This technology uses a piezo-magneto-elastic device for substantial performance enhancement in broadband vibration energy harvesting. The prototype tested in our lab exhibits large-amplitude periodic (limit cycle) oscillations for excitations over a frequency range. The piezo-magneto-elastic generator results in a 200% increase in the open-circuit voltage amplitude (hence promising ...

Lead-free piezoelectric ceramics have been widely studied to find alternative for (Pb,Zr)TiO3 (PZT). Among the various possible candidates, (K,Na)NbO3 (KNN) based materials have gained considerable attention owing to their excellent piezoelectric properties and high Curie temperature. However, KNN based ceramics have shown significant drop of piezoelectric response as a ...

Four-bar magnet geometries for vibration energy harvesting are advantageous because they allow achieving a high transformation factor without the necessity of generating radial magnetic field. We have developed the technique to achieve near optimal amount of electrical damping and thus relatively high output power for a given base excitation from ...

We have been sucessful in synthesizing magneto-electric (ME) 3-2 nanocomposite thick films using aerosol-deposition (AD) that provide giant performance. Piezoelectric and magnetostrictive materials were simultaneously deposited on a platinized silicon substrate using AD method and a 13 micron-thick nanocomposite film was realized with repeatable nozzle scanning. Upon annealing, magnetostrictive ...

This invention aims to provide good mixing quality and/or smart blending for complex, time-dependent, viscous, non-Newtonian fluids using laminar flow (i.e. slow moving and/or small-scale flows). Traditionally, mixing is usually achieved through the generation of turbulence. However, for a range of industrial and research processes in which delicate molecules (such ...
