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.

An energy harvesting brake system, comprising:
- a shaft;
- a roller cylinder configured to rotate relative to the shaft in response to a target moving relative to a platform, the energy harvesting brake system being disposed in the platform;
- and
- a piezoelectric material 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.
A method of harvesting electrical energy while braking, comprising:
- moving a target relative to a platform, the platform having an energy harvesting brake system disposed therein;
- rotating a roller cylinder of the energy harvesting brake system with the movement of the target;
- cyclically stressing a piezoelectric material disposed in the energy harvesting brake system with the rotation of the roller cylinder;
- and
- generating electrical energy with the cyclically stressing the piezoelectric material.
An energy harvesting system, comprising:
- a first energy storage device;
- and
- an energy harvesting brake system electrically coupled to the first energy storage device, the energy harvesting brake system including:
- a shaft;
- a roller cylinder configured to rotate relative to the shaft;
- and
- a piezoelectric material 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.
