“…[106] An example is a UV patch fabricated on a patterned PI substrate and consisting of polyaniline in its emeraldine base form (PANI-EB) as the conducting medium, triphenylsulfonium triflate (TST) as the photoacid generator (PAG), and polyethylene glycol (PEG) as the proton conductor (Figure 5a). [41] Upon www.advmattechnol.de UV illumination, the H + released by TST converted the PANI-EB to a conductive PANI-salt. This resulted in a change in the resistance, which had the potential to be exploited to detect UV radiation.…”

The tremendous impact of UV radiation on every individual has resulted in massive interest in development of new sensor technologies to effectively monitor the solar exposure. However, there is no comprehensive review that critically discusses the advances made in the field of wearable UV sensor technologies and to position them as next‐generation mass‐deployable wearable devices. Herein, this gap is addressed by first classifying UV detection technologies into photoelectric and photochromic systems and summarizing their unique strengths and drawbacks. This is followed by a discussion on the integration of novel materials and design concepts with these technologies to develop wearable UV sensors. Then, the commercially available wearable UV sensors are examined thoroughly together with their limitations. Toward the end, a highly critical future outlook is provided, wherein the role of technological and regulatory interventions in assisting the development and integration of wearable UV sensors in the day‐to‐day activities is discussed. More importantly, the purpose of this review is not only to provide an in‐depth understanding of the underlying UV detection mechanism, design principles, and wearable technologies but also to act as a roadmap for those interested in the development and regulation of commercially deployable wearable UV sensors.

“…Smart textiles help the user to sense and respond to external stimuli, and ideally adapt to them. 1 The need for UV-sensors to detect UV rays from sunlight is demonstrated using a variety of materials like hydrated tungsten oxide nanosheets, 2 conductive polymer and CNT composites, 3 uorescent polyoxometalate and viologen, 4 multifunctional ZnO-based biolms 5 and various photochromic compounds 6 in recent research studies. For smart textile applications, photochromic materials provide excellent properties to function as exible sensors, which display a reversible colour change and therewith warn the user of the presence of harmful UV-radiation in everyday situations where UV-light is not an obvious threat, i.e.…”

Health concerns as a result of harmful UV-rays drive the development of UV-sensors of different kinds. In this research, a UV-responsive smart textile is produced by inkjet printing and UV-LED curing of a specifically designed photochromic ink on PET fabric. This paper focuses on tuning and characterizing the colour performance of a photochromic dye embedded in a UV-curable ink resin. The influence of industrial fabrication parameters on the crosslinking density of the UV-resin and hence on the colour kinetics is investigated. A lower crosslinking density of the UV-resin increases the kinetic switching speed of the photochromic dye molecules upon isomerization. By introducing an extended kinetic model, which defines rate constants k colouration , k decay and k decolouration , the colour performance of photochromic textiles can be predicted. Fabrication parameters present a flexible and fast alternative to polymer conjugation to control kinetics of photochromic dyes in a resin. In particular, industrial fabrication parameters during printing and curing of the photochromic ink are used to set the colour yield, colouration/decolouration rates and the durability, which are important characteristics towards the development of a UV-sensor for smart textile applications.
