Meridian detection system based on localized bioelectrical impedance analysis, probe thereof, and operation method thereof

Abstract

This invention discloses a meridian detection system based on local bioelectrical impedance analysis, its probe, and its operation method. The system includes a probe with first and second detection electrodes spaced at a preset distance, a measurement circuit, and a microprocessor. The measurement circuit is configured to generate a high-frequency AC signal, which is applied to the local tissue of the test subject's skin detection point through the electrodes. This high-frequency AC signal can penetrate the high impedance characteristics of the stratum corneum of the skin, directly measuring the electrical response of deep tissues. Simultaneously, the fixed electrode spacing of the probe ensures the standardization and localization of the measurement current path. The microprocessor calculates an impedance value based on the electrical response.
