Title: Quanshui Zheng: Innovator in Graphite Slider Arrays and RF Switch Technology
Introduction
Quanshui Zheng is a prominent inventor based in Beijing, China. He has made significant contributions to the fields of manufacturing methods and radio frequency technology. With a total of 3 patents, Zheng's work showcases his innovative approach to solving complex engineering challenges.
Latest Patents
One of Zheng's latest patents is a manufacturing method for graphite slider arrays. This method introduces a grain structures examination step in the production process, ensuring that only one horizontal grain boundary exists within the graphite mesas. As a result, the sliders can slide away smoothly along this grain boundary, leading to uniform easy-slip surfaces and consistent thickness.
Another notable patent is the in-plane sliding parallel capacitive radio frequency (RF) switch. This device comprises a substrate, multiple drive components, an insulating layer, and a sliding component. By applying a drive voltage between the first and second drive components, the sliding component can create a large capacitance, effectively reflecting RF signals and cutting off transmission. Conversely, when the voltage is applied between the second and third drive components, the sliding component allows for minimal capacitance, enabling RF signal transmission with minimal loss.
