    Abstract: A micropump for pumping liquid from an entry channel to an exit channel is disclosed. The micropump is formed in a semiconductor substrate sealed by two glass substrates. The micropump includes first and second chambers and flow channel means coupled between the two chambers. The micropump also includes a valve coupled between the entry channel and the first chamber. The valve includes a flexible valve membrane positioned closer to a second side of the semiconductor substrate than to its first side for causing the valve to be or not to be in contact with the second side of the semiconductor substrate for closing or opening the valve on the glass substrate. Additionally, the micropump includes a diaphragm forming part of a flexible wall of the second chamber and positioned closer to the second side of the semiconductor substrate than to its first side. The diaphragm is responsive to external pressure for causing liquid to be pumped from the entry channel to the exit channel. Thus, the height of the valve is reduced, preventing deformation due to strength such as its own weight and may impact due to a dropping. As a result, the valve sealing is improve on the glass substrate. Therefore, the micropump can accurately discharge a small quantity of liquid.

    Abstract: A flexible patch pump for controllable accurate subcutaneous delivery of one or more medicaments to a patient includes a laminated layered structure. The pump may have a rigid reservoir layer including a number of rigid reservoirs disposed in a flexible material; a flexible microfluidic layer including a compliant membrane for sealing the rigid reservoirs, a network of microfluidic channels connecting the rigid reservoirs, and a number of inlet and/or outlet valves corresponding to the rigid reservoirs; and a flexible-rigid electronic circuit layer including a number of individually-addressable actuators. In operation, the rigid reservoirs may contain medicament that is dispensed in precise volumes at appropriate times due, for to example, to a pressure change in an addressed reservoir caused by displacement of the compliant membrane or other actuation element.

    Abstract: A micro-electromechanical (MEM) synthetic jet actuator includes a semiconductor substrate having a cavity extending therethrough, such that a first opening is formed in a first surface of the semiconductor substrate and such that a second opening is formed in a second surface of the semiconductor substrate. A first flexible membrane is formed on at least a portion of the front surface of the semiconductor substrate and extends over the first opening. The first flexible membrane also includes an orifice formed therein aligned with the first opening. The MEM synthetic jet actuator also includes a second flexible membrane that is formed on at least a portion of the second surface of the semiconductor substrate and that extends over the second opening, and a pair of actuator elements coupled to the flexible membranes and aligned with the cavity to selectively cause displacement of the first and second flexible membranes.
