摘要:
A micromechanical particle sorting chip uses laser light directed through at least one of a reflective and refractive surface to come to a focus in an optically transparent layer. The laser light impinges on a particle of interest, causing it to fluoresce. Upon detecting the fluorescence, a micromemchanical actuator is activated, which directs the particle of interest into one of a plurality of possible exit paths.
摘要:
A micromechanical particle sorting chip uses an actuator divided into two parts to direct a component of interest into one of a plurality of possible exit paths, based on detection of a fluorescent signal emanating from the component of interest. The two-part actuator may include a force-generating portion and a microactuator portion. The microactuator portion may be disposable, whereas the force-generating portion may be reuseable. By bringing the force-generating portion into proximity to the microactuator portion, the microactuator is induced to move, thereby separating the component of interest from the rest of the fluid stream. The force-generating portion and the microactuator portion may be optimized and fabricated separately, thereby leading to faster, more reliable and less expensive particle sorting.

A microfabricated cross flow filter may have multiple filtration stages. The filtration stages may include microfabricated filter barriers and gaps created in a substrate, thereby allowing very tight tolerances in the filter barrier and gap dimensions to be maintained. Using the microfabrication techniques, the filter barriers can be made having arbitrary shapes, and arranged at an angle or curved with respect to the flow direction, making the pressure drop across the filtration stage more uniform in the cross flow direction.

The invention describes a method and apparatus for deploying micromachined actuators in a plane which is orthogonal to the original fabrication plane of the devices. Using batch-processing, photolithographic procedures known in the micromachined electromechanical system (MEMS) art, a plurality of devices is constructed on a suitable substrate. The devices are then separated one from another by sawing and dicing the original fabrication wafer. The devices are rotated into an orthogonal orientation and affixed to a second wafer. The second wafer also contains circuitry for addressing and manipulating each of the devices independently of the others. With this method and apparatus, arrays of actuators are constructed whose plane of actuation is perpendicular to the plane of the array. This invention is useful for constructing N×M fiber optic switches, which direct light from N input fibers into M output fibers.

Traveling-wave directional filters (DFs) with multiple coupling slots are disclosed. A traveling-wave directional filter may include two terminating conductive strips in a top circuit layer of a substrate, a loop resonator in a bottom layer of a substrate, and a shared ground plane. Coupling slots in the ground plane may couple the conductive strips via the loop resonator.
