Just because it's computer simulation doesn't mean it's virtual prototyping. Our expert explains.

A recent Tech Briefs TV video demonstrated an artificial-intelligence system developed by MIT researchers. The "RF-Pose" teaches wireless devices to sense people's movement, even from the other side of a wall. See the system in action.

Researcher Jaana Vapaavuori answered an additional question regarding the future of flexible solar cells.

Simulation tools offer insight into the physical processes of heavy-duty engines. But what about natural wear and tear?

Though a flexible solar cell offers exciting, new ways of powering vehicles, clothing, and other smart technologies, manufacturing the photovoltaic component is a challenge.

Digital technologies are bringing big data, automation, and mobile capabilities to processes like IT, HR, sales, and marketing, but what is the hold-up with product development? Has your product development process been modernized and “digitized?”

A reader asks: Will it be the OEMs or the Tier-1 and Tier-2 suppliers who will be purchasing 3D metal printing machines?

There is plenty of moisture in the air — Professor Swee Ching Tan wants to harvest the humidity and put it to good use.

Most autonomous vehicles have been tested out in city environments, where tech companies like Google can build intricate 3D maps that lay out the exact position of every lane, curb, off-ramp, and street sign. But what about areas with less definable features, like country roads or a desert? An...
