Gyroscopes sense rotational motions to provide directional guidance without relying on satellites, so they are immune to signal jamming and other cyber threats, making them ideal for aircraft and submarines.
Integrating the devices into smaller defense and consumer electronics has been challenged by fundamental obstacles.
At micro sizes, gyroscopes’ electrical components can produce noise that interferes with their operation.
To maintain performance at microscale, the team developed an all-mechanical device with no on-chip electrical components.
The coin-sized design, fabricated at the Center for Nanophase Materials Sciences, mimics halteres, the vibrating wing-like organs flying insects use to navigate.
“Our goal was to optimize cost and performance in the smallest design possible to expand the market for this technology,” said ORNL’s Nick Lavrik.
Nanogels have emerged over the last few years as an effective vessel for carrying and releasing drugs to patients and have since become one of the many parts of nanomedicine—the interface where nanotechnology, medicine and pharmaceuticals have merged together to create their own defined field.Read more
The Lyding Group recently developed a technique that can be used to build carbon-nanotube-based fibers by creating chemical crosslinks. The technique improves the electrical and mechanical properties of these materials.Read more
