The traditional PZT, however, is not the ultrasonic source with high efficiency because of the serious non-coupling phenomena between air and ordinary piezoelectric material.

但由于传统的压电传感器存在着空气与普通的压电材料之间严重不耦合现象，所以压电传感器并不是高效率的超声源。

Dr Cooper and Julien Reboud, also from the University of Glasgow, have now developed a way to carry out the entire PCR process mixing, heating and cooling, as well as analysis using a single piezoelectric source, without the need for separate heating elements or detection equipment.

To get around this problem, Friend turned to a piezoelectric power source--crystals that produce electricity when under pressure.
