摘要： A fluidic system having a first volume, a second volume and a membrane geometrically separating the two volumes, which has an open-pore microstructure for the passage of a first medium and a second medium. There is a contact angle (Θ) between the interface of the media and the pore surface. A first electrical field 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 and is more heavily wetted by the second medium such that a first contact angle Θ1>90° is formed between the pore surface and the interface. The first medium and the second medium 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 Θ2

摘要： A valve unit and an apparatus having the same include a plug which includes a phase change material in a solid state at a room temperature and a plurality of fine heat-dissipating particles dispersed in the phase change material. The fine heat-dissipating particles dispersed in the phase change material dissipate heat by absorbing an electromagnetic wave energy generated by electromagnetic wave radiation from the outside and block fluid flow in a path formed by a channel. As an external energy source irradiates an electromagnetic wave on the plug, the plurality of fine heat-dissipating particles dissipate heat and the phase change material becomes molten, thus opening the path to allow the fluid to flow.

摘要： A micro actuator system includes a micro actuator and a light beam generator. The micro actuator includes a substrate, a cantilever beam, and a carbon nano-tube layer. The cantilever beam has a connection portion connected to the substrate, and the carbon nano-tube layer is disposed on the cantilever beam in a spray deposition technique. When the light beam generator generates a light beam for irradiating the carbon nano-tube layer on the connection portion of the cantilever beam, the carbon nano-tube layer drives the cantilever beam to be deformed towards a first direction.
