Publication number: 20170351175Abstract: A synthetic paper is manufactured with a method comprising the steps of: a) providing at least two types of pho to-polymerizable monomers, b) exposing the volume to a three-dimensional light pattern to induce a polymerization reaction, and c) removing uncured monomer to create an open microstructure. The volume comprises at least one monomer comprising at least two thiol groups and at least one monomer comprising at least two carbon-carbon double bonds, where the ratio (r1) between the number of thiol groups and the number of carbon-carbon double bonds fulfils one of: 0.5?r1?0.9 and 1.1?r1?2. One advantage is that off stoichiometry creates an edge effect giving better defined boundaries between exposed and unexposed parts in the volume and giving a possibility to create thinner micro pillars. Another advantage is that it is easy to bind molecules to the surface to obtain desired surface properties.Type: ApplicationFiled: January 18, 2016Publication date: December 7, 2017Inventors: Jonas Hansson, Hiroki Yasuga, Wouter Van Der Wijngaart, Tommy Haraldsson

Publication number: 20070090314Abstract: The present invention discloses a microvalve for providing pneumatic-flow regulation suitable for use in microsystem applications that are operable using highly efficient actuation means for flow obstruction while being space efficient in design in a manner that is suitable for cost effective bullsk microfabrication. In an embodiment of the invention, the microvalve comprises a first substrate layer, a second layer disposed over the first substrate layer cooperating with the first substrate layer to form a channel through which the flow traverses and defines a direction of the flow. An obstruction element or knife gate is micromachined into the second layer such that it is pivotably attached and actuated with a bimorph actuator to displace the gate along a plane that is substantially perpendicular to the direction of the flow in order to controllably regulate the flow.Type: ApplicationFiled: June 7, 2004Publication date: April 26, 2007Inventors: Wouter Van Der Wijngaart, Goran Stemme, Anthony Ridgeway
