Abstract:
Laminates (600) having microfluidic structures (615-635) disposed between sheets (605-610) of the laminate (600) are provided. The microfluidic structures (615-635) are raised on a sheet (605, 610) of the laminate (600), typically by printing the structure (615-635) on the sheet (605, 610). Printing methods include Serigraph, ink-jet, intaligo, offset printing and thermal laser printing.
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.
Abstract:
The embodiments disclosed herein are directed to fabrication methods useful for creating MEMS via microcontact printing by using small organic molecule release layers. The disclose method enables transfer of a continuous metal film onto a discontinuous platform to form a variable capacitor array. The variable capacitor array can produce mechanical motion under the application of a voltage. The methods disclosed herein eliminate masking and other traditional MEMS fabrication methodology. The methods disclosed herein can be used to form a substantially transparent MEMS having a PDMS layer interposed between an electrode and a graphene diaphragm.
Abstract:
The invention relates to a method for printing a nanostructure and/or microstructure (5) on a substrate (1) having a three-dimensional macro-surface (6). The method is characterized in that a substance (12, 13) is applied having a three-dimensional stamp macro-surface (10), the shape of which matches the macro-surface (2) of the substrate (1) at least in some sections and which is provided with a stamp nanostructure and/or microstructure (10), and the stamp (4) is positioned relative to a substrate (1), and the stamp (4) and substrate (1) are brought together, thus printing the substance (12, 13) as a nanostructure and/or microstructure (5) onto the substrate (1). The invention further relates to a stamp (4) for carrying out the method, and to a substrate (1) produced with said method.
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.
Abstract:
Embodiments of the present disclosure digital microfluidic arrays that may be fabricated by a printing method, whereby digital microfluidic electrodes arrays are printed, via a printing method such as inkjet printing, onto a suitable substrate. In some embodiments, a substrate and/or ink is prepared or modified to support the printing of electrode arrays, such as via changes to the surface energy. In some embodiments, porous and/or fibrous substrates are prepared by the addition of a barrier layer, or, for example, by the addition or infiltration of a suitable material to render the surface capable of supporting printed electrodes. Various example embodiments involving hybrid devices formed by the printing of digital microfluidic arrays onto a substrate having a hydrophilic layer are disclosed.
