NASA-Developed Platform Integrates Sensors with Smartphones

Carbon-nanotube-based gas detectors paved the way for interchangeable smartphone-savvy sensors. In 2007, when the Department of Homeland Security (DHS) issued a call for a sensor that could equip a smartphone with the ability to detect dangerous gases and chemicals, NASA Ames Research Center scientist Jing Li had a ready response. She had been developing the use of single-walled carbon nanotubes that respond to various gases and compounds for use in NASA applications such as evaluating planetary atmospheres, detecting chemicals around rocket launch pads, and monitoring the performance of life-support systems. Her proposal was awarded funding in 2008, but she needed a way for the device to “sniff” the air for samples, and a system that would allow it to interface with a smartphone.

Tech Briefs 40th Anniversary: Executive Perspectives

We asked executives to offer perspectives on milestones in their industry or technology area that occurred during the past 40 years. Did their industry exist 40 years ago, and if not, what brought about its creation? Maybe it experienced its greatest growth during that time. And what are their expectations for the coming years?
