Microdischarges

Microdischarges are a type of electrical discharge that occurs across very small gaps, typically in the micrometer to millimeter range. These discharges are characterized by their short duration, low power consumption, and high electric field gradients. They are often generated in gases at atmospheric or near-atmospheric pressures. Microdischarges can exhibit various physical phenomena, including plasma formation, ionization, and the emission of light and heat. Their behavior is influenced by factors such as gas type, gap distance, electrode material, and applied voltage.

The study of microdischarges is driven by their potential for a wide range of applications. These include surface treatment, sterilization, ozone generation, environmental remediation, and ignition systems. The compact size and low energy requirements of microdischarges make them suitable for integration into portable devices and microfluidic systems. Research in this field focuses on understanding the fundamental physics governing their behavior, developing new electrode geometries, and optimizing their performance for specific applications. Factors such as the formation of microplasmas, filamentary structures, and their interaction with surrounding materials are active areas of investigation.
