Scientists have developed a groundbreaking transparent device capable of harvesting both radio waves and sunlight simultaneously to generate power. This innovation has the potential to revolutionize wireless device energy autonomy, significantly enhancing energy efficiency and sustainability.
A Breakthrough in Energy Harvesting
Traditional energy collection systems typically rely on a single source, either solar power or radio frequencies. However, the newly developed optically transparent rectenna metasurface system (RMS) captures both Wi-Fi signals (2.4 GHz and 5.8 GHz) and sunlight, ensuring a continuous and sustainable energy supply.
Why This Technology Matters
Dual-Source Energy Collection: Simultaneously harnesses solar and radio wave energy for uninterrupted power.
80% Optical Transparency: Can be integrated into various surfaces without affecting aesthetics.
Versatile Applications: Suitable for smart windows, energy-generating building facades, self-charging screens, and vehicle components.
Efficient Power Conversion: Achieves RF-to-DC conversion efficiencies of 19.64% at 2.4 GHz and 7.92% at 5.8 GHz.
Enhanced Solar Integration: Boosts solar panel output by 13.11%, improving overall energy efficiency.
A Step Toward a Sustainable Future
From smart cities to portable electronics, this breakthrough technology could reshape how we meet our energy needs in the future, paving the way for a more self-sufficient and eco-friendly world.
