I've spoken to many engineers who didn't know how important selecting the right accelerometer was for ensuring accurate results. There are three main accelerometer types:
- capacitive MEMS
- piezoresistive
- piezoelectric
I've written a quick overview of these accelerometer types along with a table that can help determine the best accelerometer type for your testing application. Here's the link if interested: http://blog.mide.com/accelerometer-selection
