Title: The Innovative Contributions of Raymond Poirier

Introduction

Raymond Poirier is a notable inventor based in Paris, France. He has made significant contributions to the field of electrical engineering, particularly in the development of advanced electret technologies. With a total of 4 patents to his name, Poirier's work showcases his commitment to innovation and excellence.

Latest Patents

One of Poirier's latest patents is a monolithic structure for storing electrical charges. This electret consists of a conductive electrode embedded in insulating materials, which provides a much higher capacity compared to conventional electrets that utilize a dielectric storage member. The manufacturing process allows for integration with an integrated circuit on its substrate. An electrolytic process is employed for charging the electret, which can be facilitated through an opening in the upper insulating layer. The metal electrode can be oxidized by anodic oxidation, enhancing the lifetime of the electret through the protective oxide layer.

Another significant patent is a display system using low energy electrons. This system utilizes electrons produced in the discharge of gases, specifically plasma. The design features a matrix of cells, each containing a cathode and a glass block that houses a plasma of helium. An assembly of an anode and a luminophore support is separated by an insulator, while a grid wire coated with an insulator serves as a control electrode and storage element. The electrons from the plasma can either excite or not excite the luminophore, depending on the potential applied to the grid.
