(a) Measurement setup for testing of the stability of the sample between soft materials. (b) Measured values of the frequency shift of the sensor for 100 repeated tests at loading levels of 1.8 N and 2.5 N. (c) Statistical distribution for the 100 repeated tests under a loading force of 1.8 N. (d) Statistical distribution for the 100 repeated tests under a loading force of 2.5 N.
