Latest Patents

Luhua Cheng holds a patent for a "Double-sided diaphragm micro gas-preconcentrator with a back-on-face configuration." This invention features a micro-gas chamber created by stacking an upper silicon substrate with a lower silicon substrate. The design includes one or more suspended membranes on each silicon substrate, with the silicon beneath the membranes completely removed to form a cavity. A thin-film heater is deposited on each suspended membrane, and a sorptive film is coated on the inner wall of every suspended membrane. This innovative configuration improves the area of the sorptive film on the diaphragm, enhancing the preconcentrating factor while maintaining a small heat capacity, fast heating rate, and low power consumption.
