Patent Title: A Cavity Based Multi-Resonant Piezoelectric Energy Harvester with One Straight and Two L-Shaped Branches

Granting ID: 202111032091

Specification: This patented invention introduces an innovative multi-resonant piezoelectric energy harvester that combines a straight cantilever beam with two L-shaped beams, each featuring strategically placed cavities. The design delivers three fundamental resonance peaks within a frequency range of less than 10 Hz under a low input base acceleration of 0.2 g. This structure significantly enhances output voltage and power generation at low frequencies while addressing narrow bandwidth limitations of conventional harvesters. The optimized geometry—with cavities located at critical points—improves performance metrics: for example, under 0.2 g excitation and optimal load (≈100 kΩ), the device achieves output voltages of 50.4 V, 23 V, and 30.7 V, and power outputs of 12,600 µW, 2,640 µW, and 4,720 µW across the three resonant modes
