| 摘 要： | 穴位点的确定是针灸及相关物理治疗的重要环节。根据穴位电阻抗的特异性，利用阻抗测量原理，设计了一种基于单片机的穴位探测电路。包括生物阻抗检测电路、模／数转换、单片机控制及结果显示等部分，并利用该探测电路进行了太阳穴、合谷穴、人中穴等穴位的实验测试。实验结果表明，该电路能较准确地确定穴位的位置。

| Abstract: | Recognition of acupuncture points is a key step for acupuncture therapy and other corresponding physical treatment. Based on the electrical impedance property of acupuncture points, a bio-impedance detection circuit is designed to measure acupuncture points. The system consists of impedance detection circuit, A/D convertor, impedance computation and LED display. Experiment results suggests that the proposed system can be used for acupuncture points detection. |
