Abstract
The drop impact measuring system has i) a plurality of bimorph-type acceleration sensor containing a plurality of free vibrating sections each of which has individual draw-out electrodes; ii) a switch section for selecting output from the bimorph-type acceleration sensors; iii) an amplifying circuit for amplifying a signal applied via the switch section from the acceleration sensors; and iv) a logic circuit for logically evaluating the output from the amplifying circuit and controlling the switch section according to the result acquired from the logical evaluation.
Claims3
A bimorph-type acceleration sensor element, which is used for a bimorph-type acceleration sensor, comprising i) a plurality of free vibrating sections having a both-ends-supported beam structure;
- and ii) draw-out electrodes for drawing out a signal generated in the free vibrating sections.
