摘要： A valveless micro impedance pump including a bottom layer, a middle layer, a top layer and a piezoelectric element. The middle layer and the top layer are sealed to form the water inlets/outlets, flow way, upper and lower vibration membranes and boss of the micropump. The piezoelectric element is fixed on the boss and the fixing seat. By means of the electric field effect, the upper and lower vibration membranes are pushed by the piezoelectric element through the boss. The medium within the flow way is squeezed to flow toward the water inlets/outlets on two sides. The upper and lower vibration membranes have different structures. Also, the hardness of the fixing seat is different from the hardness of the bottom layer. This leads to difference in impedance. Therefore, the wave of the medium can be transmitted.

摘要： A fluid transportation device includes a valve seat, a valve cap, a valve membrane, multiple buffer chambers, a vibration film and an actuator. The valve membrane is arranged between the valve seat and the valve cap, and includes several hollow-types valve switches, which includes at least a first valve switch and a second valve switch. The multiple buffer chambers include a first buffer chamber between the valve membrane and the valve cap and a second buffer chamber between the valve membrane and the valve seat. The vibration film is separated from the valve cap when the fluid transportation device is in a non-actuation status, thereby defining a pressure cavity. The actuator is connected to the vibration film. When the actuator is driven to be subject to deformation, the vibration film connected to the actuator is transmitted to render a volume change of the pressure cavity and result in a pressure difference for moving the fluid.

摘要： An inkjet head manufacturing method includes the following steps. Firstly, a multilayered structure with a plurality of microstructure layers is provided. The alignment check holes of the microstructure layers are concentric and have different diameters. Then, the microstructure layers are stacked together and the microstructure layers are aligned with each other according to the concentric and different-diameter alignment check holes, wherein a dry film layer is sandwiched between every two adjacent microstructure layers. The preset slots of the microstructure layers are collectively defined as inlet flow channels, ink chambers, pressure cavities and outlet flow channels. Then, the multilayered structure is assembled and positioned through the dry film layers by a thermal compression process. Then, a cutting knife is used to linearly cut the actuator plate over a spacer between every two adjacent pressure cavities and along a path parallel with rims of the pressure cavities.
