    Abstract: A piezoelectric energy hunting device and a voltage signal application system thereof are disclosed. The piezoelectric energy hunting device includes a plurality of curved piezoelectric elements, a plurality of rigid foams, and a flexible foam structure. The plurality of curved piezoelectric elements are arranged side by side with one another, wherein each curved piezoelectric element is attached to one of the rigid foams. The flexible foam structure includes a top foam and a bottom foam covering the outer surface of the plurality of curved piezoelectric elements and the plurality of rigid foams; when the flexible foam structure is compressed, the plurality of curved piezoelectric elements are simultaneously deformed, thereby generating a voltage signal. When the flexible foam structure is not compressed, the flexible foam structure and the plurality of rigid foams provide an elastic force to restore the plurality of curved piezoelectric elements.

    Abstract: A piezoelectric system for ultrasonic thermotherapy and electrotherapy comprises a first piezoelectric element, a proof mass, a second piezoelectric element and an output unit. The proof mass is disposed between the first piezoelectric element and the second piezoelectric element. The first piezoelectric element is powered by a power source to generate oscillation, which is transferred by the proof mass to the second piezoelectric element so as to cause the second piezoelectric element to move and generate power. The output unit comprises a connecting surface and a tip surface. The output unit is electronically connected with the second piezoelectric element, wherein the connecting surface is connected with the first piezoelectric element and the tip surface is formed in a tapered shape. The oscillation from the first piezoelectric element and the power generated by the second piezoelectric element are output through the tip surface.

    Abstract: A linear piezoelectric motor and a slider drive system thereof are disclosed. The linear piezoelectric motor includes a piezoelectric ceramic element and a base structure. The piezoelectric ceramic element includes a first region, a second region and an interval region located between the first and the second region, wherein the first and the second region may be formed by a first and a second power signal supplied by a power supply to form a first and a second standing wave, respectively. The interval region is a quarter wavelengths. The first and the second standing wave have a phase difference so as to form a traveling wave. The base structure disposes the piezoelectric ceramic element and has a pectinate structure to increase the amplitude of the first and the second standing wave, thereby enabling the piezoelectric motor to be driven.

    Abstract: A triaxial piezoelectric sensor includes a PVDF layer, a first line layer, and a second line layer. The PVDF layer has multiple first electrodes and multiple second electrodes. Each first electrodes corresponds to each second electrodes for forming directions of polarization along the X-Y-Z axes. The first line layer has multiple first electrical connection portions and multiple first signal lines. Each first electrical connection portions corresponds to each first electrodes. The second line layer has multiple second electrical connection portions and multiple second signal lines. Each second electrical connection portions corresponds to each second electrodes. The PVDF layer is sandwiched between the first line layer and the second line layer. When an external force is applied to the PVDF layer, the first signal lines and the second signal lines transmit electrical signals according to the deformation of the PVDF layer.
