Pennsylvania State University
Seminar: Environmental energy harvesting: magnetic field, vibrations, heat and light
Abstract: Energy harvesting provides opportunity to develop self-powered architectures, where power for electronic devices can be generated from the energy sources present in the environment. In this presentation, examples illustrating these self-powered architectures will be provided covering solar, thermal, magnetic field, and vibration energy harvesting in applications ranging from internet of things devices to portable power generator to distributed power sources. The presentation will emphasize advances made in synthesis of textured piezoelectrics, organo-halide perovskites, thermoelectrics and magnetoelectric composites. Novel synthesis techniques such as spark plasma sintering, dry/wet aerosol deposition, laser annealing and template grain growth will be discussed. These thick film / bulk ceramic synthesis methods have provided the opportunity to develop materials with specific figure of merit. Interface design through controlled laser annealing has opened the opportunity to achieve high coupling factors responsible for impedance matching. In-depth discussion of the design, modeling and testing procedures for energy harvesters will be provided to promote the consistency in reporting.
