<p>PROBLEM TO BE SOLVED: To provide a piezoelectric acceleration sensor which is not sensitive to an acceleration disturbing shock in a short time even in the case of a minute mechanical structure. SOLUTION: This piezoelectric acceleration sensor has a piezoelectric strip 1 whose one end is supported, and the piezoelectric strip 1 is bent corresponding to acceleration and generates a piezoelectric voltage corresponding to it, and the voltage can be taken out through the contacts on both sides. Hereby, negative-feedback means 3, 4 are installed and damping force reverse to a bending motion caused by the acceleration is given to a piezoelectric element 1.</p> |
