This paper presents the characterization of an energy harvester using a piezoelectric diaphragm as the vibration energy conversion microstructure. The diaphragm containing the spiral electrode operates in the d33 mode. The energy harvesting performance of the diaphragm was characterized. The optimal resistance load and the working frequency were characterized. The resonance tuning and the energy harvesting...
Harbor seals are known to track the hydrodynamic trails of their prey with only their whiskers. The geometry of their whiskers has been found to reduce vortex induced vibration (VIV). In this study, we develop an artificial whiskerlike sensor to evaluate the sensitivity and effectiveness of the seal whisker-like sensor configuration for underwater detection. These whisker-like sensors are towed downstream...
In this study we investigate two phenomena in the vibration of piezoelectric circular microdiaphragm (PCM) sensors, the non-degenerated vibration modes and increase of mass sensitivity with using higher modes. The investigated parameters can enhance the performance of PCM in mass sensing applications. In order to achieve the desired goals, we used reflection digital holography microscope (RDHM) to...
