Abstract

This paper introduces a 16-channel multimodal high-precision transcranial electrical stimulation system specifically for non-invasive brain stimulation. This system added TMCS mixed four traditional stimulation modes with TACS, TDCS, TPCS and TRNS. By designing a compensated high-precision constant current source, the constant stimulation current with an accuracy of 0.03 mA in the range of ±2 mA and the stimulation frequency of 50~200 kHz with low frequency of 0~4 kHz (high frequency of 0.1 Hz) are realized. In TACS stimulation mode, there are five adjustable wave forms: triangular wave, sine wave, sawtooth wave, square wave and mixed wave. The system has dual closed-loop control overcurrent detection and simultaneous real-time electrode contact impedance detection. After relevant tests and verification, the system has good stimulation accuracy, high safety and reliability. Compared with the existing products at home and abroad, it features lower cost, richer stimulation mode and waveforms, demonstrating a certain market application value.

[16通道多模态高精度经颅电刺激系统的开发]。

介绍了一种专门用于无创脑电刺激的16通道多模态高精度经颅电刺激系统。该系统增加了TMCS，混合了TACS、TDCS、TPCS和TRNS四种传统刺激模式。通过设计补偿型高精度恒流源，实现了在±2 mA范围内0.03 mA的恒定激励电流和50~200 kHz的激励频率，低频0~4 kHz（高频0.1 Hz）。在TACS刺激模式下，有五种可调波形：三角波、正弦波、锯齿波、方波和混合波。该系统具有双闭环控制过流检测和同步实时电极接触阻抗检测功能。经过相关测试和验证，该系统具有较好的增产精度，安全性和可靠性高。与国内外现有产品相比，成本更低，刺激方式和波形更丰富，具有一定的市场应用价值。
