This study presents an ultraconformable integrated wireless charging micro-supercapacitor (IWC-MSC) skin, which can be wirelessly charged to store electricity into high-capacity micro-supercapacitors (11.39 F cm⁻³) and fits well with human skin. The IWC-MSC is fabricated by evaporating solution precursors, allowing all components (electrolyte, electrode, and substrate) to be tightly integrated into a compact, all-in-one configuration. The electrode thickness can be easily regulated between 11.7 to 112.5 μm by controlling the volume of the electrode solution precursor. The IWC-MSC is flexible, ultraconformable, and lightweight, making it suitable for use in electronic skin, microrobots, and irregular human organ sensing systems. The device demonstrates excellent electrochemical performance, including a high volumetric capacitance of 11.39 F cm⁻³, and can be wirelessly charged to store energy. The wireless charging coil is integrated with the device, enabling efficient energy transfer. The IWC-MSC also shows good stability and cycling performance, with a capacitance retention of 84.15% after 3000 cycles. The device is applied in practical scenarios, such as powering a red LED, demonstrating its potential as a self-powered energy source for wearable electronics. The study highlights the development of a new method for creating thin, conformable, and compatible skin-like power sources, which could significantly enhance the convenience of energy supply in wearable and implantable devices.This study presents an ultraconformable integrated wireless charging micro-supercapacitor (IWC-MSC) skin, which can be wirelessly charged to store electricity into high-capacity micro-supercapacitors (11.39 F cm⁻³) and fits well with human skin.
