Abstract: Title: System for Harvesting Electrical Energy from Ambient Acoustic and Structural Vibrations The current technology pertains to a system for harvesting electrical energy from ambient acoustic noise and structural vibrations (101). The system utilizes a hybrid transducer array (102) comprising piezoelectric and electromagnetic harvesting elements (103, 104) configured to capture energy across a broad frequency spectrum. A multimodal sensing subsystem (110) continuously acquires operating parameters including vibration intensity, acoustic amplitude, voltage, current, frequency and harvested power. An edge AI-based optimization engine (111) dynamically performs harvesting-pathway selection, adaptive impedance matching (105), converter duty-cycle adjustment and multi-source energy fusion (107) under dynamically changing environmental conditions. The harvested electrical energy is processed through signal conditioning (105), rectification, DC-to-DC conversion (106) and hybrid energy storage stages (108) comprising supercapacitors and rechargeable microbattery modules. The system further integrates predictive maintenance and IoT monitoring capabilities for system-health analysis (112), anomaly detection and maintenance alert generation, thereby enabling adaptive and autonomous low-power energy harvesting for IoT devices, smart infrastructure systems and remote monitoring applications.
