Self-Hygroscopic Hydrogels In their Research Article (10.1002/adsu.202501720), Chirodeep Bakli and co-workers utilize a self-sustaining hydrogel with wind-enhanced evaporative cooling for electronics cooling and simultaneous waste heat recovery. The hygroscopic material helps capture ambient moisture, maintaining efficient thermal regulation without external water input. Integrated thermoelectric modules simultaneously convert dissipated waste heat into electricity, offering a scalable, low-energy solution for sustainable thermal management and power recovery.
