    摘要： A connector assembly and method of attaching the same to one or more biosensor module boards. The connector assembly includes a body portion defining a first surface and a second surface opposite the first surface. The connector assembly also includes a coaxial RF connector positioned in the body portion and extending between the first surface and the second surface. The coaxial RF connector includes a ground ring, an RF pin positioned within the ground ring, and dielectric therebetween. The connector assembly is configured to be coupled to an RF detection board such that the coaxial RF connector is operably coupled thereto. The connector assembly is also configured to be connected to a biosensor module board such that the coaxial RF connector is operably connected thereto.

    摘要： The present disclosure provides a method for determining a property of a test substance. The method may comprise first encoding the test substance as a wave through a non-solid medium by chemical excitation before processing the wave through the non-solid medium, wherein the processing modifies one or more features of the wave into one or more processed wave features according to one or more conditions of the non-solid medium. The one or more processed wave features are decoded to determine one or more features of the test substance.

    摘要： A multimodal optical technique that can measure the mechanical, optical, and acoustical properties of the sample at microscopic resolution, which is based on the integration of a Brillouin microscope and a photoacoustic (PA) microscopy is provided. The multimodal technique not only can acquire co-registered Brillouin and PA signals of the sample but also allows us to utilize the sound speed measurements by PA to quantify the sample's refractive index, which is an essential property of the material and cannot be measured by either technique individually. We demonstrated the colocalization of Brillouin and time-resolved PA signals by measuring the interface of kerosene and 1% CuSO4 aqueous solution. In addition, we measured the refractive index of saline solutions with a precision of 0.003 and validated the result against published data. This multimodal modality could open new way for charactering biological cell and tissue in physiological and pathological conditions.

    摘要： Methods of fabricating a bulk acoustic wave resonator structure for a fluidic device. The methods can include a first step of disposing a first conductive material over a portion of a first surface of a substrate to form at least a portion of a first electrode, the substrate having a second surface opposite the first surface. Then, a piezoelectric material may be disposed over the first electrode. Next, a second conductive material can be disposed over the piezoelectric material to form at least a portion of a second electrode. The second conductive material extends substantially parallel to the first surface of the substrate and the second conductive material at least partially extends over the first conductive material. The overlapping region of the first conductive material, the piezoelectric material, and the second conductive material form a bulk acoustic wave resonator, the bulk acoustic wave resonator having a first side and an opposing second side. An acoustic energy management structure is then disposed over a first side of the bulk acoustic wave resonator. Next a third conductive material is disposed over a portion of the second conductive material that extends beyond the bulk acoustic wave resonator, wherein the third conductive material forms an interconnect extending above the acoustic energy management structure in a direction substantially perpendicular to the first surface of the substrate. Finally a portion of the second surface of the substrate is removed to expose a chemical mechanical connection at the first electrode at a second side of the bulk wave acoustic resonator. Devices formed thereby are also included.

    摘要： An acoustic wave sensor device comprises a first interdigitated transducer, a first reflection structure, a second reflection structure, a first resonance cavity comprising a first upper surface and formed between the first interdigitated transducer and the first reflection structure, and a second resonance cavity comprising a second upper surface and formed between the first interdigitated transducer and the second reflection structure. At least one of the first and second upper surfaces is covered at least partly by a metalization layer or a passivation layer. The present invention relates also to an acoustic wave sensor assembly.
