Abstract: The invention relates to an electric surface heater, or heating mat, based on an electrically conductive polymer foil or a conductive polymer foam that only heats locally where persons, animals or objects are positioned on the mat. Energy can thereby be saved in comparison with a full-area heater. Ideally, this local heat generation functions without any external electronic control or regulation.

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 (11), hole conductor layer (21), UV absorber layer (22), cathode (23)) and an electrochromic element (common electrode (11), ion storage layer (12), electrolyte layer (13), electrochromic layer made of redox active material (14), transparent electrode (15)), between which an insulator (4) and a conductor track (5) 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.

Abstract: The invention describes electrically conductive shaped bodies with an inherent positive temperature coefficient (PTC), produced from a composition which contains at least one organic matrix polymer (compound component A), at least one submicroscale or nanoscale, electrically conductive additive (compound component B) and at least one phase-change material with a phase-transition temperature in the range from ?42° C. to +150° C. (compound component D). The phase-change material is incorporated into an organic network (compound component C). The electrically conductive shaped body with an inherent PTC effect is, in particular, a filament, a fibre, a spun-bonded web, a foam, a film, a foil or an injection-moulded article. The switching point for the PTC behavior is dependent on the type and also the phase-conversion temperature of the phase-change material. By way of example, a self-regulating surface heater in the form of a film, foil and/or textile can be realized in this way.

Abstract: Electrochromic module including first and second substrates is provided in which the first and/or second substrate are/is electrically conductive or are/is equipped with an electrically conductive coating. A first electrochromic polymer coating is arranged on the first substrate or the conductive coating, an ion-storage or charge-compensating layer is arranged on the second substrate or the conductive coating, and a polymer gel electrolyte is disposed between the electrochromic coating and the ion-storage or charge-compensating layer. The electrochromic polymer, a polymer of tetraarylbenzidine and (hetero)aromatic diol, is colorless in one redox state and colored in at least two redox states. The ion-storage or charge-compensating layer is formed from material selected from the group comprising cerium oxide, titanium oxide, tungsten oxide, nickel oxide, molybdenum oxide, vanadium oxide and mixtures thereof or redox-active polymer.
