Shape memory alloy (SMA) thin films formed by sputter deposition have attracted considerable attention in the last decade. Current intensive research demonstrated that thin films' unique fine microstructure is responsible for superior shape memory characteristics in films, compared to that of bulk materials. Simultaneously, much effort has been taken in the development and fabrication of microd...

Abstract Aiming at the demand for passive sonar systems medium and low-frequency detection, low cost, small working platform sensor, a three-axis pressure piezoelectric accelerometer based on ceramic fiber is designed. Firstly, acoustic vibration pick-up principle extended Hamilton, action mode of analyzed theoretically to determine structure size. The with special mass designed by using axiall...

In order to realize the collection of micro or small vibration energy, a micro-power generator based on two piezoelectric Macro Fiber Composite (MFC) films is proposed. The consists double MFCs type vibrator and displacement amplifying mechanism, which can achieve output high energy density. design process this kind presented. Based LabVIEW platform NI Data Acquisition (DAQ) card, voltage acqui...

The rapid development of technology causes humans to provide a large amount energy, especially electrical energy. One the new renewable energy sources that is still under piezoelectric-based harvester. Piezoelectric itself material has an electric polarizing effect occurs in certain materials when given mechanical stress. potential difference measured across piezoelectric proportional applied p...

BACKGROUND Intracytoplasmic sperm injection (ICSI) requires long training and has low success rates, primarily due to poor control over the injection force. Making force feedback available to the operator will improve the success rate of the injection task. A macro-micro-teleoperation system bridges the gap between the task performed at the micro-level and the macroscopic movements of the opera...
