Abstract: An actuation unit for a multi valve device, the multi valve device comprising a fluidic unit comprising at least one fluid channel and a plurality of valves, wherein the valves selectively block or open the fluid channel. The actuation unit comprises a housing and at least one actuator module. The housing is configured to receive a plurality of actuator modules. The at least one actuator module is received within the housing. The actuator module comprises at least one actuator made of a smart material and at least one valve actuation member. The actuator is configured to move at least one valve actuation member such that at least one of the valves selectively blocks or opens the fluid channel. The actuation unit is connectable to the fluidic unit. Further, a multi valve device and a fluid handling device are proposed.

Abstract: An inventive actuator assembly has a substrate having a through hole. A circuit path is mounted on a side of the substrate and has a support surface that defines a circuit path through hole. An actuator made at least partially of a shape memory material is included and has first and second ends. The actuator has a through hole at least at the first end. A fastener extends through the actuator through hole, the circuit path through hole and the substrate through hole to permanently fix the substrate, the actuator and the circuit path at the first end of the actuator. The actuator may have through holes on both ends, such that the substrate includes a second substrate through hole and a second circuit path is provided that defines a second circuit path through hole. A second fastener fixes together the second end, the second circuit path and the substrate.

Abstract: A valve for switching of media, such as liquids or gases, is opened, closed or put into an intermediate state by at least one actuator produced from a shape memory alloy. The at least one actuator, as a function of whether electricity is applied to it, acts on at least one valve ball or a valve plunger accommodated in a core element, so that the through-flow of a medium through a fluid part below the core element, with a media-tight membrane interposed between, is opened, interrupted or partially opened in regulated or controlled manner. The core element is produced from a mechanically rigid and thermally well-conductive material, has electrical conductor tracks for electrical connection of the actuator to a supply of electricity on the top side, as well as multiple threaded through-holes for underside connection with the fluid part and the membrane and/or for top-side connection with the actuator.

Abstract: A thermoelectric system includes a plurality of thermocouples that are each formed of two thermocouple limbs that include different thermoelectrically active materials. The thermocouple limbs are connected electrically in series and thermally in parallel. The thermodynamic system also includes a flexible and electrically insulating layer formed of a matrix having n rows of thermocouple limbs. The thermocouple limbs form columns having approximately equal widths. Each pair of adjacent thermocouple limbs has a contact region located on a straight fold line above one another in the column direction. The matrix is wound parallel to the rows on top of one another to form a flat strip. The matrix is then folded along the fold lines in the manner of a concertina with elevations and depressions equidistant to one another.
