Spinoff: Wireless Platform Integrates Sensors with Smartphones

The platform, developed using NASA nanotechnology, paved the way for interchangeable smartphone 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, Ames Research Center scientist Jing Li had a ready response. Four years earlier, she led a team that wrote a paper on the use of carbon nanotube sensors for gas and organic vapor detection.

Designing for 3D Printing

3D printing has progressed over the past decade to include multimaterial fabrication, enabling production of powerful, functional objects. While many advances have been made, it still has been difficult for non-programmers to create objects made of many materials (or mixtures of materials) without a more user-friendly interface.

New Fabrication Technique Creates More Efficient Plastic Solar Cells

Schematic of a sequentially cast ternary (SeCaT) solar cell. (Peter and Ryan Allen) Researchers from North Carolina State University have developed a new strategy for fabricating more efficient plastic solar cells. The work has implications for developing solar cells with a wider absorption range and increased efficiency.

Technique Could Lower Costs of Making Bioplastics and Biofuel

Ulrica Edlund, professor of polymer technology. While abundant in nature, cellulose is difficult and expensive to find in pure or high-quality form. A Swedish research team has developed an efficient, accurate, and non-destructive way to detect the occurrence and purity of cellulose. The technique can be applied in mixtures of biopolymers as well.

Precision Coffeemaker Adapts Brews to Beans and Taste

NASA’s embedded communications technology and PID controllers play key roles in coffee brewing system.Technology often takes circuitous paths. A magnetron developed for precision bombing during World War II led to the microwave oven, and a battery-powered drill created for collecting samples of Moon rock gave birth to the Dustbuster. Likewise, one student’s NASA experience with autonomous robotic vehicles has informed the creation of one of the world’s most sophisticated coffee machines.
