    Abstract: A fluid system includes a fluid active region, a fluid channel, a convergence chamber and plural valves. The fluid active region includes one or plural fluid-guiding units. Each fluid-guiding unit includes an inlet plate, a substrate, a resonance plate, an actuating plate, a piezoelectric element and an outlet plate, which are stacked sequentially. The piezoelectric element is attached on the actuating plate. When the piezoelectric element drives a bending resonance of the actuating plate, the fluid is transported into the fluid-guiding units and pressurized to be discharged out. The fluid channel includes plural branch channels. The fluid discharged from the fluid active region is split by the branch channels. The convergence chamber is in communication with the fluid channel. The valves are disposed in the branch channels. The fluid is transported through the branch channels according to the open/closed states of the valves.

    Abstract: A fluid control device includes a piezoelectric actuator, a housing and a glue body. The piezoelectric actuator includes a suspension plate, an outer frame, a bracket and a piezoelectric element. The housing includes an outlet plate and a base. The outlet plate accommodates the piezoelectric actuator and the base includes an inlet plate and a resonance plate. The glue body is arranged between the outer frame and the resonance plate to maintain a gap formed therebetween. The suspension plate is made of a material having a linear expansion coefficient less than a linear expansion coefficient of the piezoelectric element. The suspension plate has a specified hardness to maintain a curved shape after being heated, and the linear expansion coefficient of the suspension plate is different from a linear expansion coefficient of the resonance plate, so that an effective deformation displacement between the suspension plate and the resonance plate is obtained.

    Abstract: An electronic device includes a casing, a speaker enclosure and an actuating and sensing module. The casing has an opening. The speaker enclosure is disposed within the casing to enclose a speaker. The speaker enclosure is in communication with the opening of the casing. The actuating and sensing module is disposed within the speaker enclosure. The actuating and sensing module comprises a fluid transportation device and a sensor. The fluid transportation device is driven to transport a fluid from outside the casing into the speaker enclosure through the opening of the casing to make the fluid sensed by the sensor.

    Abstract: A three-dimensional integrated circuit cooling system is provided for removing heat from a three-dimensional integrated circuit. Plural fluid microchannels are formed among plural middle chip layers and a main chip layer of the three-dimensional integrated circuit. The three-dimensional integrated circuit cooling system comprises a base and a fluid pump. The base has an introduction opening, a discharge opening and a fluid passage. The fluid pump is fixed on the base and seals the edge of the introduction opening. When the fluid pump is enabled, an ambient fluid is driven by the fluid pump, introduced into the fluid passage through the introduction. opening, and discharged through the discharge opening. The discharged fluid passes along every fluid microchannel of the three-dimensional integrated circuit as flowing through the plural middle chip layers and the main chip layer so as to perforin heat exchange therewith.

    IPC: H01L41/04

    Abstract: A driving system includes a voltage conversion module, a switching module, a detecting module, a voltage dividing module and a microcontroller. The voltage conversion module converts a first DC voltage into a second DC voltage. The switching module converts the second DC voltage into an AC voltage so as to drive a piezoelectric actuator of a piezoelectric pump. The detecting module includes a feedback circuit and a gas pressure sensor, wherein the feedback circuit detects an electric power reference value of the switching module, and the gas pressure sensor detects the gas pressure value of the piezoelectric pump. The microcontroller acquires a working frequency according to the electric power reference value so as to operate the piezoelectric actuator at the working frequency. The microcontroller controls the voltage conversion module to adjust the output voltage. Consequently, a gas pressure in the piezoelectric pump is correspondingly adjusted.

    IPC: F04B43/04

    Abstract: A fluid control device includes a piezoelectric actuator and a deformable substrate. The piezoelectric actuator includes a piezoelectric element and a vibration plate. The piezoelectric element is attached on a first surface of the vibration plate and is subjected to deformation in response to an applied voltage. The vibration plate is subjected to a curvy vibration in response to the deformation of the piezoelectric element. A bulge is formed on a second surface of the vibration plate. The deformable substrate includes a flexible plate and a communication plate stacked on each other. A synchronously-deformed structure is defined by the flexible plate and the communication plate. The deformable substrate is bent in the direction away from the vibration plate. There is a specified depth maintained between the flexible plate and the bulge of the vibration plate. The flexible plate includes a movable part corresponding to the bulge of vibration plate.
