Abstract
A haptic device includes a flexible holder; an elongated piezo bender supported at one end thereof by the holder; a mass supported by the elongated piezo bender and positioned at an end of the elongated piezo bender opposite the end supported by the holder; and an electrical driving signal generator configured to generate a signal to create a vibration in the elongated piezo bender.
