MEMS particle sensor based on resonant frequency shifting ...

Oct 06, 2020· In this paper, we introduce a MEMS particle sensor based on the resonance frequency shift according to added particle mass. The actuation is driven by Aluminum nitride (AlN), and the total thickness is μm. A laser doppler vibrometer (LDV), an optical measuring instrument, was used to measure the resonance frequency of the sensor.

led How to calibrate an optical particle sensor (Mie ...

The scattering angle is approximately 90 degrees. A photodiode is located diagonally with respect to the sensor ( scatter angle approx. 90 degress) I am trying to find out how to calibrate my device with respect to particle size. I looked through commercial optical particle counters out there, and they don''t really explain how they are calibrated.
