Phosphorescence from organic compounds has typically been observed at extremely low temperatures and in the absence of oxygen, which limits their scope for practical applications.

Heat and light, being modes of motion, «
phosphorescence» and «incandescence» are phenomena to which consciousness has been likened by the production - theory: «As one sees a metallic rod, placed in a glowing furnace, gradually heat itself, and — as the undulations of the caloric grow more and more frequent — pass successively
from the shades of bright red to dark red (sic), to white, and develope, as its temperature rises, heat and light, — so the living sensitive cells, in presence of the incitations that solicit them, exalt themselves progressively as to their most interior sensibility, enter into a phase of erethism, and at a certain number of vibrations, set free (dégagent) pain as a physiological expression of this same sensibility superheated to a red - white.»
Now, the «smart» bandage developed by the team provides direct, noninvasive measurement of tissue oxygenation by combining three simple, compact and inexpensive components: a bright sensor molecule with a long
phosphorescence lifetime and appropriate dynamic range; a bandage material compatible with the sensor molecule that conforms to the skin's surface to form an airtight seal; and an imaging device capable of capturing the oxygen - dependent signals
from the bandage with high signal - to - noise ratio.
