    Abstract: A micro fluid actuator includes an orifice layer, a flow channel layer, a substrate, a chamber layer, a vibration layer, a lower electrode layer, a piezoelectric actuation layer and an upper electrode layer, which are stacked sequentially. An outflow aperture, a plurality of first inflow apertures and a second inflow aperture are formed in the substrate by an etching process. A storage chamber is formed in the chamber layer by the etching process. An outflow opening and an inflow opening are formed in the orifice layer by the etching process. An outflow channel, an inflow channel and a plurality of columnar structures are formed in the flow channel layer by a lithography process. By providing driving power which have different phases to the upper electrode layer and the lower electrode layer, the vibration layer is driven to displace in a reciprocating manner, so as to achieve fluid transportation.

    Abstract: A micro fluid actuator includes a first substrate, a chamber layer, a vibration layer, a first metal layer, a piezoelectric actuation layer, a second metal layer, a second substrate, an inlet layer, a resonance layer and an aperture array plate. The first substrate includes a plurality of first outflow apertures and a plurality of second outflow apertures. The chamber layer includes a storage chamber. The second metal layer includes an upper electrode pad and a lower electrode pad. While driving power having different phase charges is provided to the upper electrode pad and the lower electrode pad to drive and control the vibration layer to displace in a reciprocating manner, the fluid is inhaled from the exterior through the inlet layer, converged to the storage chamber, compressed and pushes out the aperture array plate, and then is discharged out from the micro fluid actuator to achieve fluid transportation.
