Sensors and Actuators A: Physical, 2002
Abstract A design concept for multilayer piezoelectric microactuator using piezoelectric coefficient d 31 was particularly stressed. Accordingly, two kinds of novel piezoelectric multilayer microactuators, called a split-morph and an annular split-morph, have been proposed and discussed for the dual stage actuation systems in high track density ...

Low frequency PVDF piezoelectric energy harvester with combined d31 and d33 operating modes
The 8th Annual IEEE International Conference on Nano/Micro Engineered and Molecular Systems, 2013This paper reports the design, test and application of a novel low frequency piezoelectric energy harvester. To achieve high output voltage at low frequency, both d31 and d33 modes of polyvinylidene fluoride (PVDF) are utilized in this device. Output voltage of the device are tested under different frequencies and accelerations.

Ferroelectrics, 1986
Values are reported for the piezoelectric coefficients d31 and d3h, of highly oriented one-way drawn polyvinylidene fluoride. Samples were compared with high Form I content following two preparation procedures, one giving material of low Young's modulus by drawing to a conventional draw ratio and the other of high Young's modulus by drawing to a very ...

Current Applied Physics, 2011
Abstract We report fabrication by a traditional ceramics process of a dome-like actuator composed of two PZT piezoelectric ceramics, one doped with donors (La 3+ and Nb 5+ ) and the other with acceptors (Fe 3+ and Ni 2+ ). The results show that at 120 °C, the resistivity of PZT doped with La 3+ and Nb 5+ is three orders of magnitude more than ...

Road traffic noise abatement - the case of State Road D31
2011Traffic noise and its influence on the environment is an important factor to be considered when it comes to developing, upgrading, and maintaining national road networks. This paper describes the design process of the road traffic noise protection barriers on the planned section of state road D31, a road that will help to connect the fast growing city ...
