A droplet delivery device includes a housing with a mouthpiece port or outlet from a nasal device for releasing fluid droplets, a fluid reservoir, and an ejector bracket having a membrane positioned between a mesh with a plurality of openings and a vibrating member that is coupled to an electronic transducer, such as an ultrasonic transducer. The transducer vibrates the vibrating member which causes the membrane to push fluid supplied by the reservoir through the mesh to generate droplets in an ejected stream released through the outlet.

A lens actuating device is applicable in a lens module. The lens module has at least a housing and a lens support in the space formed by the housing. The lens actuating device has at least a base disposed in the housing, a piezoelectric element disposed on the base for generating kinetic energy, a clamping component disposed on the piezoelectric element and a linkage element coupled to the lens support and clamped in the clamping component. The clamping component makes a corresponding motion upon receiving a kinetic energy created by the piezoelectric element, which allows a stick-slip friction to be generated in the clamping component to actuate the lens, thereby achieving optical zooming or focusing and avoiding the shortcomings of the prior art using for example a voice coil motor or a stepping motor.

A multi-layer piezoelectric component includes a plurality of piezoelectric layers, a first inner electrode sheet, a second inner electrode sheet, a first outer electrode, and a second outer electrode. The piezoelectric layers are wound around an axis to form a laminar roll having first and second end faces transverse to the axis. The piezoelectric layers include at least one first layer and at least one second layer. Each of the first and second layers has opposite first and second edges respectively at the first and second end faces, and opposite inner and outer circumferential surfaces. The first and second inner electrode sheets respectively overlie the inner circumferential surfaces of the first and second layers. The first and second outer electrodes are respectively and electrically connected to the first and second inner electrode sheets.

A piezoelectric transducer module includes first and second transducer units, each of which includes a conductive substrate portion that extends in a first direction and that has first and second surfaces opposite to each other in a second direction transverse to the first direction. At least one of the first and second surfaces has a piezoelectrically active coating coated thereon. The first and second transducer units are spaced apart from each other in the second direction. A connecting unit extends in the second direction and has opposite ends connected to the substrate portions of the first and second transducer units, respectively. The substrate portions of the first and second transducer units and the connecting unit are formed from a unitary conductive plate that is folded at junctions of the connecting unit and the substrate portions of the first and second transducer units.
