A Novel Magnetic-Coupling Non-Contact Piezoelectric Wind Energy Harvester With a Compound-Embedded Structure

Weilin Liao et al.

Summary: In this study, a magnetic-coupling non-contact piezoelectric wind energy harvester with a compound-embedded structure is proposed to enhance power generation performance, environmental adaptability, and reliability. By altering the interference effect of a square plate on a cylinder, the performance improvement and suppression of power generation are achieved. Through simulations and experiments, the feasibility and effectiveness of the proposed harvester are validated.

Enhanced piezoelectric wind-induced vibration energy harvester via the interplay between cylindrical shell and diamond-shaped baffle

Junwu Kan et al.

Summary: This paper presents an enhanced piezoelectric wind-induced vibration energy harvester (EPWEH) that improves reliability, environmental adaptability, and power generation performance by introducing a downstream diamond-shaped baffle to change the aeroelastic instability of the cylindrical shell. Experimental results demonstrate that the compound-embedded structure significantly enhances the power generation performance of EPWEH, achieving a high voltage output enhancement and maximum output power density.

Exploring 1:3 internal resonance for broadband piezoelectric energy harvesting

M. Aravindan et al.

Summary: Recent literature suggests that spectral characteristics of a harvester can be enhanced by invoking internal resonance between modes. This study analyzes the nonlinear dynamics and harvesting performance of a 1:3 internally resonant piezoelectric cantilever beam with a lumped mass under harmonic excitation. The results show that the higher mode invoked through internal resonance plays a significant role in broadband power generation.
