Ionic Hydrogels Based Wearable Sensors to Monitor the Solar Radiation Dose for Vitamin D Production and Sunburn Prevention

Abstract: Wearable solar radiation sensors based on ionic hydrogels are facilely prepared to simultaneously monitor the radiation dose for the production of vitamin D and the prevention of sunburn. Tetramethylethylenediamine (TEMED) is neutralized with acrylic acid (AA) to obtain tetramethylethylenediamine acrylate (TEMEDA), which is further polymerized with acrylamide by a free radical reaction. By simply adding MB or NR during the polymerization, the final obtained ionic hydrogels can indicate solar radiation. Due to … Show more

“…17 OEGMA 300 -co-EGMA) hydrogel coating was cross-linked on a PU band. 23 Due to the switching capability between hydrophobic and hydrophilic state of the coating surface, stains can be easily removed from the PU band by simply rinsing it with water. Therefore, the cross-linked hydrogel coating presents a promising approach to enhance the cleaning performance of PU.…”

“…In addition, their transition temperature (TT) is correlated to the number of ethoxy groups in the side chains of the monomers. Hence, the TT of acrylate-based thermoresponsive polymers can be easily tuned by selecting the monomers and adjusting the molar ratio. In our previous investigation, a hybrid alginate-Ca 2+ /P­(MEO 2 MA- co -OEGMA 300 - co -EGMA) hydrogel coating was cross-linked on a PU band . Due to the switching capability between hydrophobic and hydrophilic state of the coating surface, stains can be easily removed from the PU band by simply rinsing it with water.…”
