Title: Qingyi Mu: Inventor of a Soil Measurement Calibration Method.
Introduction
Qingyi Mu is an inventor associated with Xi’an, China. Her work includes a patent for calibrating non-invasive time domain reflection probes used to measure soil moisture content and density.
Latest Patents
Mu’s listed patent is “Non-invasive time domain reflection probe calibration method and system.” The method uses ethanol and deionized water mixtures to determine the probes’ sensitivity to the test medium and their waveguide length. It also uses sodium chloride solutions to calibrate waveguide geometry, then tests compacted soil samples with known moisture contents and densities to establish correlations involving dielectric constant, conductivity, moisture content, and density. The approach is intended to support accurate soil measurements through a practical calibration process with broad applicability.
