Latest Patents

Ogiura's latest patents include a method of manufacturing an acceleration sensor. This innovative sensor features a piezoelectric element supported by frames that hold the ends of the element in place. The piezoelectric element is constructed by stacking an even number of piezoelectric layers, with a minimum of four layers. Electrodes are strategically placed between the layers and on both the front and back faces of the element. The design incorporates interlayer electrodes, including segmented and lead electrodes, which are alternately stacked with the piezoelectric layers. Notably, the middle interlayer electrode is a segmented type. The polarization of the piezoelectric layers is arranged so that when acceleration is applied, charge of the same polarity is extracted from the electrodes. Additionally, the center and end portions of each layer are polarized in opposite directions. Another patent describes a piezoelectric type acceleration sensor that is compact yet boasts high charge sensitivity and large static capacitance. This sensor also utilizes a laminate of more than three piezoelectric layers, with electrodes positioned between the layers and on the top and bottom surfaces.
