Latest Patents

One of her latest patents is the "Heat pumped parametric MEMS device." This invention involves a micro-electrical mechanical oscillator whose resonant frequency can be varied through the application of heat. The oscillator's resonant frequency is adjusted at a frequency different from its own to amplify oscillations. In this design, a disc of material is supported by a much smaller diameter pillar, and the disc's periphery is heated by a laser to create a time-varying shift in its resonant frequency. Feedback from the disc's movement modulates the laser intensity, allowing for parametric amplification of sensed vibrations.

Another notable patent is related to "Mechanically resonant nanostructures." This invention utilizes electron beam lithography to create very small mechanical structures in single-crystal silicon. The structures can be designed as a mesh with beam widths of less than 30 nm, suspended above a substrate. An RF drive voltage applied between the suspended structure and the substrate generates vibrations at or near the structure's resonant frequency. Optical interference techniques are employed to detect and measure these vibrations, providing high measurement sensitivity due to the suboptical-wavelength features of the mesh.
