MetaSub piezoelectric energy harvesting
Smart Structures and NDE for Industry 4.0, Smart Cities, and Energy Systems, 2020This paper introduces a creative metamaterial-based substrate (MetaSub) for piezoelectric energy harvesters. The MetaSub is a platform with a high flexibility in both longitudinal and transverse directions. The novel design of the MetaSub remarkably improves the productivity of strain-induced devices in structural health monitoring (SHM) applications ...

Energy harvesting with multilayer piezoelectric ceramics
2014 15th International Conference on Electronic Packaging Technology, 2014Energy harvesting from piezoelectric ceramic components can be achieved in three ways. These are impact induced, continues vibration induced, and decaying vibration induced. Defining the necessary characteristic of piezoelectric materials in ATILA provides the preliminary knowledge of expectation result of multilayer product under vibration condition ...

Piezoelectric fibers for energy harvesting.
The Journal of the Acoustical Society of America, 2010Most energy harvesting devices rely on traditional piezoelectric materials integrated in structures subjected to mechanical vibrations. A new kind of commercially available composite sensors consists of several PZT fibers embedded in a passive polymer matrix with interdigitated electrodes deposited on the polymer. The main advantage of these sensors is
