Latest Patents

One of his latest patents is titled "Advanced Calorimetric Spectroscopy for Commercial Applications of Chemical and Biological Sensors." This invention includes a chemical and biological sensor system that features at least one micro-cantilever sensing element. The system is designed to collect aerosol, liquid, and solid particles, depositing them as a film layer on a stack formed with the cantilever. The deposited particles consist of chemical or biological species that require analysis. A polarized light illuminates the stack at a grazing incidence angle, heating the cantilever with different wavelengths of the light spectrum. The readout electronics detect the movement of the cantilever due to heat transfer from the light, providing spectral data signals that correspond to the detected movement. A spectral analyzer then analyzes these signals, comparing them to known materials to identify the chemical or biological species present.

Another significant patent is for an "Anti-Reflective Structure." This invention is designed to form a surface that transmits incident light with minimal losses. The anti-reflective surface features a plurality of protrusions with a size smaller than the wavelength of the incident light. These protrusions increase in height in either a sloped linear or curvilinear manner, repeating across the surface to enhance light transmission. The use of gray scale lithography allows for the production of these patterns in photoresist layers, achieving transmission values as high as 99.3%.
