Embodiment Construction

[0047] The high-focus multi-channel transcranial direct current electrical stimulation device and control method proposed by the present invention include a hardware module and a parameter optimization module.

[0048] a) Hardware module

[0049] As attached Figure 4 Shown in is the multi-channel tDCS electrode array proposed in this scheme. The tDCS electrode array is based on the 10-20 international electrode placement method with multi-channel tDCS electrodes on the surface of the skull. The electrode polarity and current intensity are separately controlled by multiple independent units. Unlike the existing tDCS system, this solution can achieve multi-channel stimulation in the entire head.

[0050] Different from the 25-35 cm2 square electrode usually used in the existing tDCS system, the circular electrode less than 5 cm2 will be used in the design of this scheme. Studies have shown that the use of square electrodes will cause the current to be concentrated in the four corner...

Abstract

The invention discloses a high-focusing-capability multi-channel transcranial direct current stimulation device and a control method thereof. The high-focusing-capability multi-channel transcranial direct current stimulation device comprises a transcranial direct current stimulation (tDCS) electrode array, a power source and control units, wherein channel electrodes in the electrode array are connected with the power source respectively through independent control units, polarity and current strength of the channel electrodes are respectively controlled through the independent control units, and the tDCS electrode array is integrated into an electrode cap mode. The high-focusing-capability multi-channel transcranial direct current stimulation device can complete automatic optimization of stimulation parameters of the channels according to stimulation positions and types specified by users, and finally generates stimulation meeting users' requirements. A tDCS system of the high-focusing-capability multi-channel transcranial direct current stimulation device has the advantages of being capable of covering the whole head, having high focusing capability and multiple channels and the like, and is accurate in stimulation position and customizable in complex stimulation.

Description

technical field [0001] The invention belongs to biomedical technology, and in particular relates to a novel transcranial direct current stimulation device and a control method. Background technique [0002] Transcranial direct current stimulation (tDCS) is a non-invasive method to regulate the excitability of the cerebral cortex. In foreign countries, systematic research on tDCS began in the 1960s. With the recent increase in the understanding of the function and pathology of the central nervous system, tDCS has become a research hotspot again in recent years. In tDCS, a pair of square positive and negative electrodes with a size of 25-35 cm2 are attached to the epidermis of the skull and a weak direct current of 1-2 mA is introduced for 10-20 minutes. The current of tDCS flows from positive to negative, part of the current passes through the scalp, and part of The brain, by stimulating the cerebral cortex, regulates the excitability of the cerebral cortex. Studies have sh...
