REMOTE NON-INVASIVE PARAMETER SENSING SYSTEM AND METHOD

摘要

A remote parameter sensing system is provide that includes a gel sensor, a light source, a detector and a controller 140. The gel sensor is in contact with a surface where the parameter is to be measured, and is preferably a gel that is embedded with a chemical that emits light 160 (via, for example, fluorescence) when it is excited by excitation light from the light source at an appropriate excitation frequency. The chemical properties of the gel sensor are such that at least one characteristic of the emission light (such as, for example, emission intensity) varies as a function of variations in the parameter being measured. The system is particularly suited for use as remote body temperature sensing system in incubators and radiant warmers for infant and neonatal care.
