The Sensor Uses Sound Waves to Detect Objects at Extremely Small Scales

Material & Energy, Nanotechnology / Valeriano Ndeyi

Every camera relies on a sensor, whether it’s an array of light-sensitive pixels or a strip of 35mm film. But what happens when you need to photograph something so tiny that the sensor itself must shrink, causing its performance to plummet? Researchers at Northeastern University have developed a sensing technology that can detect objects as
