Paper-Based Sensor for Monitoring Sun Exposure - …

2016-5-6 · An easy to use and easy to fabrie sun exposure sensor was prepared via the inkjet printing of titanium dioxide (TiO2), polyvinylpyrrolidone (PVP), and food dye on paper. The sun exposure sensor works by employing titanium dioxide (TiO2) as a photoalyst to degrade the food dyes resulting in gradual discoloration of this film. The PVP serves as a binder to allow film formation.
