Abstract: A piezoelectric actuator for a miniature fluid transportation device is provided and includes a piezoelectric actuating plate and a piezoelectric element. The piezoelectric actuating plate includes a suspension plate, an outer frame, and brackets. The suspension plate has a first thickness. The outer frame is arranged around the suspension plate and has a third thickness. Each of the brackets is connected between the suspension plate and the outer frame and has a fourth thickness. The third thickness is larger than the first thickness, and the first thickness is larger than the fourth thickness. The suspension plate, the outer frame and the brackets are constructed to form different stepped structures to minimize the thickness of the brackets, enhance the elasticity of the brackets. Thus, displacement of the suspension plate in the vertical direction is enhanced and the transportation efficiency of the miniature fluid transportation device is intensified.

Abstract: A pair of glasses with a wearing cushion device comprises a main body, an inflatable cushion system, an air pump, a switch element, a control unit and an air channel. The inflatable cushion system comprises two supporting cushions and two buffer cushions. When the switch element is turned on, the switch element issues an enabling signal to the control unit and the control unit enables the air pump in response to the enabling signal. When the air pump is enabled, an ambient gas is transferred to the two supporting cushions and the two buffer cushions through the air channel. The two supporting cushions and the two buffer cushions are inflated with the gas and expanded, so as to fit closely on the ears of the user by the two buffer cushions, and fit closely on the bridge of the nose of the user by the supporting cushions.

Abstract: A shoe automatic inflatable cushion system is applied to a shoe which includes a shoe body and a bottom part connected therewith. When a weight sensor disposed on the bottom part detects a load, a control module receives an enabling signal and accordingly drives an air pump to operate, so that an inflatable cushion disposed in the shoe body is inflated and expanded. When an air pressure sensor detects the pressure inside the inflatable cushion higher than a specified threshold interval, the air pressure sensor sends a disabling signal to the control module, and the control module receives a disabling signal and accordingly stops operation of the air pump.

Abstract: A miniature fluid control device includes a gas inlet plate, a resonance plate and a piezoelectric actuator. The gas inlet plate includes at least one inlet, at least one convergence channel and a central cavity. A convergence chamber is defined by the central cavity. The resonance plate has a central aperture. The piezoelectric actuator includes a suspension plate, an outer frame and a piezoelectric ceramic plate. A gap is formed between the resonance plate and the piezoelectric actuator to define a first chamber. When the piezoelectric actuator is driven and after the gas is fed into the miniature fluid control device through the inlet of the gas inlet plate, the gas is sequentially converged to the central cavity through the convergence channel, transferred through the central aperture of the resonance plate, introduced into the first chamber, transferred downwardly through the piezoelectric actuator, and exited from the miniature fluid control device.

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. The piezoelectric element 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, which are stacked on each other. Consequently, a synchronously-deformed structure is defined by the flexible plate and the communication plate collaboratively, and 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 the vibration plate.

The piezoelectric actuator includes a piezoelectric element and a vibration plate. The deformable substrate includes a flexible plate and a communication plate. A bulge is formed on the vibration plate. The flexible plate includes a movable part. Next, the flexible plate and the communication plate are stacked and coupled, and a preformed synchronous deformation process is implemented by applying at least one external force to outer portion of the deformable substrate to form a preformed synchronously-deformed structure. Then, the housing, the piezoelectric actuator and the deformable substrate are sequentially stacked and coupled. The preformed synchronously-deformed structure is aligned with the bulge of the vibration plate. Consequently, a specified depth is defined between the movable part of the flexible plate and the bulge of the vibration plate.
