Exploring Piezoelectrics Utilities Across Sectors

Medical ultrasound exploits the piezoelectric (http://tinyurl.com/ms3eh4fy) effect for non-invasive imaging within the human body. Pulses of voltage stimulate the piezo material to emit high frequency sound waves. As sound reflects back off internal structures, the returning echoes apply pressure on the sensor. This mechanical force gets converted back into electric signals for reconstructing tissue images.
