Latest Patents

One of his latest patents is for hydrocarbon sensing methods and apparatus. This invention features a sensor that utilizes a waveguide with a first cladding layer and a second cladding layer containing a measurement region with hydrophobic measurement material. Light is coupled into the waveguide, and the measurement material is exposed to hydrocarbons, allowing them to diffuse into it. This diffusion changes the refractive index of the material, which in turn alters the intensity of light evanescently coupled through the first cladding layer. The light measured through this layer determines the sensor's exposure to hydrocarbons.

Another significant patent involves a chip-scale, reusable sensor capable of detecting aromatic hydrocarbons, such as benzene, toluene, ethylbenzene, and xylenes (BTEX), rapidly in water without the need for sample preparation. This device allows for real-time, continuous monitoring of BTEX solutes, which diffuse into a film on the sensor's surface. The concentration of BTEX analytes in the film increases the refractive index, modulating evanescent coupling into the integrated photodetector array. This integration simplifies system instrumentation and reduces drift due to temperature fluctuations. The chip responds linearly for BTEX concentrations between 1 ppm and 30 ppm, with detection limits of 359 ppb, 249 ppb, and 103 ppb for benzene, toluene, and xylene in water, respectively.
