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.
Researchers at Oak Ridge National Laboratory and the National Renewable Energy Laboratory took inspiration from flying insects to demonstrate a miniaturized gyroscope, a special sensor used in navigation technologies.Read more
Researchers from Russia and Japan have discovered a way to stabilize two-dimensional (2D) copper oxide (CuO) materials using graphene. Apart from being the chief candidates for spintronics applications, these materials may be used in upcoming quantum computers.Read more
