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.
Scientists develop new method to isolate atomic sheets and create new materials
Two-dimensional materials from layered van der Waals (vdW) crystals hold great promise for electronic, optoelectronic, and quantum devices, but making/manufacturing them has been limited by the lack of high-throughput techniques for exfoliating single-crystal monolayers with sufficient size and high quality.
Physicists at the University of Groningen have now imaged hydrogen at the titanium/titanium hydride interface with the help of a transmission electron microscope.Read more
