Cubecell Capsule wake up on motion / low level vibration

#1

I am looking into the easiest and lowest cost way to wake up the CubeCell from sleep mode with low level vibration or motion.
One way could be a simple vibration sensor (SW-18010P) that I have tried attached directly to the interrupt pin.This works but requires a heavy shock to trigger. Would need to add a comparator circuit to increase the sensitivity.
Does anyone know of any other cheap stand alone mechanical sensors that could work. (Normally Open )
Or another way may be using the MPU9250 or another accelerometer - Does anyone have code to do this?
Would need to keep < 10 uA.
Thanks
