the output of a piezoelectric nanogenerator based on zno nanowire is largely affected by the shape of nanowire. in order to obtain mechanically stable nanogenerator with high performance, the investigation of mechanical and electrical characteristics related to the nanowires and materials used in nanogenerators are of great interest and significance. this paper presents the various behavior of ...

Piezoelectric nanogenerators (PNGs) are capable of converting energy from various mechanical sources into electric energy and have many attractive features such as continuous operation, replenishment and low cost. However, many researchers still have studied novel material synthesis and interfacial controls to improve the power production from PNGs. In this study, we report the energy conversio...

Condition assessment of cables has gained considerable attention for the bridge safety. A magnetic flux leakage and magnetostrictive guided wave hybrid transducer is provided to inspect bridge cables. The similarities and differences between the two methods are investigated. The hybrid transducer for bridge cables consists of an aluminum framework, climbing modules, embedded magnetizers and a r...

Development of Apple Workgroup Cluster and Parallel Computing for Phase Field Model of Magnetic Materials. (May 2009) Yongxin Huang, B.S., University of Science and Technology of China Chair of Advisory Committee: Dr. Yongmei Jin Micromagnetic modeling numerically solves magnetization evolution equation to process magnetic domain analysis, which helps to understand the macroscopic magnetic prop...

This paper addresses the modeling of strains and forces generated by magnetostrictive transducers in response to applied magnetic elds. The magnetostrictive eeect is modeled by considering both the rotation of magnetic moments in response to the eld and the elastic vibrations in the transducer. The former is modeled with the Jiles-Atherton model of ferromagnetic hysteresis in combination with a...

Magnetostrictive transducers are becoming increasingly prevalent in industrial applications including high speed milling and hybrid motor design due to their broadband, large force capabilities. To achieve the level of performance required by such applications, however, these transducers must operate in nonlinear and hysteretic regimes. To accommodate this nonlinear behavior, models and control...
