Flexible tactile force reproduction device for wearable tactile force feedback

Abstract

The invention discloses a flexible tactile force reproduction device for wearable tactile force feedback. The device comprises a plurality of vibration modules distributed in an array, the outer sides of the plurality of vibration modules are provided with hydrogel layers, and each vibration module comprises a piezoelectric actuator, a supporting flexible part, a flexible substrate, an electromagnetic actuator and an electromagnetic actuator switch. The piezoelectric actuator is connected with positive and negative electrodes of a power supply and periodically vibrates up and down under the limitation of the supporting flexible part, the electromagnetic actuator is fixed on an upper end face of the piezoelectric actuator, a lower end face of the piezoelectric actuator is fixed on the supporting flexible part, the supporting flexible part is of a frame-shaped structure, the bottom of the supporting flexible part is fixedly connected with the flexible substrate, and the electromagnetic actuator switch is arranged at the bottom of the flexible substrate. The flexible tactile force reproduction device for wearable tactile force feedback is simple in structure and easy to process, simulation and reproduction of human skin tactile sense are achieved through the piezoelectric actuator and a reinforcing actuator, control is convenient, and the control precision is high.

Description

technical field [0001] The present invention relates to a novel flexible tactile force reproducing device capable of simulating human skin tactile feedback, in particular to a flexible tactile force reproducing device made of micro-actuators by superimposing flexible materials and electromagnetic elements. Background technique [0002] The traditional technologies of virtual reality (VR) and augmented reality (AR) reproduce the experience related to the real physical world for users by stimulating the visual and auditory senses. The most widely used VR and AR systems today use head-mounted displays, accelerometers, and speakers as the basis for computer-generated three-dimensional environments. Compared with vision and hearing, touch is a relatively unexplored field of perception in VR and AR technology, but It can greatly enhance the human body's ability to perceive environmental information, and it also has great application space in the fields of communication, entertainm...

AI Technical Summary

Problems solved by technology

Its design structure is relatively simple, the capacitance error formed by the electrode layer and the adjacent conductor is large, and the loss is large. In the structure, electrode pins are required to be connected, so that the flexibility of the entire electronic skin is limited, and the flexibility of real skin cannot be simulated.
