Ubiquitous Energy being absorbed. Developed from research done at Massachusetts Institute of Technology (MIT) they have developed organic photoactive materials (organic photovoltaics, OPVs) that allow visible light to pass through its technology but selectively absorb the light from the invisible part of the spectrum, near infrared (NIR) and ultraviolet (UV) light. They call this technology ClearView power. ClearView Power is an invisible film less than 1/1000 of a millimeter thick that can be put onto any surface and generate energy without with out affecting the material beneath it. Specifically they are trying to capture all of the photons of ultraviolet and infrared
Invisible ink purpose stylus, stamp, fountain pen, toothpick, calligraphy pen, or even a finger dipped in the liquid. Once dry, the written surface looks as if it were blank, with a similar texture and reflectivity as the surrounding surface. The ink can be later made visible by different methods according to the type of invisible ink used. The ink may be revealed by heat or by application of an appropriate chemical, or it may be made visible by viewing under ultraviolet light. Inks which are developed by a chemical reaction may depend on an acid-base reaction (like litmus paper), reactions similar to
