Electret: A Novel Solution for Emerging Dielectric Challenges
Description:
Overview of Technology
Method using existing dielectric material to solve dielectric challenges emerging with technological advancements
Background
As electronic circuitry becomes more compact, devices that utilize any level of voltage across conductive surfaces are susceptible to partial discharge activities. These high electric fields can be created by sharp edges or protrusions and can prematurely age or fail a device. The goal of this solution is to prevent this mode of failure by eliminating those electric fields.
Description of Technology
Researchers at Mississippi State are using an existing type of dielectric material in a novel way to effectively mitigate emerging challenges that come with technological advancements.
This method introduces electret layers around high-voltage surfaces to mitigate the undesired high electrical fields, space charge accumulation, and PD activities that cause material aging and failure. This method, unlike similar methods with these dielectric materials, can result in the total elimination of dielectric challenges instead of partial.
This method can be installed by placing electret layers on dielectric material surfaces, by spraying electret materials on top of the surfaces of interest, or by introducing electret films within a given system. These various ways of installation allow for this method to be more adaptable to the consumer.
Benefits
This method gives great development towards prolonging the life of dielectric materials which can increase resiliency, reduce repetitive spending, and generate a more permanent fix to the issues emerging with technological advancements.
Applications
The purpose of this method is to mitigate issues within this scope of dielectric materials.
This invention will help consumers to improve the resiliency and lifetime of emerging technologies that have high power density and operate under non-AC systems (DC and power electronics).
Opportunity
Mississippi State University currently seeks companies or researches that work with this kind of high-power density technology and operate under non-AC systems.
This method can be highly effective in industrial and military scenarios.
