Abstract:

The objective of this study was to design, develop and test a multimechanism energy harvesting device to harvest energy from mechanical vibrations using two different mechanisms viz. Piezoelectric Effect and Faraday�??s Law of Induction. In this study, we have demonstrated multimodal energy harvesting using piezoelectric and electromagnetic materials, utilizing mechanical vibrations as primary source of energy. Multimodal Energy Harvesting captures energy from two or more sources or mechanisms using �??Product Effect�?�. Development of new piezoelectric compositions for enhancing the energy density using conventional ceramic processing route was followed by design and development of electromagnetic energy harvester. Fabrication of multimechanism device involved a magnetic levitation harvester with piezoelectric bimorph sandwiched between the two permanent magnets moving inside a coil. Multimodal energy harvesting enhances output energy of a harvester and can be utilized for many on-board sensor applications such as harvested energy from a car�??s engine vibrations can be used to supply additional energy to the wireless sensors on board, such as temperature sensor and dashboard indicators, whose power requirements are of the order of several milliwatts (mW).
