Title: Innovator Hiroki Iwai: Pioneering External Force Detection
Introduction: Hiroki Iwai is a prominent inventor based in Saitama, Japan, recognized for his significant contributions to the field of piezoelectric technology. With 14 patents to his name, he has made substantial strides in developing methods and devices that enhance the detection of external forces applied to piezoelectric plates.
Latest Patents: Iwai's latest innovations include a range of patents focused on external force detection methods and devices. A key invention involves a technique for accurately detecting external force applied to a piezoelectric plate. This advanced method employs a cantilever-supported crystal plate that is housed within a container. Excitation electrodes are strategically located on both the upper and lower faces of the crystal plate, with a movable electrode on the lower face and a fixed electrode positioned at the bottom of the container. The oscillation circuit connects the excitation electrode on the upper face and the fixed electrode. When external force is applied, the bending of the crystal plate changes the capacitance between the movable and fixed electrodes, which in turn alters the oscillation frequency of the crystal plate.
Another significant development by Iwai includes an external force detecting device that similarly utilizes a cantilever-supported piezoelectric piece. This device ensures precision in detecting external forces through a crystal piece that bends in response to applied force, leading to changes in capacitance and oscillation frequency.
Career Highlights: Iwai has devoted much of his career to the advancement of piezoelectric technology, particularly through his role at Nihon Dempa Kogyo Co., Ltd. His extensive patent portfolio reflects his dedication to innovation in this field, as he continuously seeks to refine and enhance detection methods that are critical for various applications.
