Abstract:
1. A sensor, for radiance based diagnostics, comprising a performing component and an adhering component, said performing component comprising: at least one detector for detecting rays reflected from within said tissue; wherein said adhering component comprises a sealable lower surface having a greater surface area than the surface area of the performing component, said sealable lower surface configured to surround and adhesively adhere to the upper surface of the performing component, the lower surface of said performing component extending beyond the lower sealable surface of the adhering component; wherein said performing component comprises means to block the detector from the radiance source so that rays emitted from the radiance source are unable to reach the detector through any other medium except reflected from the tissue; wherein the lower sealable surface of the adhering component is adhesively attachable to the tissue to form an indentation in the tissue, the surface area of said indentation corresponding to the lower surface of the performing component, said indentation preventing external light from being detected by said at least one detector; and wherein said sensor further comprises a controlling device capable of sensing and responding to external conditions and capable of controlling sensor components operation said controlling device being a pressure or proximity detector configured to enable sensor operation only when the performing component is fastened to the tissue to the extent that the detector only receives rays which are reflected from the tissue.
