Abstract:
Piezoelectric energy harvesters (PEHs) at multi-scales have received considerable attention as an enabling technology for self-powered electronic devices. Self-powered wireless sensors for structural health monitoring, biomedical and wearable applications would be great potential applications with high market demand. A key challenge has been insufficient power and voltage generation for practical applications, which necessitates creative and disruptive materials and structure design of PEHs at various scales. Accordingly, a majority of the latest research has focused on improving the efficiency of piezoelectric power harvesting devices through various ways: i) modification of device configurations, ii) design and development of piezoelectric materials with enhanced properties, and iii) alteration of electrical circuits for power harvesting and storage. In this talk, an overview of such research activities for enhanced PEH performance will be given including analytical modeling, design, and experimental characterization of piezoelectric materials and smart structures (including mechanical metamaterials) for energy harvesting.
