A synthetic Jet actuator is a device which moves a fluid in and outside a cavity, through a small aperture, by the continuous oscillation of a diaphragm. The multiphysics interaction between the piezoelectric disk, which deforms due to the alternating voltage, and the fluid makes COMSOL ... Per saperne di più
We are working on a microfabricated lysing chip that uses a piezoelectric actuator to provide ultrasonic energy to break apart cells. The device contains pillars with varying dimensions. We hypothesize that increasing the aspect ratio of pillars will increase the efficiency of the ... Per saperne di più
The present work focuses on the use of piezoelectric materials as actuators for shape control of composite laminates such as Lead Zircronate Titanate (PZT), and other piezoelectric fiber composites such as Active fiber composites (AFCs), Microfiber Composites (MFCs) which allow for ...

AlGaN/GaN heterostructures are unique because the 2DEG at the interface is created by the difference in polarization properties of the AlGaN and the GaN layers; not due to intentional doping. In this work, a 3D model of an electrostatically actuated micro cantilever has been developed ... Per saperne di più
Numerous sensors based on various sensing principles are used to measure pressures and temperatures in wellbores. Of all these sensors, piezoelectric quartz is the most preferred means of sensing pressure and temperature and is probably the only sensor to meet stringent downhole ... Per saperne di più
This paper presents an ongoing effort, motivated by developing self-contained sensors for structural health monitoring of inflatable structures, to model the process of extracting useable electrical power from the mechanical vibrations of thin, prestressed membrane structures. Energy ... Per saperne di più
In order to transmit energy in one direction, sonar flextensional transducers are combined into arrays of elements that are spaced a 1/4 wavelength apart. The directionality (front-to-back pressure ratio) is a modest of 6 dB. A single projector that is 1/3 wavelength in size and capable ... Per saperne di più
Energy harvesting from environmental vibration nowadays is feasible because of natural oscillations like that caused by air or liquid flow and by exhalation or the heartbeat of a human body. This vibration frequency is typically low (in order of less than 1 kHz). Accordingly, low ... Per saperne di più
Sensors have diverse applications ranging from the medical field to space exploration. They convert physical parameters such as temperature, pressure, humidity etc. into an electrical output. The discovery of piezoresistivity property of silicon and germanium led to miniaturization of ... Per saperne di più
The use of piezoelectric materials in hearing aid loudspeakers, also called receivers, presents technical and economic advantages such as reducing the number of parts of the system and its manufacturing cost. However, the performance of such systems is still not competitive when compared ... Per saperne di più
