Accelerometers in cars

Would it be possible to install an aftermarket 3-axis accelerometer (like the ADXL377) in a car in order to provide G-force data to EMS so they could better assess possible injuries?

If so, I realize car deformation and crumple zones would make it difficult to place the accelerometer(s) to accurately measure similar G's as the vehicle occupants. That having been said, is there any suggestions as where would be best to place a device?

  • Hi Bterry88,

    We may be Analog Devices, but we don't strictly make analog parts.  We do a lot with converters which have digital interfaces and our MEMS parts are no exception.

    I don't know if you need as high a g-range as the ADXL377, but Nitzan and NevadaMark can comment on that better than I.  As for parts with >100g range, there's only the ADXL193, ADXL180, and ADXL001 but they are only single-axis parts.  The ADXL180 is a digital output part wheras the other two are analog.  The ADXL377 might be the only option for such a high-g, 3-axis part, but it is not quite released yet.
