Curious if anyone has found a USB transducer to measure vibration with REW?

I am looking to place a contact microphone on audio gear chassis, PCB, etc. and sweep in the audio room and look for resonances at audio frequencies. A USB accelerometer is expensive so curious if anyone has accomplished anything similar with a simple piezo? Maybe a piezo and a mini USB mic amp?

Not sure what to do about cal files though.
