Abstract
To face the challenges in preparing hydrogel fibers with complex structures and functions, this study utilized a microfluidic coaxial co-extrusion technique to successfully form functional hydrogel fibers through rapid ionic crosslinking. Functional hydrogel fibers with complex structures, including linear fibers, core-shell structure fibers, embedded helical channels, hollow tubes, and necklaces, were generated by adjusting the composition of internal and external phases. The characteristic parameters of the hydrogel fibers (inner and outer diameter, helix generation position, pitch, etc.) were achieved by adjusting the flow rate of the internal and external phases. As biocompatible materials, hydrogel fibers were endowed with electrical conductivity, temperature sensitivity, mechanical enhancement, and freeze resistance, allowing for their use as temperature sensors for human respiratory monitoring and other biomimetic application developments. The hydrogel fibers had a conductivity of up to 22.71 S/m, a response time to respiration of 37 ms, a recovery time of 1.956 s, and could improve the strength of respiration; the tensile strength at break up to 8.081 MPa, elongation at break up to 159%, and temperature coefficient of resistance (TCR) up to -13.080% °C-1 were better than the existing related research.

Abstract
Aqueous zinc-ion batteries are attracting extensive attention due to the long-term service life and credible safety as well as the superior price performance between the low cost of manufacture and high energy density. The fabrication of inexpensive, high-performance flexible solid-state zinc-ion batteries, thus, are urgently need for the blooming wearable electronics. Herein, as a proof-of-concept study of waste into wealth, cellulose flakes derived from waste pomelo peel are utilized as the substrate for electrodes and hydrogel electrolytes into a flexible rocking-chair zinc-ion battery. The unique sandwich-type structure holding the flake-like cellulose substrate and linear carbon nanotubes endows the flexible cathode and anode with fast ion and electron transportation. The obtained cellulose-based hydrogel electrolytes on account of special affinity with aqueous ZnSO4 electrolyte output an excellent ionic conductivity. The assembled flexible rocking-chair zinc-ion battery benefitting from the synergistic effect of sandwich-type electrodes and cellulose-based hydrogel electrolytes demonstrates outstanding electrochemical performance and mechanical properties. This work not only puts up an effective roadmap for flexible battery devices, but also reveals the great potential of waste biomass materials in energy storage applications.

Int J Biol Macromol 2024; 254:127852.

Abstract
Conducting polymer hydrogels are typically employed in all-gel supercapacitors; however, Poly[3,4-ethylene-dioxythiophene] (PEDOT)-based hydrogel supercapacitors still suffer from low capacitance because of the low packing density of PEDOT in the electrodes. Here, we demonstrate lignosulfonate sodium (LS) as an excellent template to synthesize various LS-PEDOT conductive nanofillers for high mass-loading LS-PEDOT/PAAM hydrogel electrodes. Then, the optimum LS-PEDOT/PAAM electrode was assembled with a redox-active LS/PAAM/Fe3+ hydrogel electrolyte to form sandwich-structured all-gel supercapacitors, which could deliver a high specific capacitance of 672.5 mF/cm2 and an energy efficiency of 60 μWh/cm2, which are three times higher than the 220 mF/cm2 and 19.5 μWh/cm2 of the device without Fe3+ at the same condition. Such a device shows excellent temperature tolerance from -30 to 100 °C. Besides, the LS-PEDOT/PAAM electrode has excellent photothermal conversion effects under simulated solar illumination. The sluggish electrochemical performance of the SC under low temperatures could be significantly boosted by ~50 % under simulated solar light. All of these findings demonstrate that the capacitance performance of the PEDOT-based hydrogel device is successfully improved not only at room temperature but also under subzero conditions.

Abstract
Electrochemical capacitors operating in an aqueous electrolyte solution have become ever-more popular in recent years, mainly because they are cheap and ecofriendly. Additionally, aqueous electrolytes have a higher ionic conductivity than organic electrolytes and ionic liquids. These materials can exist in the form of a liquid or a solid (hydrogel). The latter form is a very promising alternative to liquid electrolytes because it is solid, which prevents electrolyte leakage. In our work, hydrogel polymer electrolytes (HPEs) were obtained via photopolymerization of a mixture of acrylic oligomer Exothane 108 with methacrylic acid (MAA) in ethanol, which was later replaced by electrolytes (1 M Na2SO4). Through the conducted research, the effects of the monomers ratio and the organic solvent concentration (ethanol) on the mechanical properties (tensile test), electrolyte sorption, and ionic conductivity were examined. Finally, hydrogel polymer electrolytes with high ionic conductivity (σ = 26.5 mS∙cm-1) and sufficient mechanical stability (σmax = 0.25 MPa, εmax = 20%) were tested using an AC/AC electrochemical double layer capacitor (EDLC). The electrochemical properties of the devices were investigated via cyclic voltammetry, galvanostatic charge/discharge, and impedance spectroscopy. The obtained results show the application potential of the obtained HPE in EDLC.
