Abstract The small‐scale‐dependent nonlinear dynamical attributes of microplate‐type laminated piezoelectric systems harvesting energy subjected to a triangular mechanical actuation are explored in the current exploration. core is supposed be made nanocomposites reinforced by randomly oriented carbon nanotubes (CNTs) having various degrees agglomeration coated layers. In this regard, modeled via quasi‐3D plate theory combined with modified strain gradient elasticity presence microsize‐dependent tensors. Thereafter, solution developed coupled electromechanical size‐dependent problem obtained numerically utilizing meshless collocation approach employing incorporation polynomial and radial basis functions remove any feasible singularity for associated moment matrices. It comes conclusion that elevating quantity CNTs disclosed within clusters, significance microsize dependency achieved voltage enhances from 22.06% 22.73% toward simply supported bridge‐type context, 33.00% 33.92% clamped context. Highlights Development microstructural‐dependent shear flexible harvester model. Incorporating roles tensors dynamics microharvesters. Size‐dependent time‐histories mechanical‐loaded Influence CNT reinforcement clustering on dynamic performance.

A Multi‐Degree‐of‐Freedom Piezoelectric Kinetic Energy Harvester for Self‐Powered Wireless Sensors in Electric Buses

Energy Technology, Journal Year: 2025, Volume and Issue: unknown

Published: March 21, 2025

Harvesting energy from the surrounding environment represents a viable method for developing self‐powered systems and realizing that vehicles' low‐power sensors are self‐powered. Nevertheless, existing harvesting devices exhibit limitations in their capacity to capture kinetic across broad spectrum of motion. To overcome this limitation, multi‐degree‐of‐freedom piezoelectric harvester has been developed, comprising three modules: motion conversion, transformation, power storage. The conversion module utilizes connecting rod sliding bearing mechanism transform complex three‐dimensional motions swing body into simplified two‐dimensional movements mass. transformation elements convert mechanical electrical energy, which is then rectified stored capacitors by storage module. Experimental results demonstrate system's capability generate maximum average output 758 μW. Capacitor charging tests show 100, 330, 470 μF can be charged 1 V 20, 32, 50 s, respectively. Real‐world vehicle confirm practical applicability harvester, providing valuable insights wireless sensor systems.
