🌍 Introduction to Hybrid Energy Harvesting
Continuous monitoring of power transmission lines is vital for ensuring grid reliability, fault detection, and preventive maintenance ⚙️. However, supplying uninterrupted power to monitoring sensors installed on high-voltage lines remains a major challenge. Hybrid Piezoelectric and Photovoltaic Energy Harvesters offer a smart, self-sustaining solution by converting ambient mechanical and solar energy into usable electrical power 🌞⚡. ⚙️ Concept of Hybrid Energy Harvester 🔹 Piezoelectric Energy Harvesting Piezoelectric materials generate electrical energy when subjected to mechanical stress or vibrations. In power lines, wind-induced oscillations, conductor galloping, and electromagnetic vibrations create an ideal environment for piezoelectric transducers 🎯. These devices efficiently convert dynamic motion into electrical signals, especially during low-light or nighttime conditions 🌙. 🔹 Photovoltaic Energy Harvesting Photovoltaic (PV) cells capture solar radiation and transform it ...
