promising prospects for next-generation consumer electronics in these devices, forming a bridge between traditional capacitor and battery, demonstrating quick charging/discharging, excellent cyclic stabilities, higher power densities, environment benignancy, low maintenance cost, long lifespan, and safety. [2,3] The technological advancement in consumer electronics for smart wearables has led to the innovation of bendable displays, flexible mobile phones, fitness bands, electronic skin, and smartwatches. [4][5][6] Additionally, in remote areas having inadequate power supply and scarcity of other energy reservoirs, self-powered dynamic devices have emerged as independent and self-sustainable systems for future electronics. The sustainability of these systems without any external storage system like batteries/ fuel cells minimizes the bulkiness of the system, thereby making them flexible for a variety of applications. [7][8][9] Flexible allsolid-state self-chargeable supercapacitors are a potential candidate for the new emerging wearable energy storage devices. They are safe, thin, lightweight, extremely flexible, and inexpensive. [10,11] These supercapacitors are based on wearable electronics technology, involving no power or charging source, but they suffer from poor performance. Furthermore, in contrast to traditional supercapacitors, the allsolid-state supercapacitors eliminate the risk of electrolyte spilling as well as short-circuiting between the electrodes. [12] Recently, self-powered stretchable systems or sensing platforms have been gaining popularity. Zhang et al. [13] designed an all-in-one stretchable self-powered system using a gold (Au)based triboelectric nanogenerator and stretchable graphenebased strain sensor. The coupled design principle of electronic materials and device architecture provides a promising method to develop high-performance wearable/stretchable energy storage devices and self-powered stretchable systems for future bio-integrated electronics. Practical applications of next-generation stretchable electronics hinge on developing sustained power supplies to drive highly sensitive on-skin sensors and wireless transmission modules. In another experiment, a low-cost, scalable, and facile manufacturing approach based on laser-induced graphene foams was used to fabricate a self-powered wireless sensing platform. [14] It generated stableThe demand for flexible supercapacitor sustaining green energy can go a long way in mitigating the issue of no power source in wearable electronics. Herein, a novel strategy is used to develop a self-charging supercapacitor using lead-free perovskites as piezoelectrodes and polyvinyl alcohol-potassium hydroxide (PVA-KOH) film as ionogelled electrolyte. This approach is unique as the existing conventional self-powered devices are based only on piezoelectric electrolytes. The all-solid-state supercapacitor is asymmetric, with nickel stannate (NiSnO 3 ) acting as the positrode and ferrous stannate (FeSnO 3 ) as the negatrode. These materials are non-toxic, envi...
