Numerical-experimental study of a multi-branch l-shaped broadband piezoelectric energy harvester based on modal densification
Piezoelectric energy harvesting (PEH) offers a sustainable power solution for low-power electronic devices, such as internet of things nodes, wireless sensor networks, and micro-electromechanical systems, by converting ambient mechanical vibrations into electrical energy. Among various multimodal PEH designs, the L-sha...

Bandwidth-Enhanced Low-Frequency Piezoelectric Energy Harvesting via Multimodal Response of a Planar Fermat Spiral Harvester
Enhancing the bandwidth of low-frequency vibration energy harvesting remains challenging for conventional piezoelectric cantilever harvesters because their effective response is usually confined to a narrow resonance band. This study proposes a compact Fermat spiral piezoelectric energy harvester that exploits geometry...

An Explainable Physics-Informed Neural Frequency-Response Framework for Shunt-Parameter Identification in Semi-Active Piezoelectric Tuned Mass Dampers
This paper proposes a Physics-Informed Neural Frequency Response Framework for learning and interpreting the frequency-domain behavior of semi-active shunted piezoelectric tuned mass dampers. The motivation is that the behavior of such systems is most naturally expressed through frequency response functions, while the...

Theoretical, numerical, and experimental analysis of a broadband and high-capability graded E-shaped piezoelectric energy harvester array under various vibrations
Harvesting energy from the environment to energize IoT nodes is a contemporary study focal point. Contemporary research fails to achieve wideband and high-efficiency energy harvesting concurrently, and the majority of studies neglect the stochastic characteristics of ambient vibrations, hence hindering the practical ap...

Energetic frontier theory for smart piezoelectric structures with coupled vibration attenuation and energy harvesting
Piezoelectric energy harvesters and shunted smart structures are often analyzed separately as power generators and vibration absorbers, even though both functions arise from the same electromechanical coupling. This paper asks a joint design question: for a prescribed residual-vibration level, what is the largest usefu...
