We seek information on MEMS accelerometers parameters and their availability.

An experiment has been tenatively approved for the Space Station regarding
structural dynamics. A team has been formed to recommend an accelerometer type
instrument for the measurement.

Therefore, we are interested in finding out about tri-axial designs of MEMS
accelerometers in regards to their performance in the below 100 milli-g range,
their resolution capability, noise floor, relative dynamic range capability and
operational performance in measurements below 10 Hz to near zero Hz. We are
interested in a MEMS type accelerometer in order to make as small an instrument
package as possible.

We are also interested in manufacturers who make such a device. We have begun
to try an find data on the ADI products but there seems to be a lack of data
and what seems to be a very long lead time (1 year) to obtain any devices to
test.

Any product information on any manufacturers devices that you have would be
greatly appreciated. We also seek contacts of persons who might have test data
on these type of devices.
