  • Sensor including mechanical resonator with nano-structured surface
    Patent number: 10495607
    Abstract: A dissipation-based sensor includes a single resonator with a nano-structured surface. The sensor exhibits improved sensitivity, up to about 2 orders of magnitude higher than a single resonator without a nano-structured surface. The sensor operates by measuring and estimating the fluid friction per oscillation cycle, operating in normal conditions without vacuum (e.g., in air or other ambient gas) at room temperature. The sensor can provide measurement data at a speed that is orders of magnitude faster than pre-existing resonance-based methods, as it is based on measurements from a few cycles only. The dissipation-based sensor may be utilized in a broad range of fast, inexpensive, hand-held measuring devices. Additionally, the sensor is capable of operating at standard temperature and pressure.

  • Photo-patternable multifunctional polymer nanocomposite
    Patent number: 9146463
    Abstract: The invention provides a photo-patternable multifunctional polymer nanocomposite. The nanocomposite comprises a solvent suspension of multiferroic nanostructures uniformly dispersed in SU-8 polymer matrix. The invention also provides a composite comprising a substrate and a photo-patterned multifunctional polymer nanocomposite layer formed on the substrate. The nanocomposite layer comprises a UV-photolithographed SU-8 polymer having a solvent suspension of multiferroic nanostructures uniformly dispersed in the polymer matrix.
