Abstract In the rapidly advancing semiconductor sector, thermal management of chips remains a pivotal concern. Inherent heat generation during their operation can lead to range issues such as potential runaway, diminished lifespan, and current leakage. To mitigate these challenges, study introduces superhygroscopic hydrogel embedded with metal ions. Capitalizing on intrinsic coordination chemistry, metallic ions in form robust structures non‐metallic nitrogen oxygen through empty electron orbitals lone pairs. This unique structure serves an active site for water adsorption, beginning primary layer chemisorbed molecules subsequently facilitating multi‐layer physisorption via Van der Waals forces. Remarkably, cobalt‐integrated demonstrates capability harvest over 1 5 g −1 atmospheric at 60% RH 95% RH, respectively. Furthermore, efficiently releases entirety its absorbed modest 40°C, enabling recyclability. Owing significant absorption capacity minimal dehydration temperature, reduce chip temperatures by 5°C process, offering sustainable solution electronics.

Atmospheric water harvesting has emerged as an efficient strategy for addressing the global challenge of freshwater scarcity. However, in being energy-consuming water-collecting process obstructed its practicality. In this work, a soft drain bed, which was composed hydrophilic cloth and hygroscopic gel, been demonstrated to capture atmospheric effectively, followed by converting it into liquid spontaneously sustainably, under all-weather humidity conditions. Under optimal working condition 30°C with relative level 75%, bed can provide spontaneous oozing ability 1.25 g (liquid water)/hour within 8 h time. More importantly, after 5 cycles, 80% be reserved, suggesting high potential practical supply application. The proposed design is expected new hints development future energy-saving decentralized systems.
