Researchers from North Carolina State University developed a new technique that could drastically lower the cost of ultrasound acoustic imaging, using OLED displays. The researchers say that ultrasound receivers could be made with costs of around $100 - compared to current systems which cost $100,000 or more.
The researchers fabricated an OLED on top of a piezoelectric transducer. When ultrasonic waves interact with the transducer, it lights up the OLED display. This create a very simple ultrasound device compared to current devices.
