Document Type and Number:
Japanese Patent JP6764928
Kind Code:
B2
Abstract:
In the vibration detecting method, vibration sensor, vibration detecting device, vibration detecting program and vibration detecting system according to the present invention: a vibration input surface portion and a vibration suppression surface portion are established on a piezoelectric layer; vibrations of a vibrating body are input into the vibration input surface portion; a vibration absorbing body which absorbs the vibrations of the vibrating body is installed to suppress the vibrations entering the vibration suppression surface portion; and a piezoelectric output is extracted from one or a plurality of electrode pairs sandwiching the piezoelectric layer. By this means it is possible to achieve a further reduction in size and weight, and to perform vibration detection with high and stable sensitivity. Further, a high degree of freedom for installation on a vibrating body is afforded, stable vibration detection can be performed without being affected by a vibration detecting surface of the vibrating body, and the reliability of vibration detection can be enhanced.
