Energy harvesting (EH) is the process of extracting energy from various ambient sources of energy, such as solar, wind, vibration, and thermal energy. The captured energy is stored for various applications, including sensing, actuating, and wireless autonomous systems. In the last decade, energy harvesting has gained considerable attention as a potential alternative to batteries for powering wireless sensor networks involved in various internet of things (IoT) applications.

Dr. M. Umapathy, professor of instrumentation and control engineering at National Institute of Technology Tiruchirappalli, has designed a novel multimodal piezoelectric energy harvester consisting of a primary reversed exponentially tapered beam and six secondary branched beams. The harvester’s theoretical model was developed and derived from the Euler–Bernoulli beam theory.

In this live webinar, Dr. Umapathy will discuss the design of this novel harvester as well as the noncontact excitation technique in the harvester that extends its life. He will discuss how this harvester was simulated using the COMSOL Multiphysics® software and subsequently fabricated and evaluated experimentally in the 8–30 Hz frequency range. The presentation will also include a comparison of the theoretical model with the simulated and experimental results. The webinar will conclude with a live Q&A session.
