Abstract: The present invention relates to an extinguishing composition and comprises an extinguishing material and a capsule containing the extinguishing material, and the extinguishing material comprises calcium bromide (CaBr2).

Abstract: There are provided a flame retardant element for suppressing flame propagation when a fire occurs during the use of a lithium secondary battery, thereby ensuring safety of the secondary battery while in use, a method for manufacturing the flame retardant element, and a secondary battery module and a secondary battery pack comprising the flame retardant element. The proposed flame retardant element is a composite pad having a stack of at least two polymer resin single layers including fire extinguishing materials having different fire extinguishing and flame retardant mechanisms, the composite pad includes a first polymer resin single layer and a second polymer resin single layer, and the first polymer resin single layer includes the fire extinguishing material which takes effect in a lower temperature range than the second polymer resin single layer.

Abstract: An extinguishing composition includes an extinguishing material and a capsule containing the extinguishing material. The extinguishing material includes calcium bromide. The extinguishing material may be in a capsule.

Abstract: An adhesive method for an optical fiber curvature sensor results in a sensor having improved sensitivity for measuring body motions such as motions of fingers, arms, or legs, and in particular that is capable of measuring both a curving direction and degree of curvature of a subject simultaneously, even for variable surface areas such as those of the waist or shoulders. The method is carried out by adhering an optical fiber to a subject in a curved state.

Abstract: The present invention relates to an optical fiber curvature sensor for measuring body motion and its adhesive method. More particularly, it relates to an optical fiber curvature sensor for measuring body motion and its adhesive method having an improved sensitivity for measuring body motions such as motions of fingers, arms, or legs, which is able to measure curving direction and curved degree of a subject simultaneously and applicable for subjects of which the surface areas are varying such as waist or shoulders, by adhering an optical fiber to a subject in curved-state.
