Distributed parameter modeling for autonomous charge extraction of various multilevel segmented piezoelectric energy harvesters

Design and simulation of cavity and piezoelectric material structure in segmented doubly clamped piezoelectric energy harvester

“…20 Where, the performance of segmented DCPEH is found to be in good agreement with the experimental results. [21][22][23] In this paper, the experimentally verified segmented DCPEH beam has been considered as a basic device in which the effects of cavity inclusion and use of multilayer piezoelectric composites have been analyzed through analytical and simulation study.…”

Correlating multimode strain and electrode configurations for high-performance gradient-index phononic crystal-based piezoelectric energy harvesting

“…Based on multimodal strain analysis, various EH device designs such as segmented piezoelectric ceramics and patterned electrode configurations, whereby the strain node is not located within the same active piezoelectric layer, have been proposed. 24–26…”

“…Based on multimodal strain analysis, various EH device designs such as segmented piezoelectric ceramics and patterned electrode configurations, whereby the strain node is not located within the same active piezoelectric layer, have been proposed. [24][25][26] Beyond conventional energy harvesting research efforts on materials, devices, and circuits, a further disruptive approach for power enhancement in energy harvesting is required. Phononic crystals (PnCs) and acoustic metamaterials (AMMs) are artificially engineered structures with a remarkable wave manipulation capability owing to their unconventional properties, such as bandgap, negative bulk modulus, negative mass density, and negative refractive index.…”
