I am a PhD student in Tokyo Institute of Technology. My research relates to triboluminescence properties observed via dropping test.
The challenging task is how to determine a magnitude of impact force in order to estimate the exerting stress on the specimen. A result from using a cantilever equipped with a strain gauge was unsatisfied, that is, the emission signal is not coherent with the gauge signal in aspect of time-frame. Thus, an accelerometer might be the answer to the conundrum.
Although this might be unorthodox, are there whether or not any (a) a conversion factor from the measured acceleration into the force or (b) a proof mass inside the structure of ADXL326 and ADXL377 since [F = m*a]??
I am looking forward to the reply. Thank you very much in advance.
