The Wonders of Waves - Future Technologies Built on Basic Research

In the future, a regular physical examination may not be necessary to identify any potential health crises. Instead, a smart device in a mirror will report to us any anomalies in our body and provide health recommendations when we wake up every morning. This sort of assessment will be made possible by airborne ultrafast ultrasonic imaging technology, in which a time-reversal device records a video of skin vibrations at 1,000 frames per second. Details unnoticed by human eyes are compared to population data and can serve as first screening tools of medical conditions. Such technology is not science fiction, but an actual study in progress by IAS Visiting Professor Mathias FINK.
