From Fig. 1, it can be seen that the energy acquisition converter consists of a piezoelectric, photoelectric transducer, interface circuit, power conversion module, acquisition module, and drive module. Composed of dynamic module and management control module. Optoelectronic, piezoelectric transducers, and interface circuits form the input terminal, which converts vibration energy and light In today's research landscape focused on efficient energy utilization [2, 3], nanogenerators (NGs) and supercapacitors play pivotal roles in harvesting energy from microenergy sources [4, 5].However, the unpredictability of these sources challenges device reliability, prompting exploration into hybrid solutions that can harness energy from multiple sources simultaneously or intermittently. A hybrid energy harvesting scheme and system integrating radio frequency (RF) electromagnetic wave and solar energy based on optically transparent metasurface is proposed and constructed for the first time in this article. The scheme combines the RF link and the solar link through the high-efficiency transparent metasurface and rectifier circuit, the solar cell, and the power management
