“…[25][26][27] To combine the advantage of both SCs and LIBs, aqueous lithiumion capacitors (ALICs) show the promising potential for the wearable energy storage. [28][29][30][31][32][33][34] Compared to the significant achievement of cathodes, the lack of high-capacitance fibrous anodes is the major limitation in the development of the high-performance fiber-shaped aqueous LICs (FALICs).

Fiber‐shaped aqueous lithium‐ion capacitors (FALICs) featured with high energy and power densities together with outstanding safety characteristics are emerging as promising electrochemical energy‐storage devices for future portable and wearable electronics. However, the lack of high‐capacitance fibrous anodes is a major bottleneck to achieve high performance FALICs. Here, hierarchical MoS2@α‐Fe2O3 core–shell heterostructures consisting of spindle‐shaped α‐Fe2O3 cores and MoS2 nanosheet shells on a carbon nanotube fiber (CNTF) are successfully fabricated. Originating from the unique core/shell architecture and prominent synergetic effects for multi‐components, the resulting MoS2@α‐Fe2O3/CNTF anode delivers a remarkable specific capacitance of 2077.5 mF cm−2 (554.0 F cm−3) at 2 mA cm−2, substantially outperforming most of the previously reported fibrous anode materials. Further density functional theory calculations reveal that the MoS2@α‐Fe2O3 nano‐heterostructure possesses better electrical conductivity and stronger adsorption energy of Li+ than those of the individual MoS2 and α‐Fe2O3. By paring with the self‐standing LiCoO2/CNTF battery‐type cathode, a prototype quasi‐solid‐state FALIC with a maximum operating voltage of 2.0 V is constructed, achieving impressive specific capacitance (253.1 mF cm−2) and admirable energy density (39.6 mWh cm−3). Additionally, the newly developed FALICs can be woven into the flexible textile to power wearable electronics. This work presents a novel effective strategy to design high‐performance anode materials for next‐generation wearable ALICs.

Wearable sensing systems, as a spearhead of artificial intelligence, are playing increasingly important roles in many fields especially health monitoring. In order to achieve a better wearable experience, rationally integrating the two key components of sensing systems, that is, power supplies and sensors, has become a desperate requirement. However, limited by device designs and fabrication technologies, the current integrated sensing systems still face many great challenges, such as safety, miniaturization, mechanical stability, energy‐efficiency, sustainability, and comfortability. In this review, the key challenges and opportunities in the current development of integrated wearable sensing systems are summarized. By summarizing the typical configurations of diverse wearable power supplies, and recent advances concerning the integrated sensing systems driven by such power supplies, the representative integrated designs, and micro/nanofabrication technologies are highlighted. Lastly, some new directions and potential solutions aiming at the device‐level integration designs are outlooked.

“…[10][11][12][13][14][15][16] Different wearable devices have recently adapted this strategy to collect energy from human or the environment followed by regulating and storing the scavenged energy in storage modules such as batteries or supercapacitors (SCs). [17][18][19][20][21][22][23] However, the operation of these systems has relied on either a monolithic input source which shares the same limitation in energy availability (e.g. the lack of motion, biofuel, sunlight), or upon multiple harvesters that operate in parallel but are not synergistic in realistic scenarios, and introduce additional limitations instead of compensating existing ones.…”

Despite the fast development of various energy harvesting and storage devices, their judicious integration into efficient, autonomous, and sustainable wearable systems has not been widely explored. Here, we introduce the concept and design principles of e-textile microgrids to the world of wearable electronics by demonstrating the operation of a multi-module bioenergy microgrid system. Unlike earlier hybrid wearable energy systems, the presented e-textile microgrid relies solely on human movements to work synergistically, harvesting biochemical and biomechanical energy using sweat-based biofuel cells and triboelectric generators, and regulating the harvested energy via supercapacitor modules for high-power output. Through careful energy budgeting, the versatile e-textile system offers fast-booting and extended-harvesting to efficiently power liquid crystal displays continuously or a sweat sensor-electrochromic display system in pulsed sessions. Implementing the “compatible form factors, commensurate performance and complementary functionality” design principles, the flexible, textile-based bioenergy microgrid offers attractive prospects for the design and operation of efficient, sustainable, and autonomous wearable systems.
