Electrostimulation system for artificial electrotactile sensation

Abstract

The invention provides an electrical stimulation system for producing artificial electric touch. The electrical stimulation system comprises an electrical stimulation pulse output device and a plurality of electrode arrays, wherein a command of the control party is received by the electrical stimulation pulse output device to produce corresponding electrical stimulation pulse, and the electrical stimulation pulse output device comprises a command receiver, a controller and an electrical stimulator; the command is converted into a digital signal to be output to the controller by the command receiver; corresponding electrodes are selected by the controller in the electrode arrays according to the received command signal, and the produced needed stimulation pulse characteristic is sent to the electrical stimulator; the stimulation pulse is output to the corresponding electrode in the electrode array by the electrical stimulator according to the received stimulation pulse characteristic; and the electrode array is contacted with finger pulp skin to output the electric stimulation pulse so as to stimulate a mechanical receptor in the skin to produce nervous impulse to produce touch. The electrical stimulation system is various in stimulation modes, vivid in touch representation, convenient to use, wide in applicable range, safe, effective and small in side effect.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to an electric stimulation system for generating artificial electric touch. Background technique [0002] Touch is one of the human senses. Although compared with vision and hearing, the proportion of information obtained by touch is very small, but it is worth affirming that in the process of human understanding of the objective world, touch plays a vital role in human detection of things. Especially for the detection of the texture and texture of objects, the sense of touch is almost the only means of detection. [0003] In the field of remote control robots, the operator can obtain more information through the tactile channel, especially when grasping objects of different materials and shapes, the operator can reasonably control the grip force of the robot arm. When performing telemedicine operations, after introducing artificial touch, the chief surgeon can have a more realis...

Problems solved by technology

This electrical stimulation device is equivalent to a graphic reader used by the blind, focusing on the distribution of stimulation positions in the electrode array. However, the stimulation mode is single, and it is difficult to stimulate the four types of mechanoreceptors separately, and it cannot truly reproduce the physiological touch of the human body.
