    摘要: An energy harvesting apparatus includes an inverse frequency rectifier structured to receive mechanical energy at a first frequency, and a solid state electromechanical transducer coupled to the inverse frequency rectifier to receive a force provided by the inverse frequency rectifier. The force, when provided by the inverse frequency rectifier, causes the solid state transducer to be subjected to a second frequency that is higher than the first frequency to thereby generate electrical power. The coupling of the solid state electromechanical transducer to the inverse frequency rectifier is a non-contact coupling.

    摘要: The invention is a magneto-optic coupled magnetic sensor that comprises a standard optical fiber Bragg grating system. The system includes an optical fiber with at least one Bragg grating therein. The optical fiber has at least an inner core and a cladding that surrounds the inner core. The optical fiber is part of an optical system that includes an interrogation device that provides a light wave through the optical fiber and a system to determine the change in the index of refraction of the optical fiber. The cladding of the optical fiber comprises at least a portion of which is made up of ferromagnetic particles so that the ferromagnetic particles are subject to the light wave provided by the interrogation system. When a magnetic field is present, the ferromagnetic particles change the optical properties of the sensor directly.

    摘要: A vascular implant, comprising a sheet comprising thin film nickel titanium (NiTi), wherein the sheet has at least one super-hydrophilic surface having a water contact angle of less than approximately 5 degrees. The sheet is configured to have a compacted form having a first internal diameter and a deployed form having a second internal diameter larger than the first internal diameter. The sheet may be delivered into a blood vessel in the compacted form and expanded to its deployed form at a treatment location within the blood vessel, wherein the stent is configured to expand onto an internal surface of the blood vessel and exert a radial force on said internal surface.

    摘要: The present invention discloses devices and a method of fabrication of devices using a shape memory effect, thin film with a compositional gradient through the thickness of the film. Specifically, a NiTi SME thin film is disclosed that can be used in actuators, MEMS devices and flow control. The process of fabrication includes a gradual heating of the target over time during the sputter deposition of a thin film on a substrate under high vacuum, without compositional modification. The resulting thin film exhibits two-way shape memory effect that can be cyclically applied without an external bias force.

    摘要: A novel energy harvesting system and method utilizing a thermoelectric having a material exhibiting a large thermally induced strain (TIS) due to a phase transformation and a material exhibiting a stress induced electric field is introduced. A material that exhibits such a phase transformation exhibits a large increase in the coefficient of thermal expansion over an incremental temperature range (typically several degrees Kelvin). When such a material is arranged in a geometric configuration, such as, for a example, a laminate with a material that exhibits a stress induced electric field (e.g. a piezoelectric material) the thermally induced strain is converted to an electric field.
