Researchers have taken inspiration from flying insects to demonstrate a miniaturized gyroscope, a special sensor used in navigation technologies. 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 the micro scale, the researchers 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.
