Abstract: For manufacturing an optical microelectromechanical device, a first wafer of semiconductor material having a first surface and a second surface is machined to form a suspended mirror structure, a fixed structure surrounding the suspended mirror structure, elastic supporting elements which extend between the fixed structure and the suspended mirror structure, and an actuation structure coupled to the suspended mirror structure. A second wafer is machined separately to form a chamber delimited by a bottom wall having a through opening. The second wafer is bonded to the first surface of the first wafer in such a way that the chamber overlies the actuation structure and the through opening is aligned to the suspended mirror structure. Furthermore, a third wafer is bonded to the second surface of the first wafer to form a composite wafer device. The composite wafer device is then diced to form an optical microelectromechanical device.

Abstract: A manufacturing method of miniature fluid actuator is disclosed and includes the following steps. A flow-channel main body manufactured by a CMOS process is provided, and an actuating unit is formed by a deposition process, a photolithography process and an etching process. Then, at least one flow channel is formed by etching, and a vibration layer and a central through hole are formed by a photolithography process and an etching process. After that, an orifice layer is provided to form at least one outflow opening by an etching process, and then a chamber is formed by rolling a dry film material on the orifice layer. Finally, the orifice layer and the flow-channel main body are flip-chip aligned and hot-pressed, and then the miniature fluid actuator is obtained by a flip-chip alignment process and a hot pressing process.

Abstract: A MEMS temperature sensor including a clamped-clamped microbeam having a drive electrode on one side configured for applying an AC current, and a sense electrode diagonally situated on the other side, a first anchor at one end and a second anchor at the other end of the microbeam. The first anchor receive a DC bias currents, which heats the microbeam to an operating temperature. The sense electrode is configured to capacitively sense oscillations in the microbeam due to an applied AC current. The MEMS temperature sensor has a three wafer construction in which the components are formed. The device is encapsulated by aluminum, and metal wires connect the first and second anchor, the drive electrode and the sense electrode to side electrode pads outside of the encapsulation. The MEMS temperature sensor has a linear operating region of 30-60 degrees Celsius.

Abstract: The invention relates to a component (4) of a biosensor, comprising at least one first device (6) for receiving a sample liquid, wherein the device (6) is connected via a distributor channel (7) to further receiving devices (8 to 11), into each of which a feed channel (71, 72, 73, 74) branching off from the distributor channel (7) opens, and the feed channels (71, 72, 73, 74) are arranged in succession in flow direction (S) of the sample liquid passed on through the distributor channel (7). In accordance with the invention, it is envisaged that, in the distributor channel (7), in each case between two immediately successive feed channels (71, 72; 72, 73; 73, 74) in flow direction (S), at least one region (K) for at least temporary slowing or stoppage of the capillary flow of the sample liquid has been inserted. It is thus possible to control the capillary flow of the sample liquid such that always only one receiving device (8, 9, 10, 11) is filled with the volume flow of sample liquid available before the next is filled, and effectively simultaneous filling of the receiving devices (8, 9, 10, 11) is prevented. This leads to rapid and complete filling of the respective receiving device (8, 9, 10, 11). Additionally presented is a process with which the regions (K) can be inserted into the distributor channel (7) in a simple manner.

Abstract: The disclosure describes a soft-matter electronic device having micron-scale features, and methods to fabricate the electronic device. In some embodiments, the device comprises an elastomer mold having microchannels, which are filled with an eutectic alloy to create an electrically conductive element. The microchannels are sealed with a polymer to prevent the alloy from escaping the microchannels. In some embodiments, the alloy is drawn into the microchannels using a micro-transfer printing technique. Additionally, the molds can be created using soft-lithography or other fabrication techniques. The method described herein allows creation of micron-scale circuit features with a line width and spacing that is an order-of-magnitude smaller than those previously demonstrated.
