Abstract: Methods, systems, and devices are disclosed for applying motion stimulations on a body using actuators. In one aspect, a device to provide mechanical stimulation to a user includes an apparel material capable of being worn by a user, a flexible material substrate configured at a portion or region of the apparel material, an actuator module attached to the flexible material substrate and structured to include an array of piezoelectric actuators to apply mechanical perturbations at a frequency to the user wearing the apparel material, and a power supply module electrically coupled to the actuator module to provide electrical power to the actuator module. The actuator module may be located within one of a pillow, seat, bed and stuffed animal, or it may be in physical connection with one of wearable apparel, bedding, cloth and blankets.
