Abstract
A nonlinear magnetic force-based arched piezoelectric ceramic energy harvesting deceleration strip, which comprises an outer case and an internal generating mechanism. The outer case structure comprises an upper deceleration strip and a casing. The casing is embedded in the pavement structure by excavating the upper part of surface course. A rebounding mechanism is located between the upper deceleration strip and casing to restore the pressed upper deceleration strip. Features: the generating mechanism comprises a rack, a gear set and generating discs. The rack is disposed at the bottom of the upper deceleration strip and moving up and down therewith. The rack can drive the gear set to generate acceleration, and the transmission shafts drive the left and right generating discs to rotate. The gear set is combined with three transmission shafts.
