MEMS accelerometer application had something to do with gauging patients' motion, such as during walking, but I don't recall the exact details.

MEMS are being used in surgical robots and computer assisted surgery, such as orthopedic tracking during a knee replacement.

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.

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.

Great article. Question: If the speed is insuffient for airbag applications, why is it sufficient for electronic stability control?

I didn't realize accelerometer were getting deployed into medical applications. Make sense. Do you recall what the applications were? Heart monitoring, perhaps.

I read recently that MEMS accelerometers and gyrometers are being used in wearable medical patient monitoring devices, which makes a lot of sense.

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.
