Hydraulically actuated micro-contact printing engines

چکیده
Micro-contact printing (μCP) is a rapid, simple and well-established method of microscale biochemical patterning. However, there is a lack of inexpensive and accessible tools for accurately controlling contact during the printing process. In this paper, controlled μCP using hydraulic actuation is demonstrated. Complete printing systems, including a substrate placed at a calibrated height above an elastic stamp attached to a hydraulic chuck, are constructed and characterized. The chucks are made from Perspex using precision machining while the stamp is made by casting against microfabricated silicon masters. The total patterned area is ∼25 mm2 and 10 μm wide features have been printed. (Some figures in this article are in colour only in the electronic version)

Waste tank cleanup manipulator modeling and control
Waste tank Cleanup is a current application area for robotics in the United States. As a result of tank access restrictions, (e.g., limited number and size of manholes), designs for several current waste Cleanup manipulator systems have long links with small cross-sections and variable lengths. In addition, as a result of anticipated payload capacity, these manipulator designs are hydraulically...
متن کاملDesign and Fabrication of an Electrostatically Actuated Parallel-Plate Mirror by 3D-Printer
In this paper, design and fabrication of an actuated parallel-plate mirror based on a 3D-printer is described. The mirror and electrode layers are fabricated separately and assembled thereafter. The alignment is performed by dowel pin-hole pairs fabricated on the respective layers. The electrodes are formed on the surface of the electrode layer by Au ion sputtering using a suitable mask, which ...
متن کاملModel-Based Control of Hydraulically Actuated Manipulators
Model-based controllers have successfully been applied to many electrically driven robotic manipulators to improve their tracking performance. The application to hydraulically actuated systems however is not straight forward, due to the nonlinear internal dynamics of the actuators. This paper presents the modelling of an experimental hydraulic robot arm and the implementation of a cascaded cont...
متن کاملLiquid transfer between two separating plates for micro-gravure-offset printing
Experimental investigations of the liquid transfer between two separating plates have been carried out, with the aim of increasing the ink transfer ratio in micro-gravure-offset printing. A sessile droplet is divided into two by moving one plate vertically with respect to a fixed plate. The surface contact angles of the sessile droplet on the two plates were of particular interest in this study...
