Abstract
Systems, methods, and computer-readable media are disclosed for haptic feedback devices with reduced power consumption. In one embodiment, an example device may include a first spring, a mass coupled to the first spring, and a resonant piezoelectric actuator coupled to the first spring. The resonant piezoelectric actuator may be configured to impart a force on the mass via the first spring responsive to an applied voltage. The device may include a power source configured to supply the applied voltage to the resonant piezoelectric actuator, where motion of the mass generates vibration.
