Nanostructured ZnO has great potential for many practical applications, such as dye sensitized solar cells, piezo electric transducers, UV-light emitters, chemical and gas sensors and transparent conductive coating [9].
A piezo-electric transducer combining efficiency and compactness was selected as a secondary source.
Comparisons with experiment are performed in the time, frequency and joint-time frequency domain for both narrow band and broad band excitation of the piezo-electric transducer.
This paper describes a sensor for measuring the mass flux of aeolian sand transport based on a low-cost piezo-electric transducer.
In this work, an acoustic-to-electric transducer for application with a back-to-back standing wave thermoacoustic engine, based on a linearly-acting variable-reluctance generator is proposed, built and experimentally tested.
The objective lens was scanned along the axial (depth) dimension by a focusing mechanism, comprising a miniature linear guide and a piezo-electric transducer (PZT) actuator (TULA35, Piezoelectric Technology, South Korea; maximum speed = 27 mm/sec; maximum motion range = 10.6 mm) [ 23].
Since the grinding force was adjusted by the machine power, a piezo-electric transducer-based dynamometer (Kistler 7257B) was mounted under the working table to measure the normal force during grinding operations, as shown in Fig. 2.
Both conventional piezo-electric transducers and laser interferometers can be used to monitor the ultrasound.
Evans et al. (2010) functionalized and assembled BaTiO3 and CoFe2O4, having magnetoelectric properties shown in Figure 10 applicable for magnetic-electric transducers sensors, actuators, and memory devices.
The applied techniques were integrated optical fibres with distributed fibre Bragg grating sensors (FBGs), stereo-vision digital image correlation (DIC) without the use of a speckle pattern, optical fibre sensors for acoustic emission sensing (AE-FOS), piezo-electric transducers for acoustic emission sensing (AE-PZT) and LVDTs.
