Zinc-ion microcapacitors (ZIMCs) have gained considerable attention for their intrinsic charge storage mechanisms, combining a battery-type anode with capacitor-type cathode. However, development is constrained by challenges related to electrode material selection and microscale device design, especially given the limited footprint of such devices. Despite potential, exploration smart processing hybrid materials on-chip ZIMCs remains limited. In this work, we introduce 3D gold interdigitated electrodes (3D Au IDEs) as highly porous current collectors, loaded zinc (Zn) activated carbon coated PEDOT (AC-PEDOT) cathode, using an advanced microplotter fabrication technique. Compared planar Zn//AC ZIMCs, where Zn AC are onto IDEs, Zn//AC-PEDOT demonstrate significantly enhanced performance. This attributed critical role IDEs in increasing capacity, improving long-term cycling stability, boosting capacitive-controlled contributions. The achieve areal capacity 1.3 μAh/cm2, peak energy 1.11 μWh/cm2, power 640 μW/cm2, surpassing most reported microsupercapacitors. study highlights how optimized collectors enhance microdevice while maximizing performance within footprint.
