devices) of electronics miniature, thin, lightweight, flexible, foldable, stretchable, self-healable, implantable, or wearable. [2][3][4] One of the key challenges for wearable electronics is to find suitable and sustainable power sources. Electrochemical energy-storage devices, especially rechargeable lithium-ion batteries (LIBs), have been widely applied and successfully promoted the thriving growth of portable electronics for decades. However, stateof-the-art batteries' technology is, increasingly, becoming a bottleneck for the rapid advancements of wearable electronics for the following reasons: first, the high power consumption of multifunctional electronics requires energy-storage devices with higher energy in smaller volume or lighter weight so that longer operational time or less frequent recharging can be achieved for the convenience of consumers; second, batteries or supercapacitors typically feature a configuration of stacked planar porous electrodes with inorganic oxide-, phosphate-, or hydroxidebased active materials, which make them hard to be flexible or stretchable. [5,6] Tremendous efforts have been dedicated to improve the energy density of batteries or supercapacitors, [7,8] or developing flexible/wearable batteries/supercapacitors. [9] These progresses have been summarized in other reviews and will not be included here. [10][11][12] Despite these advancements, the battery or supercapacitor, still, can hardly meet the above requirements of wearable electronics. [13] Therefore, extensive research interest recently turns to the assistance of energyharvesting or conversion devices, in a way that energy-storage and -harvesting technologies are combined into self-charging power systems (SCPSs) for wearable electronics, as schematically illustrated in Figure 1. [14][15][16] Energy-storage and -harvesting technologies have always been two blades of a sword. Renewable energy resources (e.g., solar, wind, vibration, or biomass) are highly dependent on when and where they are available, which makes energy-storage devices (e.g., battery, capacitors, pump hydro, or compressed air) indispensable for stable or smart power supply. Portable/ wearable energy-storage devices possess limited energy, making it an effective strategy to utilize wearable energy-harvesting devices to compensate the energy consumption of the batteries/ supercapacitors, so as to elongate the operational time, reduce the recharging frequency, or even form a self-sufficient power system for the electronics. Various technologies have been developed to convert the environmental energies into electricity, One major challenge for wearable electronics is that the state-of-the-art batteries are inadequate to provide sufficient energy for long-term operations, leading to inconvenient battery replacement or frequent recharging. Other than the pursuit of high energy density of secondary batteries, an alternative approach recently drawing intensive attention from the research community, is to integrate energy-generation and energy-storage devices ...
