“…101,185 Supercapacitors are currently categorized into three main techniques: electric double-layer capacitors (EDLCs), pseudocapacitors, and a hybrid of these two approaches. A typical EDLC architecture consists of a thin layer of separator sandwiched between inner electrolyte-coated carbon form electrodes (activated carbon, CNT, and graphene 184,186 ) (Figure 12a). The separator must serve as both an insulator and a conduit for electrolyte ion transfer in these devices.…”

The market for wearable electronic devices is experiencing significant growth and increasing potential for the future. Researchers worldwide are actively working to improve these devices, particularly in developing wearable electronics with balanced functionality and wearability for commercialization. Electrospinning, a technology that creates nano/microfiber-based membranes with high surface area, porosity, and favorable mechanical properties for human in vitro and in vivo applications using a broad range of materials, is proving to be a promising approach. Wearable electronic devices can use mechanical, thermal, evaporative and solar energy harvesting technologies to generate power for future energy needs, providing more options than traditional sources. This review offers a comprehensive analysis of how electrospinning technology can be used in energy-autonomous wearable wireless sensing systems. It provides an overview of the electrospinning technology, fundamental mechanisms, and applications in energy scavenging, human physiological signal sensing, energy storage, and antenna for data transmission. The review discusses combining wearable electronic technology and textile engineering to create superior wearable devices and increase future collaboration opportunities. Additionally, the challenges related to conducting appropriate testing for market-ready products using these devices are also discussed.

“…It is advisable to choose cost‐effective activation methods for synthesizing carbon from biomass. However, it is important to note that the activation process may release unwanted gases, such as SO 2 and NO 2 , and caution should be exercised to avoid increasing the overall manufacturing cost by properly addressing these emissions [11] . Another advantage is that these biowastes are naturally occurring resources that are renewable and abundant [10,12] .…”

Construction of eco-benign, cost effective, and high-performance supercapacitors with improved electrolytes and hierarchical porous electrodes is necessary for effective energy storage. In this study, a gel type organic redox electrolyte made of polyvinyl alcohol (PVA)-H 2 SO 4 and an organic redox molecule, anthraquinone (PVA-H 2 SO 4 -AQ) was prepared by simple solution casting method, and was used to construct a symmetric supercapacitor (SSC) with a date stone-derived activated carbon (DSAC) having a high BET surface area (1612 m 2 /g). The DSAC was synthesized by simple carbonization method followed by activation with potassium hydroxide. The SSC exhibit a high specific capacitance of 126.5 F/g at 0.5 A/g, as well as a high energy density of 17.5 Wh/kg at a power density of 250 W/kg with high capacitance retention (87%) after 1000 GCD cycles. The present research suggests that adding anthraquinone to a PVA-H 2 SO 4 gel electrolyte improves the performance of the fabricated device significantly as compared to using pristine PVA-H 2 SO 4 or 1 M H 2 SO 4 electrolytes. The research also presents a promising approach for the development of sustainable and eco-benign materials for energy storage applications. The use of date stone waste as a precursor material for activated carbon electrodes presents an opportunity for cost-effective and sustainable energy storage. Overall, the findings of this research have important implications for the future design and fabrication of highperformance and cost-effective supercapacitors.
