Scientists from the max Planck institute for Intelligent Systems, University of Stuttgart and IMS CHIPS develope ultrasound projector on base of a CMOS chip [ Picture: IMS CHIPS] Scientists of the Micro, Nano and Molecular Systems Lab at the Max Planck Institute for Intelligent Systems and the Institute of Physical Chemistry at the University of Stuttgart have developed a digital chip that can be used to project movies with ultrasound. The researchers report on this in an article in the magazine "Nature Communications". The ultrasound projector is based on a special microchip that was developed and manufactured at the Institut für Mikroelektronik Stuttgart (IMS CHIPS). The chip generates targeted micro bubbles that can be switched on and off digitally (via the chip) in rapid succession. This makes it possible for the first time to protect high-resolution holographic images that change with the time. Ultrasound is widespread in applications from medical imaging and industrial inspection to therapy and tissue ablation in surgery. While sophisticated technologies exist to detect and analyze ultrasound, the generation and projection of ultrasound is still fairly basic.
