Working equations for piezoelectric actuators and sensors

M. S. Weinberg Journal of Microelectromechanical Systems, 1999

A new solution to the force, displacements, and charges developed in piezoelectric beams is derived. Differing from previous solutions, this development determines the neutral axis where the bending strains are zero and results in a closed form solution (without matrix inversion). With the closed form, simplifications become evident which increase understanding and facilitate calculations. These equations are than expanded to ...

The characteristics of nano-crystalline silicon (nc-Si) embedded in Si-based dielectric matrix have been investigated extensively.

  • Design and Fabrication of Flexible Piezoelectric Generators Based on ZnO Thin Films

    The piezoelectric transducer for vibration-energy harvesting is constructed of a piezoelectric layer, bottom electrode and a top electrode. In order to obtain an appropriate transducer for the low-frequency operating; environmentally-friendly and long-term, the flexible substrate, the piezoelectric layer, and the additional mass-loading have been investigated thoroughly. Firstly, flexible piezoelectric harvesters based on ZnO (Zinc Oxide) thin films for self-powering and broad bandwidth applications. The design and simulation of a piezoelectric cantilever plate was described by using commercial software ANSYS FEA (finite element analysis) to determine the optimum thickness of PET substrate, internal stress distribution, operation frequency and electric potential. A modified design of a flexible piezoelectric energy-harvesting system with a serial bimorph of ZnO piezoelectric thin film was presented to enhance significantly higher power generation. This high-output system was examined at 15 Hz. The maximum DC (direct current) voltage output voltage with loading was 3.18 V, and the maximum DC power remained at 2.89 ¿¿W/cm2. Secondly, this investigation fabricates double-sided piezoelectric transducers for harvesting vibration- power. The double-sided piezoelectric transducer is constructed by depositing piezoelectric thin films. The Ti (titanium) and Pt (platinum) layers were deposited using a dual-gun DC sputtering system between the piezoelectric thin film and the back side of the SUS304 substrate. The maximum open circuit voltage of the double-sided ZnO power transducer is approximately 18 V. After rectification and filtering through a 33 nF capacitor, a specific power output of 1.3 ¿¿W/cm2 is obtained from the double-sided ZnO transducer with a load resistance of 6 M?>

  • Introduction

    n applications, microsystems have to be self-powered; therefore, efficient energy scavenging is crucial. The self-powered microsystems are designed to avoid the replacement of energy cells and miniature sensing devices. Vibration-based energy harvesting is a process of capturing ambient kinetic energy and converting it into usable electricity. The growing demand of cell phone devices such as miniature wireless sensor networks, the recent advent of the extremely low power controlled circuit and MEMS devices make such renewable power sources very attractive. In addition, the energy harvesting process is practicable with environmental vibrations such as running machines and human body movement. However, the wide range of environmental energy keeps harvester low efficiency when deployed in a stochastic surrounding vibration.

  • Mechanical Energy Harvesting with Piezoelectric Nanostructures: Great Expectations for Autonomous Systems

    This chapter contains sections titled: * Introduction * Mechanical Energy Harvesting using MEMS * Mechanical Energy Harvesting using Piezoelectric Nanostructures * Further Improvements at the Nanoscale * Towards Completely Autonomous Systems: Multisource Approach * Conclusions and Future Prospects

  • Will Composite Nanomaterials Replace Piezoelectric Thin Films for Energy Transduction Applications?

    Semiconducting piezoelectric nanowires (NWs) show significant potential for application in electronic and electromechanical sensors and energy harvesters. In particular, these nanostructures can be used to build composite piezoelectric materials that could offer several advantages when integrated vertically. First, NWs of various lengths opens the possibility to fabricate composite layers thicker than standard thin films (<4 ¿¿m). Second, low¿¿¿temperature fabrication process make this technology compatible with CMOS devices and with different substrates, such as Si, polymers, plastics, metal foils, and even paper. Third, properties such as piezoelectricity, flexibility, and dielectric constant can be improved in NWs, thereby improving the performance of NW¿¿¿containing composite materials. Finally, FEM simulations show that composites can provide better performance compared to piezoelectric thin films of the same thickness, and that performance can be improved by operating in compression or flexion modes by the right choice of the dielectric matrix and NW density.
