This study presents a groundbreaking strategy in wearable electronics by combining wearable antennas with perovskite solar cells, enabling sophisticated communication capabilities while utilizing sustainable energy sources. The flexible and lightweight perovskite solar cells offer a viable alternative for sustainable power generation in wearable devices. The design process aims to create a synergistic architecture that avoids mutual interference between the antenna and solar cell. Perovskite solar cells transform solar energy into electrical power, which powers the wearable antenna and other low-power devices. Stable power supply is produced through efficient power management circuits, while performance optimization increases the gain and efficiency of the antenna and solar cell. The integrated device is made to last and be reliable, with potential applications in fitness tracking, smart textiles, and vital sign data transmission.
