Microbubble Generation By Piezoelectric Transducers For Biomedical Studies

MICROBUBBLE GENERATION BY PIEZOELECTRIC TRANSDUCERS FOR BIOMEDICAL STUDIES Mohammed Alkhazal Old Dominion University, 2016 Director: Shu Xiao Bubbles induced by blast waves or shocks are speculated as the major cause of damage in biological cells in mild traumatic brain injuries (TBI). Microbubble collapse was found to induce noticeable cell detachment from the cell substrate, changes in focal ...

Autonomous Wireless Heat Energy Meter based on Piezoelectric Energy Harvester for Heat Energy Measurement in Building Complexes

This paper presents a platform for power autonomous wireless energy meter device using piezoelectric energy harvesters. This device can be mainly used for measuring the share of heat energy consumption in a fair manner in building complex with central heat energy system. In the suggested device, the piezoelectric energy harvester is also used as a flow-meter to reduce the power consumption of t...

Introduction to Piezoelectric Actuators and Transducers

Certain materials produce electric charges on their surfaces as a consequence of applying mechanical stress. The induced charges are proportional to the mechanical stress. This is called the direct piezoelectric effect and was discovered in quartz by Piere and Jacques Curie in 1880. Materials showing this phenomenon also conversely have a geometric strain proportional to an applied electric fie...
