“…While the frequency influenced the number of plasma discharges, the voltage amplitude determined the level of energy per pulse. Similar to Jiang et al (2013), the energy per pulse of the prototype, calculated from the Lissajous figure in Figures 8 and 9, was directly proportional to the applied voltage amplitude. More energy was injected into the gas to generate plasma discharge when a higher voltage amplitude was applied (Khatun et al, 2008).…”

“…More energy was injected into the gas to generate plasma discharge when a higher voltage amplitude was applied (Khatun et al, 2008). This induced a more uniform and intense surface discharge (Jiang et al, 2013). When the voltage amplitudes were the same, such as 4.9 kV at 25 and 30 kHz, more frequency-excitation created a larger mean-power (Khatun et al, 2009).…”

“…The mean power consumption was calculated by multiplying the energy of each cycle by the source frequency (Mahoney et al, 2010). The charge-voltage Lissajous figure is a standard method for the electrical diagnostics of DBD discharges (Jiang et al, 2013). All results were recorded by Agilent InfiniiVision DSO-X-2002A oscilloscopes.…”

Dielectric barrier discharge (DBD) plasma in air, a kind of non-thermal plasma, can disinfect the surface of a wound and enhance blood clotting without tissue damage. The purpose of this study was to design a prototype of a new, easily portable, DBD plasma device for first aid. In our prototype, the plasma discharge could be adjusted by changing frequency and using the pulse width modulation (PWM) function from a microcontroller. An electrode, coupled with the surface micro discharge (SMD) technique, reduced current leakage passing through the body. While the Lissajous standard method was utilized to measure the energy consumption per cycle, the optical emission spectroscopy approach analyzed the elements of plasma generation in ambient air. The prototype was convenient to carry and the amount of plasma discharge (containing the activated species O, OH, O 2 -, O 3 , N 2 , N 2 +) was easily varied to affect microorganisms and tissue.

“…In our previous works [8,9,11], these two spikes were discussed by calculation. Generally, the measured total discharge current can be divided into displacement current and conduction current, and the effect of the displacement current should be taken into account in a fast-pulsed discharge [11,14].…”

“…There are also some calculations and simulations to reveal the influence of grounded electrode's width on the characteristics of surface DBD [6,7], but experimental results are very limited. Based on our previous works [8][9][10][11][12], surface DBDs with different grounded electrode's widths in open air were produced in this paper, and electrical characteristics such as voltage, current and transported charges were shown and discussed.…”

Surface dielectric barrier discharges with five different grounded electrode's widths are produced in order to investigate the effect of grounded electrode's width on electrical characteristics. The electrical parameters including applied voltage, total discharge current and transported charges are measured and calculated, respectively. Results show that the total discharge current has two obvious spikes. The first current spike of the total current has a peak which results in some fluctuations of transported charges in V-Q Lissajous figures, but the peak of the first current spike hardly changes with the electrode's width. The second spike peak value increases with the electrode's width, and reaches its maximum at an optimum width. All the V-Q loops at different electrode's widths are "almond-shape", and the transported charges and energy per pulse increase with the electrode's width. The main plasma action area increases with the electrode's width, but keeps relatively constant when the grounded electrode's width is larger than the optimum width. In addition, the grounded electrode's width has no obvious influence on the plasma light intensity.

Dielectric barrier discharge (DBD) plasma actuators are simple electrohydrodynamic devices, which are able to provide effective aerodynamic control. One of the main components of these devices is the thin dielectric layer, which allows to separate and prevent the arc between the high‐voltage electrodes. Different materials can be used as dielectric layer to reduce the power consumption or boost the flow controlling effect of the actuators. In this context, this report presents a comparative study of two commercial polyimides, Kapton and Cirlex, used as dielectric layer of surface DBD plasma actuators. The electrical, dielectric, mechanical, electromechanical, and thermal properties were obtained to evaluate overall performance. It was verified that Cirlex (8.3 W) consumes less power than Kapton (21.3 W) to generate higher induced flow velocity of ≈3.4 m/s for an input voltage of 11 kVpp and 24 kHz. During one AC cycle at 11 kVpp the charge transferred for Cirlex (70 nC) is lower than for Kapton (100 nC), as well as the dielectric breakdown voltage to ignite the plasma discharge, 1.5 and 2.2 kVpp, respectively. The Cirlex DBD presents a higher voltage operation limit (at least 14 kVpp) and a more regular plasma discharge, which results in a more homogenous thermal profile and temperature distribution during its operation. The Cirlex actuator delivered higher mechanical power (6.2 mW) and achieved higher electromechanical efficiency (0.004%). The polyimide Cirlex proved to be a suitable alternative for Kapton to fabricate DBD plasma actuators for flow control with improved performance.
