Smart hydrogel sensors with intrinsic responsiveness, such as pH, temperature, humidity, and other external stimuli, possess broad applications in innumerable fields biomedical diagnosis, environmental monitoring, wearable electronics. However, it remains a great challenge to develop structural hydrogels that simultaneously body temperature-responsive, adhesion-adaptable, transparency-tunable. Herein, an innovative skin-mountable thermo-responsive is fabricated, which endows tunable optical properties switchable adhesion at different temperatures. Interestingly, able exhibit lower critical solution temperature (LCST) adapt the human by altering acrylic acid(AAc) content network. The also displays high transparency strong low temperatures, while becomes opaque feeble Furthermore, highly sensitive sensor array structure constructed harnessing vat photopolymerization three-dimensional (3D) printing. As proof of concept, attached back hand capable detecting strain differences, integrating high-temperature monitoring alarm functions visual alteration. This work provides advanced manner fabricate structured responsive hydrogels, have potential application prospects field smart medical patches devices.

The electrocatalytic reduction of nitrate to ammonia (NH3) under mild environmental conditions is attracting increasing attention, in which efficient and inexpensive transition metal catalysts, with the advantages abundancy low cost, play a key role. However, synergistic activity selectivity promotion are still highly challenging. Herein, we developed hydrogel-assisted strategy prepare FeNi nanoparticles via situ adsorption Fe/Ni precursors on polypyrrole hydrogel. After optimization, maximum NH3 yield reached 0.166 mmol h−1 cm−2, Faradaic efficiency 88.9% 86.6%. This excellent electrochemical performance was attributed mesoporous hydrophilic structure hydrogel, facilitates homogeneous loading provides channel for both charge mass transfer during reduction, important conversion NO3− NH3. Electrochemical active surface area determination impedance spectroscopy showed that introduction hydrogel increased sites improved transfer. study an effective improving electrocatalysts by utilizing three-dimensional network electrical conductivity.

Abstract Poly(N-isopropylacrylamide)-based stimuli-responsive hydrogel actuators have made significant progress. By introducing responsive modules such as photothermal nanoparticles, the can respond to environmental changes and construct anisotropic structures, allowing quickly bend realize complex shape deformation. However, there remains a need enhance mechanical properties of these hydrogels accommodate multiple deformation actions different application scenarios, compatibility between nanoparticles improve comprehensive performance materials are still issues that be solved. In this study, we modified two-dimensional MXene nanosheets with polydopamine (PDA) obtain P-MXene, which served agent stably dispersed within system. We copolymerized thermosensitive N-isopropylacrylamide (NIPAm) 2-(dimethylamino)ethyl methacrylate (DMAEMA) in situ used direct current electric field induce concentration gradient distribution P-MXene hydrogel, resulting preparation good stretchability conductivity. The structure was characterized using scanning electron microscopy Fourier transform infrared spectra. swelling properties, conductivity were studied. actuation behavior P(NIPAm-DMAEMA)/P-MXene under thickness intensity investigated. Additionally, sensitivity stability conductive tested functions monitoring human health information transmission realized. It integrated rapid photo responsiveness self-sensing capabilities monitor process through real-time relative resistance during actuations. This work is expected expand soft provide new insights into design generation robots.
