Abstract:
Systems and methods are provided that facilitate the formation of micro-mechanical structures and related systems on a laminated substrate. More particularly, a micro-mechanical device and a three-dimensional multiple frequency antenna are provided for in which the micro-mechanical device and antenna, as well as additional components, can be fabricated together concurrently on the same laminated substrate. The fabrication process includes a low temperature deposition process allowing for deposition of an insulator material at a temperature below the maximum operating temperature of the laminated substrate, as well as a planarization process allowing for the molding and planarizing of a polymer layer to be used as a form for a micro-mechanical device.
Abstract:
Systems and methods are provided for patterning biological and non-biological material at specific sites on a plate, as well as growing three dimensional structures. Preferred embodiments comprise a plate with regions that will trap gas, usually in the form of bubbles, when the plate is submerged in liquid. Other embodiment of the present invention include a method for placing materials on the plate at pre-determined locations through the use of trapped gas to prevent materials from collecting at unwanted regions. The plate has great utility for plating cells and tissues at specific sites, such as on an array. The disclosed method can also be used to coat the surface of a plate with coatings at specific locations for patterned coating applications and to build up materials to produce three dimensional structures, including micro-mechanical structures—where the structures may be formed from living or non-living material, tissue or non-tissue, organic or inorganic, and the like.
Abstract:
Magnetically actuated micro-electro-mechanical capacitor switches in laminate are disclosed. According to one embodiment, an apparatus comprises a first layer comprising a coil and magnetic element, the magnetic element made from one of nickel and iron; a second layer comprising a flexible member, wherein a permanent magnet is attached to the flexible member; a conductive plate having an insulating dielectric coating, the conductive plate attached to one of the flexible member or a magnet; and a third layer comprising a transmission line and magnetic material, wherein the transmission line comprises one or more of a signal conductor and one or more ground conductors in near proximity.
Abstract:
The methods described herein provide for a radio frequency micro-electromechanical systems switch having two or more resonant frequencies. The switch can be configured as a capacitive shunt switch having a deflectable member coupled between two electrodes over a transmission line. A first insulator can be located between one of the electrodes and the deflectable member to form a capacitive element. The deflectable member can be deflectable between an up-state and a down-state, the down-state capacitively coupling the deflectable member with the transmission line. The degree by which the deflectable member overlaps the first insulator can be adjusted to adjust the capacitance of the capacitive element and the resulting resonant frequency.

Abstract:
A plate manufactured to enable samples of cells, micro-organisms, proteins, DNA, biomolecules and other biological media to be positioned at specific locations or sites on the plate for the purpose of performing addressable analyses on the samples. Preferably, some or all of the sites are built from a removable material or as pallets so that a subset of the samples of interest can be readily isolated from the plate for further processing or analysis. The plate can contain structures or chemical treatments that enhance or promote the attachment and/or function of the samples, and that promote or assist in their analyses.
Abstract:
A directionally-sensitive device for detecting and processing vibration waves includes an array of polymeric optical waveguide resonators positioned between a light source, such as an LED array, and a light detector, such as a photodiode array. The resonators which are preferably oriented substantially perpendicularly with respect to incoming vibration waves, vibrate when a wave is detected, thus modulating light signals that are transmitted between the light source and the light detector. The light detector converts the modulated light into electrical signals which, in a preferred embodiment, are used to drive either the speaker of a hearing aid or the electrode array of a cochlear implant. The device is manufactured using a combination of traditional semiconductor processes and polymer microfabrication techniques.
Abstract:
Systems and methods are providing for performing high-throughput, programmable, multiplexed assays of biological, chemical or biochemical systems. Preferably, a micro-pallet includes a small flat surface designed for single adherent cells to plate, a cell plating region designed to protect the cells, and shaping designed to enable or improve flow-through operation. The micro-pallet is preferably patterned in a readily identifiable manner and sized to accommodate a single cell to which it is comparable in size. Each cell thus has its own mobile surface. The cell can be transported from place to place and be directed into a system similar to a flow cytometer. Since, since the surface itself may be tagged (e.g., a bar code), multiple cells of different origin and history may be placed into the same experiment allowing multiplexed experiments to be performed.
