Abstract

Provided is a piezoelectric type tactile sense feedback actuator. The actuator comprises a support, n quasi-ciliary body type touch beams, 2n piezoelectric ceramic pieces, a controller and a battery, wherein n is a natural number larger than or equal to 3; the quasi-ciliary body type touch beams are parallelly mounted on the support, the controller and the battery are mounted on a bottom platform of the support, and the battery is used for providing electricity for the actuator; a pair of piezoelectric ceramic pieces are bonded on the upper surface and the lower surface of each quasi-ciliary body type touch beam; each piezoelectric ceramic piece is connected with the controller through a secondary amplifier circuit, a see-saw circuit and an AD switching module; the controller outputs sinusoidal signals of which the frequency is identical to that of the original mode of the quasi-ciliary body type touch beams, the piezoelectric ceramic pieces compel the quasi-ciliary body type touch beams to bend and vibrate and make the vibration directions of ciliary body structures tend to be same, and accordingly the tactile senses of different roughnesses in two directions are generated. The piezoelectric type tactile sense feedback actuator makes fingers of a person feel different tactile senses by changing the moving direction of the fingers, the frequency of exciting signals and the quasi-ciliary body distribution structures.

Description

technical field [0001] The invention belongs to the technical field of tactile feedback applications, and in particular relates to a piezoelectric tactile feedback actuator. It has a broad application space in the fields of tactile display, virtual reality, human-computer interaction, biomedicine, and robotics. Background technique [0002] Human-computer interaction technology has developed rapidly in recent years, and has been widely used in medical, military, entertainment and other fields. However, the current human-computer interaction technology focuses on the reproduction and simulation of sound and vision, and the research on tactile channel information transmission is still in its infancy. Therefore, the development and research of tactile devices is one of the important directions for the development of human-computer interaction technology. [0003] Piezoelectric touch feedback devices use the inverse piezoelectric effect of piezoelectric ceramic materials to con...
