Columbia researchers have developeed a new optical phased array on chip at both near-infrared and blue wavelengths. It could advance autonomous navigation, augmented and virtual reality, and neuroscience.

Researchers at Columbia University claimed to be the first to develop and demonstrate a robot finger with a highly precise sense of touch over a complex, multicurved surface.

By adding electronics and computation technology to a simple cane that has been around since ancient times, a team of researchers at Columbia Engineering have transformed it into a 21st century robotic device that can provide light-touch assistance in walking to the aged and others with impaired mobility. A team led by Sunil Agrawal, professor…
