Technology Powers Implants Wirelessly Via Ultrasound

Scientists have developed a demonstrator that powers active implants wirelessly via ultrasound. Ultrasound waves have a broader range in the body, and they penetrate the implant’s metal casing more easily than electromagnetic waves. The ultrasound waves are also capable of bidirectional...

Standing Still May Improve Antennas That Scan in All Directions

Antennas often need to trace circles in the sky. For example, radar arrays atop air-traffic control towers rotate to sweep signals in all directions. But spinning large objects nonstop takes a lot of time and mechanical energy. So scanning from a stationary position could speed up...

New MRI Technology Eliminates Longtime Limits

A new technology harnesses imperfections that typically compromise MRI exams to create images resolved enough to enable consistent diagnoses across populations for the first time. Traditional MRI radio waves “light up” some parts of a sample better than others, with imperfections blacking out...

Flexible Skin Traps Radar Waves and Cloaks Objects

Iowa State University engineers developed a new flexible, stretchable, and tunable metamaterial skin that uses rows of small, liquid-metal devices to cloak an object from the sharp eyes of radar. By stretching and flexing the polymer meta-skin, it can be tuned to reduce the reflection of a wide...

NASA Flight-Tests Sample Return Capsule

A prototype capsule that one day will return science experiments to Earth was tested by releasing it from a high-altitude balloon. Technology like this capsule could one day return biological samples and other small payloads from space in a relatively short time. The balloon was launched to an altitude of...
