Latest Patents

Fang's latest patents include a method for measuring free radicals based on the conductivity change of conductive polymers. This innovative method involves providing a sensor that includes a substrate and a conductive polymer layer. The conductive polymer layer is configured on the substrate and is made of conductive polymer. By applying a liquid sample containing free radicals to the sensor, the conductivity of the conductive polymer layer decreases due to oxidation caused by the free radicals. The concentration of free radicals in the liquid sample can then be calculated based on the conductivity change rate before and after the sample is applied. This invention is advantageous due to its low cost, small size, and ease of operation, making it suitable for detecting hydroxyl radicals in oxidative stress studies.

Another significant patent by Fang is a transistor-type viscosity sensor, along with a viscosity measurement system and method. This system is designed for measuring the viscosity of fluids and comprises a transistor-type viscosity sensor, an electrical measurement unit, and a processing unit. The sensor includes a semiconductor structure with a GaN layer and an AlGaN layer. The portion of the semiconductor structure between the source and drain terminals has a gate region that contacts the fluid. The electrical measurement unit is connected to the source and drain terminals to measure the electronic signal of the semiconductor structure. The processing unit determines the viscosity of the fluid based on the measured electronic signal.
