Furthermore, such a hydrogel layer chemically bonded on the Zn surface possesses an anti-catalysis effect, which effectively suppresses both the hydrogen evolution reaction and formation of Zn dendrites. As a result, stable and reversible Zn stripping/plating at various currents and capacities is achieved. A full cell by pairing the Zn-SHn anode with a NaV 3 O 8 •1.5 H 2 O cathode shows a capacity of around 176 mAh g −1 with a retention around 67% over 4000 cycles at 10 A g −1 . This polyanionic hydrogel film protection strategy paves a new way for future Zn-anode design and safe aqueous batteries construction.

Along with the rapid growth in electronics technology, electrical power solutions are developed to provide high‐performance, reliable, and durable energy supplies to various electronic devices. However, conventional power systems are challenging owing to serious after‐use considerations, including environmental costs and biological hazards of eliminating heavy metals and other toxins. Here, this Perspective provides a comprehensive review of recent progress in techniques associated with transient, biodegradable, environment‐friendly energy solutions, including batteries, supercapacitors, energy harvesters utilizing various types of energy sources (e.g., biochemical, physical/mechanical, or thermal), and external energy transfer strategies (e.g., inductive coupling/radiofrequency, photovoltaic, or ultrasonic). Key features, practical examples, existing challenges, and finally possible future directions for transient, biodegradable energy solutions with unmet approaches yet are presented.

Solar cells offer an environmentally sustainable and convenient option for power source of next‐generation wearable electronics. Due to the advantages of low cost, easy fabrication and deformation, fiber dye‐sensitized solar cells (FDSSCs) are required to be suitable for the available wearable electronics. Herein, through introduced nanopillar arrays over the Ti wire and atomic layer deposition of conformal TiO2 layer to make the photoanode, the energy conversion efficiency of the FDSSCs is improved by 45%. The FDSSCs are combined with planar microsupercapacitor (MSC) clusters to make self‐charging power system on a polymer sheet. The interdigital finger electrodes of MSC were obtained in a single‐step method by laser‐inducing on a polyimide film, and two series can be charged up to 1.8 V in 30 s by the FDSSCs under solar irradiation. This power sheet can be attached to various surfaces such as skin, cloths, and electronic devices for practical applications.
