a Consideration of the Laplace pressure and sandblasting treatment as a spring and for reducing the damping effect, respectively. b Setup for oscillating the device. c Experimental result: 13 Hz of natural vibration frequency with a sandblasting-treated device (with a small damping) (8 μL of LM, oscillation frequency: 2 Hz). d Application of the device to the base excitation model. e Mathematical result from the base excitation model
