Abstract:
Erfindungsgemäß wird ein Verfahren zur Herstellung eines mit Nanodrähten strukturierten Substrats bereitgestellt, das dadurch gekennzeichnet ist, dass in dem Verfahren kein Gleitmittel und keine lithographische Lackmaske verwendet wird und nur durch das Bewegen eines Donorsubstrats mit Nanodrähten relativ zu einem Substrat und lokal unterschiedliche tribologische Eigenschaften auf der Oberfläche des Substrats selektiv an lokal definierten Stellen des Substrats eine bestimmte Anzahl Nanodrähte abgelegt wird. Zudem wird ein Substrat bereitgestellt, das durch das erfindungsgemäße Verfahren herstellbar ist und an einer Oberfläche selektiv an lokal definierten Stellen eine bestimmte Anzahl Nanodrähte enthält. Ferner wird die Verwendung des erfindungsgemäßen Substrats in der Mikroelektronik, Mikrosystemtechnik und/oder Mikrosensorik vorgeschlagen.
Abstract:
The disclosed embodiments provide sensitive pixel arrays formed using solvent-assisted or unassisted release processes. Exemplary devices include detectors arrays, tunable optical instruments, deflectable mirrors, digital micro-mirrors, digital light processing chips, tunable optical micro-cavity resonators, acoustic sensors, acoustic actuators, acoustic transducer devices and capacitive zipper actuators to name a few.
Abstract:
The disclosure provides methods and apparatus for release-assisted microcontact printing of MEMS. Specifically, the principles disclosed herein enable patterning diaphragms and conductive membranes on a substrate having articulations of desired shapes and sizes. Such diaphragms deflect under applied pressure or force (e.g., electrostatic, electromagnetic, acoustic, pneumatic, mechanical, etc.) generating a responsive signal. Alternatively, the diaphragm can be made to deflect in response to an external bias to measure the external bias/phenomenon. The disclosed principles enable transferring diaphragms and/or thin membranes without rupturing.

Micro fluidic devices comprising three dimensional elements fabricated onto a substrate using thick film printing technology, e.g., screen printing, wherein the three dimensional elements possess both structural and functional properties.
Abstract:
Disclosed are methods of lithography using a tip array having a plurality of pens attached to a backing layer, where the tips can comprise a metal, metalloid, and/or semi-conducting material, and the backing layer can comprise an elastomeric polymer. The tip array can be used to perform a lithography process in which the tips are coated with an ink (e.g., a patterning composition) that is deposited onto a substrate upon contact of the tip with the substrate surface. The tips can be easily leveled onto a substrate and the leveling can be monitored optically by a change in light reflection of the backing layer and/or near the vicinity of the tips upon contact of the tip to the substrate surface.

Abstract:
Systems and methods of nanomaterial transfer are described. A method of nanomaterial transfer involving fabricating a template and synthesizing nanoparticles on the template. Subsequently, the nanoparticles are transferred to a substrate by pressing the template onto the substrate. In some embodiments, the step of transferring the nanoparticles involves pressing the template onto the substrate such that the nanoparticles are embedded below a surface layer of the substrate. In some embodiments, the temperature of the plurality of nanoparticles is raised to assist the transfer of the nanoparticles to the substrate.
