Sophisticated antenna arrays paired with high-frequency wireless chips act like superpowers for modern electronics, boosting everything from sensing to security to data processing. In his lab at Princeton, Kaushik Sengupta is working to expand those powers even further.

In recent years, Sengupta’s lab has designed antenna arrays that help engineers make strides toward peering through matter, boosting communications in canyons of skyscrapers, putting a medical lab on a smart phone, and encrypting critical data with electromagnetic waves instead of software.

In a new article in Advanced Science, Sengupta’s research team presented a new type of antenna arra...

It took just over 10 years, but real science has finally caught up to the science fiction of Iron Man’s transforming exoskeleton suit. Engineers at Brigham Young University detail new technology that allows them to build complex mechanisms into the exterior of a structure without taking up any actual space below the surface.

This new class of mechanisms, called “developable mechanisms,” get their name from developable surfaces, or materials that can take on 3D shapes from flat conformations without tearing or stretching, like a sheet of paper or metal...
