Abstract
The invention discloses a flexible, energy-self-sufficient UV dosimeter which optically indicates the absorbed dose on the basis of the intensity and duration of the irradiation via a color change. The invention contains one or more UV dosimeter modules. Exemplary UV dosimeter modules include at least one UV-sensitive photodiode (common electrode (), hole conductor layer (), UV absorber layer (), cathode ()) and an electrochromic element (common electrode (), ion storage layer (), electrolyte layer (), electrochromic layer made of redox active material (), transparent electrode ()), between which an insulator () and a conductor track () are arranged. The electrochromic element accumulates the charge generated by the UV-sensitive photodiode and indicates this by means of a color change. The UV dosimeter can be produced as an integrated circuit using thin-film technology by successively applying and structuring organic or inorganic functional layers.
