Fire is indeed one of the major contributing factors to fatalities, property damage, and
economic disruption. A large number of fire incidents across the world cause devastation …

The progress on fire sensing technologies has been quite substantial in recent years due to
advancements in sensing, information, and communications technologies. In this paper, the …

A novel six-band dual circular polarization (CP) rectenna for ambient radio frequency (RF)
energy harvesting is presented. Due to the nonlinearity and complex input impedance of the …

This study proposes a low-cost and reliable smart fire alarm system that utilizes ultraviolet
(UV) detection technology with an aspherical lens to detect fires emitting photons in the 185 …

Detecting fires is of significance to guarantee the security of buildings and forests. However,
it is difficult to fast and accurately detect fire stages in complex environment because of the …

Video flame and smoke-based fire detection usually exhibit large variations in the feature of
color, texture, shapes, etc., caused by the complex environment. It is difficult to develop a …
