Dielectric barrier discharge plasma actuators

YPlasma is a named commercial developer, while FACTS lists 24 companies overall. YPlasma develops thin DBD actuators for solid-state airflow and thermal management, and announced fanless cooling for NVIDIA Jetson in June 2026. Canon Inc. is a leading patent holder in the field, but patent ownership alone does not establish that a company manufactures or supplies actuators.

Xi'an Jiaotong University, University of Beira Interior and Chinese Academy of Sciences CAS are among the active research organizations. FACTS lists 38 recent documents for Xi'an Jiaotong University and 14 for University of Beira Interior; CAS has 13. Their work spans flow-separation control, actuator durability, pulse behavior and closed-loop control.

FACTS records $2,840,835 in grants across 4 awards since 2020. It also reports 5 funding rounds totaling $116,617,509. These indicators should be read separately: the rounds data includes organizations such as University of Nottingham and Aalto University, and does not by itself show that all funds were dedicated to DBD actuator development.

Canon Inc. leads the listed patent holders with 7 patents. Nissan Motor Co. and TOMI Environmental Solutions have 2 each. The remaining listed holders have 1 apiece, including Polytechnic University of Catalonia and University of Antwerp. Patent counts indicate recorded ownership, not necessarily current product activity or commercial supply.

Patent activity is declining in the current window: FACTS records 17 patents over 24 months and patent growth of -58.3%. Publication activity is moving in the other direction, with 379 publications last year and growth of 20.3%. The contrast suggests continued research interest alongside a slower pace of patenting.

DBD plasma actuation is an established research technology with emerging demonstrations beyond laboratory setups. Recent work includes a flight demonstration of closed-loop drag reduction in July 2026 and fanless cooling unveiled by YPlasma in June 2026. However, durability, thermal behavior, power efficiency and repeatable performance in real operating conditions remain important engineering challenges.

September 2026 studies examined AC-DBD in-flight drag reduction and flow separation control on UAV propellers. In August 2026, University of TechnologyXian and Chinese Academy of Sciences CAS reported online reinforcement-learning control of slender-body vortices. Other recent directions include hybrid aluminum–copper electrodes for reducing thermal hot spots and composite laminates that combine structural, electrical and flow-control functions.

The main approaches are AC surface-discharge actuators, nanosecond-pulsed actuators, plasma synthetic jets, sliding-discharge actuators, and segmented and array actuators. They differ in discharge waveform, geometry and the way they deliver momentum or heat to the flow. The choice depends on the control target, required response and constraints such as power, thermal load and system complexity.

China leads the listed country activity with 1,903 documents, or 42.2%. The United States follows with 620 documents, and Japan with 455. These figures indicate where documents are attributed, not necessarily where all research, manufacturing or commercial deployment takes place.

Airfoil separation and lift control is the largest named application, with 117 documents in FACTS. Other applications include aircraft aerodynamic control, turbomachinery and combustion, aeroacoustic control, and electronics thermal management. Recent studies also examine UAV propellers, road-vehicle drag reduction, aircraft anti-icing and fanless cooling for NVIDIA Jetson.
