“…[1] At present, conventional desalination technologies such as reserve osmosis, electrodialysis, and membrane distillation are complex and inefficient. [2,3] Solar-driven steam generation (SSG) process can efficiently convert clean and free solar energy into heat for sustainable desalination and purification. [4,5] Energy conversion efficiency can be improved through material innovation, fabrication method optimization, structural design with different dimensions, and synergy of multiple energy sources.…”

The shortage of fossil fuels and freshwater resources has become a serious global issue. Using solar energy to extract clean water with a photothermal conversion technology is a green and sustainable desalination method. Integrated electricity generation during the desalination process maximizes energy utilization efficiency. Herein, a solar‐driven steam and electricity generation (SSEG) system based on an all‐in‐one evaporator is prepared via a scalable technology. Carbon black is selected as the absorber for solar energy harvesting as well as the functional substance for simultaneous electricity generation. Fabric substrate with flexible structure, porous channel, and capillary effect is vital for directional brine supply, multiple solar absorption, and thermal management. The high evaporation rate (1.87 kg m−2 h−1) and voltage output (324 mV) can be achieved with an all‐in‐one device. The stable electricity output can be maintained over 40000 s. The SSEG performance remains constant after 15 operation cycles or 20 wash cycles. The integrated device balances excellent effectiveness and practicality, providing a viable path for clean desalination and electricity generation.

“…These hydrogels can be typically fabricated by direct addition of the conductive materials into the precursor solution for hydrogel formation, or post‐modification of the pre‐formed hydrogels with conductive materials 26 . Particularly, creation of porous structures in the hydrogels can increase the deformation of their polymeric networks under centain stretching, thereby improving their sensitivity 27–31 . Such porous structures are usually created by using pore‐forming templates such as alginate‐particle suspensions, 32 sodium chloride particle, 33 and high internal phase emulsion 34 .…”

A stretchable conductive Janus hydrogel with controllable porous structures is developed for highly sensitive monitoring of human motion. The Janus porous structure of the hydrogel is fabricated using patterned single‐layer droplets produced by microfluidics as pore‐forming templates. The hydrogel possess dual‐crosslinked polymeric networks to achieve good stretchability (480%), which allows fully cover the stretching range of human skin (usually <200%). Meanwhile, the hydrogel possess controllable Janus porous structures with local strain/stress enhancement to achieve high sensitivity (GF = 5.2) for strain‐sensing. The Janus hydrogel shows fast response for stretching (175 ms) and recovery (170 ms), and good durability (200 cycles at 50% strain). The conductive Janus hydrogel with high sensitivity and good mechanical properties are promising for developing soft wearable sensors in fields such as human health monitoring and human motion detection.
