摘要:
A method of assembly of micro-scale objects includes forming a pattern of a first functional moiety on a surface of a substrate, contacting the surface of the substrate with a first liquid suspension including first micro-scale feedstock elements functionalized with a second functional moiety, complimentary to the first functional moiety, on first portions of the first micro-scale feedstock elements and functionalized with a third functional moiety on second portions of the first micro-scale feedstock elements, aligning the first portions of the first micro-scale feedstock elements with the surface of the substrate, and facilitating bonding the second functional moieties to the first functional moieties to form a first microstructure pattern of the first micro-scale feedstock elements on the surface of the substrate.
摘要:
A chip scale star tracker that captures plane-wave starlight propagating in free space with a wafer-thin angle-sensitive broadband filter-aperture, and directs the light into a waveguide structure for readout. Angular information about the star source is determined from characteristics of the starlight propagating in the waveguide. Certain examples include internal propagation-constant-based baffling to elimination stray light from extreme angles.

The systems and methods disclosed herein are generally related to a cell culture system. More particularly, the systems and methods enable the culturing and interconnecting of a plurality of tissue types in a biomimetic environment. By culturing organ specific tissue types within a biomimetic environment and interconnecting each of the organ systems in a physiologically meaningful way, experiments can be conducted on in vitro cells that substantially mimic the responses of in vivo cell populations. In some implementations, the organ systems are fluidically connected with a constant-volume pump.

A microfluidic device for increasing convective clearance of particles from a liquid is provided. A network of first channels can be separated from a network of second channels by a membrane. The network of second channels can include a pressurizing feature to create a high pressure at an upstream portion of the second channels and a low pressure at a downstream portion of the second channels. Liquid containing an analyte can be introduced in the network of first channels. Filtrate can be flowed through the pressurizing feature in the second channels, such that the pressure difference in between the first and second channels causes at least some of the analyte in the first liquid is transported into the second channels through the membrane.

An electronic module comprises a substrate having a plurality of cavities. A die is encapsulated within each cavity. A post defines at least a portion of an electrical connection through the substrate.
摘要:
In various embodiments, an electronic module features a first cavity in a first side of a substrate, a fill hole extending from the first cavity, and a second cavity in a second side of the substrate. The second cavity is in fluidic communication with the fill hole, and a die is encapsulated within the second cavity.
摘要:
A suspension of a chip-scale device is accomplished using a suspension frame and at least one first tether. The chip-scale suspension frame defines a first plane and an opening through the suspension frame. At least one first tether crosses the opening at a first angle relative to the first plane and can be used to position the chip-scale device at least partially within the opening.
摘要:
A method for manufacturing a flexural plate wave sensor includes the steps of depositing an etch-stop layer (34) over a substrate (32), depositing a membrane layer (36) over the etch stop layer, depositing a piezoelectric layer (38) over the membrane layer, forming a first transducer (44) on the piezoelectric layer and forming a second transducer (48) on the piezoelectric layer, spaced from the first transducer. The method further includes the steps of etching a cavity (52) through the substrate, the cavity having substantially parallel interior walls (54a, 54b), removing the portion of the etch stop layer between the cavity and the membrane layer to expose a portion (53) of the membrane layer, and depositing an absorptive coating (56) on the exposed portion of the membrane layer.
