Patent number: 8695407Abstract: A microtensiometer sensor includes a substrate layer fluidly coupled to an enclosed reservoir. A porous membrane is disposed on a surface of the substrate layer. The membrane defines a liquid side fluidly coupled to the reservoir and a vapor side fluidly coupled to a vapor interface. The porous membrane includes a plurality of through holes fluidly coupling the liquid reservoir to the vapor interface, and a nanoporous filler material disposed within the plurality of through holes. The filler material includes a plurality of open pores having a maximum diameter in the range of 0.2 to 200 nanometers. In one embodiment, the microtensiometer sensor includes a molecular membrane disposed adjacent to the vapor side of the porous membrane. In one example, the molecular membrane is formed of a highly crystalline polytetrafluoroethylene polymer having a microstructure characterized by nodes interconnected by fibrils.Type: GrantFiled: April 16, 2010Date of Patent: April 15, 2014Assignee: Cornell UniversityInventors: Abraham D.

Patent number: 7691583Abstract: A system and method for detecting mass based on a frequency differential of a resonating micromachined structure, such as a cantilever beam. A high aspect ratio cantilever beam is coated with an immobilized binding partner that couples to a predetermined cell or molecule. A first resonant frequency is determined for the cantilever having the immobilized binding partner. Upon exposure of the cantilever to a solution that binds with the binding partner, the mass of the cantilever beam increases. A second resonant frequency is determined and the differential resonant frequency provides the basis for detecting the target cell or molecule. The cantilever may be driven externally or by ambient noise. The frequency response of the beam can be determined optically using reflected light and two photodetectors or by interference using a single photodetector.Type: GrantFiled: January 31, 2006Date of Patent: April 6, 2010Assignee: Cornell Research Foundation, Inc.Inventors: Harold G. Craighead, Bojan Ilic, David Alan Czaplewski, Robert H. Hall

Patent number: 7654140Abstract: A micro-electrical mechanical oscillator has a resonant frequency of oscillation that is varied by application of heat. The resonant frequency is varied at a frequency different from the resonant frequency of the oscillator to amplify oscillations. In one embodiment, the oscillator is disc of material supported by a pillar of much smaller diameter than the disc. The periphery of the disc is heated by a laser to provide a time varying shift of the resonant frequency (or equivalently the stiffness) of the disc. Feedback from movement of the disc is used to modulate the intensity of the laser, and thus the stiffness of the disc to provide parametric amplification of sensed vibrations, using heating as a pump. Various other shapes of micro-electrical mechanical oscillators are used in other embodiment, including an array of such oscillators on a substrate, each having different resonant frequencies.Type: GrantFiled: March 12, 2002Date of Patent: February 2, 2010Assignee: Cornell Research Foundation, Inc.Inventors: Maxim Zalalutdinov, Anatoli Olkhovets, Alan T.

Publication number: 20060219010Abstract: Prefabricated catalyzing adsorption sites are incorporated into small oscillators. In one embodiment, the sites are formed of precisely positioned gold anchors on surface micromachined oscillators. The micromachined oscillators may be formed of silicon, such as polysilicon, or silicon nitride in various embodiments. The sites allow special control of chemical surface functionality for the detection of analytes of interest. Thiolate molecules may be adsorbed from solution onto the gold anchors, creating a dense thiol monolayer with a tail end group pointing outwards from the surface of the gold anchor. This results in a thiolate self-assembled monolayer (SAM), creating a strong interaction between the functional group and the gold anchor.Type: ApplicationFiled: March 29, 2005Publication date: October 5, 2006Inventors: Bojan Ilic, Harold Craighead

Publication number: 20050180678Abstract: A substrate incorporates a mechanical cantilever resonator with passive integrated optics for motion detection. The resonator acts as a waveguide, and enables optical detection of deflection/displacement amplitude, including oscillations. In one embodiment, the cantilever comprises a silicon waveguide suspended over a substrate. A reflector structure faces a free end of the suspending cantilever, or a waveguide is supported facing the free end of the suspended cantilever to receive light transmitted through the silicon waveguide cantilever. Deflection/displacement of the cantilever results in modulation of the light received from its free end that is representative of the displacement. Ring resonators may be used to couple different wavelength light to the waveguides, allowing formation of an array of cantilevers.Type: ApplicationFiled: February 18, 2004Publication date: August 18, 2005Inventors: Roberto Panepucci, Bojan Ilic, Michal Lipson, Vilson Almeida
