Researchers Demonstrate Fundamentally New Approach to Ultrasound Imaging
"Specifically, the researchers have developed a receiver that incorporates a piezoelectric crystal and an organic light-emitting diode (OLED). When an ultrasonic wave hits the crystal, it produces voltage, which causes the OLED to light up. In other words, the image appears on the OLED screen, which is built into the receiver itself."

"This is really a completely new field for ultrasound, so we’re only beginning to explore the potential applications,” Jiang says. “However, there are obvious near-term applications, such as non-destructive testing, evaluation and inspections in the context of structural health monitoring." (more)
