Abstract
The present disclosure provides a hydrogen peroxide sterilization sensor and method of use. The sensor includes: at least one thermal indicator component independently selected from an electronic thermal sensor, an irreversible temperature indicator, and a heat-shrinkable film; a reactant-functional porous sorbent in thermal contact (which may or may not be direct physical contact) with the at least one thermal indicator component; and a reactant comprising a material that reacts exothermically with hydrogen peroxide. The reactant is impregnated in the porous sorbent. The method includes: providing a hydrogen peroxide sterilization sensor; allowing hydrogen peroxide to contact the reactant to generate thermal energy sufficient to cause a response from the at least one thermal indicator component; and detecting that conditions for the hydrogen peroxide sterilization have been met.
