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 (IoT) devices to portable power generator to distributed power sources. The presentation will emphasize advances made in synthesis of novel material architectures such as textured piezoelectrics, mixed organo-halide perovskites, segmented 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 multifunctional materials synthesized in thick film / bulk form have provided the opportunity to develop devices with specific figure of merit resulting in high efficiency and power density. In-depth discussion of the design, modeling and testing procedures for energy harvesters will be provided to promote the consistency in reporting. Throughout the presentation, examples of applications and prototype devices will be provided to illustrate the relevance of energy harvesting.
