A large-area, flexible, ultrasonic imaging system with a printed organic transistor active matrix

We have successfully fabricated a large-area, flexible, ultrasonic system by integrating a two-dimensional polymeric ultrasonic sensing array with a printed organic transistor active matrix. The new sheet-type device can offer a cost-effective solution for a real-time three-dimensional imaging in free space and/or a large-area proximity sensor for robot skins.
