    Abstract: A fluidic device comprising a housing having an inlet (10) and an outlet (12) defining a fluid flow path (14) therebetween. A channel (16) is provided within the housing, which channel (16) is filled with a material (18), such as wax, which supports a reversible, electromagnetic energy activated change in plasticity and/or deformability. The channel (16) filled with material is covered (or enclosed) by a resiliently flexible membrane (20). A port (22) is provided in the housing for the application of pressure or vacuum to the material (18) in the channel (16). A valve seat (24) is provided between the inlet (10) and the outlet. When no electromagnetic energy is applied to the wax (18), it is in a substantially solid state and remains stationary within the channel (16). In use, to open the valve, the wax is melted by the application of electromagnetic energy thereto, and a vacuum is applied to the port (22), such that the portion of the membrane (20) adjacent the valve seat (24) is pulled down, away from the valve seat (24) as the molten wax is drawn back by the vacuum, thereby opening the fluid flow path (14) between the inlet (10) and the outlet (12). With the vacuum still being applied to the port (22), the wax is allowed (or caused) to cool, and the wax (18) solidifies, locking the valve in the open position. In order to close the valve, pressure is applied to the port (22) and the wax (18) is melted by the application of electromagnetic energy thereto. The pressure applied via port (22) pushes the wax forward along the channel (16) toward the fluid flow path (14). The build-up of pressure causes the portion of the membrane (20) adjacent the valve seat (24) to be pushed upwards toward the valve seat (24), thereby blocking the fluid flow path (14) and closing the valve. With pressure being applied to the port (22), the wax (18) is allowed (or caused) to cool, such that it solidifies, locking the valve in the closed position.

    Abstract: The invention relates to a fluidic system (52) having a first volume (V1), a second volume (V2) and a membrane (54) geometrically separating the two volumes, which has an open-pore microstructure for the passage of a first medium (M1) and a second medium (M2). There is a contact angle (Theta1) between the interface of the media and the pore surface. A first electrical field (U1) in the region of the membrane and a first electromagnetic radiation and a first heating of the membrane define a first state (Z1), in which the membrane is not wetted or is less wetted by the first medium (M1) and is more heavily wetted by the second medium (M2) such that a first contact angle Theta1 > 90° is formed between the pore surface and the interface. The first medium (M1) and the second medium (M2) and the pore surface have a surface energy of which at least one surface energy can be reversibly changed in such a way that a second contact angle Theta2
