“…On the other hand, corona discharge has many beneficial applications in electrostatic precipitation, surface treatment, gas detection, biomedicine, generating charged aerosols, etc. [4][5][6][7][8][9][10][11][12][13][14] When applying direct current (DC) voltage and only one electrode generating a stronger electric field (unipolar corona), we can name it positive or negative corona discharge according to the polarity of the active electrode. [15] The negative corona discharge modes include pulsed mode, pulseless (glow) mode.…”

Trichel pulse is a kind of pulsed mode in negative DC corona discharge, which has attracted significant attention because of its considerable applications in industry. Over eighty years, plenty of effort including simulations and experiments has been spent to reveal the ionization and quenching mechanisms of Trichel pulse. By revisiting and summarizing the basic characteristics and well-accepted ionization and quenching mechanisms, this review provides a basic understanding and the current status of Trichel pulse.

“…In this study, we have chosen a corona discharge as the alternative ion-generation method. Note that another kind of corona-based smoke sensor has been proposed [6] for which the discharge is triggered by smoke instead of being stopped by smoke.…”

Ionization smoke sensors are among the best smoke sensors; however, the little radioactive source they include is no longer desirable since it makes recycling more complicated. In this paper, we discuss an electrostatic system in which a corona discharge is used to generate the ions needed for smoke detection. We show how the velocity of ions is reduced in our system for a better interaction between smoke and drifting ions. The influence of smoke, temperature and moisture is studied. It is shown that the proposed sensor has good sensitivity compared with conventional ionic and optical smoke sensors.

“…Various spectral bands provide different types of information, and information enhancement could be achieved by selective fusion of different spectral bands. Consider corona discharge and fire detection, which has recently gained considerable attention resulted in numerous applications in the military and civilian fields, such as rocket engine monitor, fire alarm, missile tail flame tracking, etc [5][6][7]. Corona discharge and fire have a radiation spectrum that includes solar blind ultraviolet (UV), visible (VIS), and infrared light [8].…”

Various spectral bands provide different types of information, and information enhancement could be achieved by selective fusion of different spectral bands. The fused solar-blind Ultraviolet (UV)/Visible (VIS) bi-spectral sensing and imaging can provide the precise location of UV targets in virtue of VIS background, which has been increasingly promoted. However, most reported UV/VIS bi-spectral photodetectors (PDs) only have one single channel towards a broadband spectrum of both UV and VIS light, which cannot distinguish two kinds of signals, hindering the image fusion of bi-spectral signals. This work demonstrates the solar-blind UV/VIS bi-spectral PD based on vertically stacking perovskite of MAPbI3 and ternary oxide of ZnGa2O4 with independent and distinct response toward solar-blind UV and VIS light in a single pixel. The PD exhibits excellent sensing properties with an Ion/Ioff ratio of >10^7 and 10^2, detectivity of >10^10 and 10^8 Jones, and response decay time of 90 μs and 16 ms for VIS and UV channels, respectively. The successful fusion of VIS and UV images suggests that our bi-spectral PD can be applied in the accurate identification of corona discharge and fire detection.
