“…Microplasma is a type of dielectric barrier discharge nonthermal plasma and its driven voltage is around only 1 kV. This technology could be used as a replacement of conventional technologies for surface treatment of polymers, indoor air treatment, biomedical applications, or flow control [29][30][31][32].…”

Dielectric barrier discharge (DBD) plasma actuators are a technology which could replace conventional actuators due to their simple construction, lack of moving parts, and fast response. This type of actuator modifies the airflow due to electrohydrodynamic (EHD) force. The EHD phenomenon occurs due to the momentum transfer from charged species accelerated by an electric field to neutral molecules by collision. This chapter presents a study carried out to investigate experimentally and by numerical simulations a microscale plasma actuator. A microplasma requires a low discharge voltage to generate about 1 kV at atmospheric pressure. A multi-electrode microplasma actuator was used which allowed the electrodes to be energized at different potentials or waveforms, thus changing the direction of the flow. The modification of the flow at various time intervals was tracked by a high-speed camera. The numerical simulation was carried out using the Suzen-Huang model and the Navier-Stokes equations.

“…A 30-μm gap is obtained in between the electrodes and using a resin at periphery to fix them. Plasma was generated around the holes and in between the electrodes while the gas flowed through the holes and was processed by microplasma discharge [35][36][37]. The microplasma discharge started when applying a sinusoidal voltage with amplitude 400 V0 − p (0 to peak) and frequency 27 kHz in air using a neon transformer.…”

Dielectric barrier discharge microplasma is a nonthermal plasma discharge at atmospheric pressure which due to the micrometer size dielectric layer between the grounded and high-voltage energized electrodes enables to drive the device at less than 1 kV. Microplasma is an economical and ecological alternative for conventional technologies used for NOx removal, indoor air cleaning, surface treatment of polymers, biomedical applications such as transdermal drug delivery, or as an actuator. In this chapter, microplasma applications such as indoor air purification, skin treatment for drug delivery, particle removal, and flow control are presented.
