Latest Patents
Cao's latest patents include a hydrogen sensor designed for detecting and quantifying hydrogen and hydrogen isotopes. This sensor features a sampling line and a microplasma generator that excites hydrogen from a gas sample, producing light emission from the excited hydrogen. A power supply powers the microplasma generator, while a spectrometer generates an emission spectrum from the light emission. A programmable computer is integrated to determine the presence of hydrogen and quantify the amount of hydrogen and/or hydrogen isotopes in the gas sample.
Another significant patent is an apparatus and method for monitoring diabetes through breath acetone detection and quantitation. This invention employs a microplasma source in combination with a spectrometer. The microplasma source provides sufficient energy to produce excited acetone fragments from the breath gas that emit light. The emitted light is directed to the spectrometer, which generates an emission spectrum used to detect and quantify acetone in the breath gas.
