A Piezoelectric Micropumping Device
ASME 2009 Second International Conference on Micro/Nanoscale Heat and Mass Transfer, Volume 1, 2009A dynamic micropumping device has been developed, which is based on acoustic streaming generated by a piezoelectric microtransducer actuated in d31 mode without any check valve. Piezoelectric microtransducers immersed in liquid (water) are used as actuators due to some of their unique properties such as lower noise generation and ease of ...

International Journal of Modern Physics B, 2010
This paper introduces a new based-on ultrasonic wave micro-fluid driving technique that is different from the present principle. The standing wave is generated by ultrasonic vibration in the device, and acoustic field is generated simultaneously. The particles in fluid medium of the device move towards the node of the standing waves caused by the ...

Piezoelectric biosensors: Strategies for coupling nucleic acids to piezoelectric devices
Methods, 2005The development of a piezoelectric biosensor based on nucleic acids interaction is presented focusing on the methodology for probe immobilization. This is a key step in any DNA biosensor development. Often, the detection limits and, in general, the analytical performances of the biosensor can be improved by optimizing the immobilization of the receptor
