Wearable plasma-pads for healthcare applications: Plasma patch, plasma bandage, plasma socks, and plasma cap

Discharge Characteristics and Plasma Erosion of Various Dielectric Materials in the Dielectric Barrier Discharges

“…In the flexible films, the dielectric thickness is different for each sample; accordingly, the capacitance (C~K/T) of each sample was affected by the K and T values. flexible polymer films have been used to manufacture a flexible plasma pad that can be applied for the wearable DBDs, such as the patches, bands, hats, and socks [35,36]. In this study, the discharge properties of various dielectric materials with thin solid plates and thin flexible films were examined regarding the DBD devices, with an especial focus on the plasma-discharge plasma erosion on the dielectric surface.…”

“…The voltage and In Figure 2, with the various dielectric materials listed in Table 1, a dielectric-barrier surface discharge was investigated for the discharge properties, current voltage, and firing voltage. The DBD structure shown in Figure 1c-iii was chosen, which is proper for the bio-medical application of the wearable plasma devices [35,36]. The plasma erosion of the dielectric surface was also tested.…”

“…The gap distance is an essential parameter for the ignition along the discharge path between the metallic electrodes on the surface of the dielectric layer. Figures 5 and 6 with the various dielectric materials listed in Table 1 show the discharge mode and the current-voltage (I-V) characteristics, respectively, while the DBD structure of Figure 2 is applicable for the actual plasma pads [35,36].…”

“…In addition, since the film dielectric layer is made as thinly as possible, the discharge voltage could be reduced, and this is advantageous for the DBD-device fabrication. Recently, the flexible polymer films have been used to manufacture a flexible plasma pad that can be applied for the wearable DBDs, such as the patches, bands, hats, and socks [35,36].…”

Silicone-coated polyimide films deposited by surface dielectric barrier discharges

“…The focus of most plasma devices in biomedical applications has been the development of plasma jets formed through a gas injection [11][12][13][14] and floating electrode dielectric-barrier discharges (FE-DBDs) using a solid dielectric plate of thin quartz-glass [15][16][17]. Various types of wearable plasma devices have recently been presented, including a plasma pad, a plasma bandage, plasma socks, and a plasma cap [18,19], which use a thin flexible polyimide film for hybrid-type DBD. However, unlike conventional plasma jets or DBD devices, plasma pad has garnered attention due to the variety of potential applications and the convenience of them in wearable devices.…”
