Latest Patents

One of Sze's latest inventions is a compact device for sensing a liquid with energy harvesting from liquid motion. This device is designed to measure the absorption spectrum of liquids, such as water containing organic contaminants. It features an array of light-emitting diodes (LEDs) that emit light at unique spectral peaks. A specially shaped reflector forms a reference beam while allowing part of the emitted light to create a measurement beam after passing through the liquid. The device utilizes two photodetectors to measure both beams, providing reference and measured intensities for estimating the absorption spectrum. Notably, it harvests energy from the motion of the flowing liquid through wireless power transfer.

Another significant patent is a single-body unit for pulse oximeter calibration. This all-solid unit is composed of a flexible solid medium mixed with various materials, including scattering and dye materials. It is designed to emulate the absorbance characteristics of probe light beams due to pulsing arterial blood. The innovative design allows for the calibration of pulse oximeters without the need for additional devices, streamlining the calibration process.
