Abstract: An inkjet head chip identification circuit is disclosed and includes an identification circuit matching with a printer so that the printer provides an inkjet head chip with required information according to the matching result. The identification circuit includes plural memory units. The memory units arranged in an array structure and include a first transistor, a third transistor, a fuse or a combination thereof. By burning the elements in the array structure or not, a data signal of each memory unit is read. The first transistor is a MOSFET-Anti-Fuse. The third transistor is an EPROM. The first transistor, the third transistor and the fuse are formed on the same inkjet head chip.

Abstract: The present disclosure provides a control method of a fluid device. The control method includes the steps of (a) providing the fluid device, which includes a plurality of flow guiding units manufactured by a micro-electro-mechanical-system process; (b) dividing the flow guiding units into a plurality of groups, which are electrically connected to and controlled by a control module; and (c) generating a driving signal by the control module for a corresponding one of the groups, wherein the control module generates a high level signal to a specific one of the groups, so that the flow guiding units of the specific one of the groups are driven to transport fluid, and thereby controlling the fluid device to discharge a specific amount of fluid.

Abstract: An electronic cigarette includes a power supply device, an atomizer, a liquid storage structure, a fluid transportation device, a sensing unit, a casing and a mouthpiece. The atomizer includes an electric heater and a liquid conduit. The liquid storage structure includes a liquid container for storing a cigarette liquid. The fluid transportation device is in communication with the liquid container and the liquid conduit. The cigarette liquid is transferred to the liquid conduit through the fluid transportation device. The sensing unit includes an airflow sensor and an air pressure sensor for adjusting the speeds of atomizing the cigarette liquid and providing the cigarette liquid. After an airflow is fed into an entrance of the casing, the airflow passes through an airflow chamber and the sensing unit along an airflow path. The mouthpiece seals an end of the casing and in communication with the airflow path.

Abstract: A micro-electromechanical fluid control device includes at least one flow guiding unit. The at least one flow guiding unit includes an inlet plate, a substrate, a resonance membrane, an actuating membrane and an outlet plate sequentially stacked. A first chamber is defined between the resonance membrane and the actuating membrane and a second chamber is defined between the actuating membrane and the outlet plate. While the piezoelectric membrane of the flow guiding unit drives the actuating membrane, a fluid is inhaled into the convergence chamber via the inlet of the inlet plate, transported into the first chamber via the central aperture of the resonance membrane, transported into the second chamber via a vacant space of the actuating membrane, and discharged out from the outlet of the outlet plate, so as to control the fluid to flow.
