Title: David J Perduijn: Innovator in Piezoelectric Technology
Introduction
David J Perduijn is a notable inventor based in Eindhoven, Netherlands. He has made significant contributions to the field of piezoelectric devices, holding a total of 4 patents. His work focuses on enhancing the functionality and efficiency of piezoelectric technology, which has applications in various industries.
Latest Patents
One of his latest patents is a "Piezoelectric device with high, constant preload force." This invention comprises a number of polarizable ceramic plates stacked with intermediate metal plates that serve as electrodes. The stack is subjected to a large amount of preload by a preloading element, which has a relatively flat spring-force characteristic over the piezoelectric operating range. The device is designed with a cylindrical housing that features two sets of parallel pairs of slots, rotationally displaced by 90 degrees. The preloading force is applied to the stack by threaded end plugs, and the ceramic plates are polarized only after assembly and preloading.
Another significant patent is the "Method of manufacturing jet nozzle ducts, and ink jet printer comprising." This method utilizes two plates of piezoelectric material, where mutually parallel channels are formed on the first major surface of the first plate. Metal layers are provided on both major surfaces of both plates, and both plates are polarized by applying an electric voltage between these metal layers. The first major surface of the first plate and the first major surface of the second plate are covered with a layer of adhesive, and tubes are arranged in each channel. The two plates are then arranged one on the other in a registering manner, and the adhesive is subjected to a curing process.
