Somatosensory touch excitation generator

Abstract

A somatosensory touch excitation generator comprises a stepping motor, a set of magnetically-operated mechanisms, a set of guide rail sliding block mechanisms and a constant frequency control unit. The output end of an upper computer of the constant frequency control unit is connected with the input end of a wireless transmitting module. The stimulus frequency is transmitted to the wireless signal transmitting module through the upper computer, and then the data are transmitted through the output end of the wireless transmitting module, received by the input end of a wireless receiving module and transferred to a micro-control module through the output end of the wireless receiving module. The micro-control module generates pulse signals of certain frequency after calculation and controls rotation of magnetic steel of the magnetically-operated mechanisms, and therefore magnets move vertically and generate the touch excitation effect. According to the somatosensory touch excitation generator, accurate and adjustable low frequency touch vibration excitation capable of being felt by the human body is adopted, the power source is stable and reliable, the frequency is accurate and adjustable, wounds brought in the use process can be avoided, and various kinds of accurate frequency somatosensory touch excitation are flexibly provided. The somatosensory touch excitation generator is simple in structural design, high in integration level, low in noise and convenient to carry.

Description

technical field [0001] The invention relates to a somatosensory tactile device, in particular to a somatosensory tactile excitation generator. Background technique [0002] As an important sensory organ of human beings, the skin is a very sensitive receptor with very dense contacts, and the resolution of contacts varies in different parts of the body. Humans can obtain two basic sensations through contact or touch (including vibration, touch, pain, etc.): somatosensory and proprioceptive. Somatoception provides us with information about object shape, surface texture or roughness, and temperature; proprioception is the internal force and movement of muscles felt by muscles and tendons, thereby obtaining in-depth information about object shape, strength, and hardness. It can be seen that the special sensory organ of the skin has an irreplaceable role and efficacy that other functional organs cannot replace.

Problems solved by technology

[0013] It is not difficult to find from the survey that the above-mentioned types of somatosensory stimulation generating devices are either expensive and complicated; or the stimulation is simple, the effect is poor, the frequency is too high or too low, the cost performance is low, and the flexibility is not very good.
