VIBRATION SENSOR PART AND VIBRATION SIGNAL EXTRACTION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide means for allowing vibration signals to be efficiently obtained by a vibration sensor.SOLUTION: A vibration sensor part comprises: a vibration sensor 10 including a vibration sensor material sandwiched between a positive electrode layer and a negative electrode layer; and signal amplification means 11 including an uneven surface. The uneven surface of the signal amplification means is arranged opposite to a surface of the vibration sensor material.SELECTED DRAWING: Figure 1
