MIT engineers have developed a paper-thin loudspeaker that can turn any surface into an active audio source. This thin-film loudspeaker produces sound with minimal distortion while using a fraction of the energy required by a traditional loudspeaker. The hand-sized loudspeaker the team demonstrated, which weighs about as much as a dime, can generate high-quality sound […]

Providing hands-on photonics education across Massachusetts
Photonics — the science of guiding and manipulating light — enables applications ranging from telecommunications, artificial intelligence, and quantum computing to medical imaging, lidar, and augmented reality displays. But despite the importance of this growing field, the nation faces a shortage of photonics and electronics technicians and engineers. The Lab for Education and Application Prototypes […]
Professor Emeritus Markus Zahn, who specialized in electromagnetic field interactions, dies at 75
Markus Zahn, professor emeritus within the MIT Department of Electrical Engineering and Computer Science (EECS), died on March 13. He was 75 years old. Zahn was born in Bergen Belsen, Germany, in 1946, to Maria (Fischer) Zahn and Irving Zahn, each the sole survivor of their respective families during the Holocaust. The small family emigrated […]
Gina Raimondo: “Let’s get back to the business of building microchips in America”
The global semiconductor shortage, a major driver of ballooning U.S. inflation, is as much a national security issue as an economic issue, U.S. Secretary of Commerce Gina Raimondo said during a recent visit to MIT. Speaking at MIT.nano, a shared 214,000-square-foot research center for nanoscale science and engineering located in the heart of campus, Raimondo […]
More sensitive X-ray imaging
Scintillators are materials that emit light when bombarded with high-energy particles or X-rays. In medical or dental X-ray systems, they convert incoming X-ray radiation into visible light that can then be captured using film or photosensors. They’re also used for night-vision systems and for research, such as in particle detectors or electron microscopes. Researchers at […]
Physicists observe an exotic “multiferroic” state in an atomically thin material
MIT physicists have discovered an exotic “multiferroic” state in a material that is as thin as a single layer of atoms. Their observation is the first to confirm that multiferroic properties can exist in a perfectly two-dimensional material. The findings, published today in Nature, pave the way for developing smaller, faster, and more efficient data-storage […]
Credit card-sized device focuses terahertz energy to generate high-resolution images
Researchers have created a device that enables them to electronically steer and focus a beam of terahertz electromagnetic energy with extreme precision. This opens the door to high-resolution, real-time imaging devices that are hundredths the size of other radar systems and more robust than other optical systems. Terahertz waves, located on the electromagnetic spectrum between […]
Toward a stronger defense of personal data
A heart attack patient, recently discharged from the hospital, is using a smartwatch to help monitor his electrocardiogram signals. The smartwatch may seem secure, but the neural network processing that health information is using private data that could still be stolen by a malicious agent through a side-channel attack. A side-channel attack seeks to gather […]
