Abstract: An energy harvesting brake system may comprise a shaft, a roller cylinder, and a piezoelectric material. The roller cylinder may be configured to rotate relative to the shaft in response to a target moving relative to a platform. The piezoelectric material may be in operable communication with the shaft and the roller cylinder such that relative rotational motion between the shaft and the roller cylinder causes cyclic stress in the piezoelectric material thereby generating electrical energy.
