Latest Patents

Nicu's latest patents include a micromachined inertial sensor designed for measuring rotational movements. This invention relates to gyroscopes that feature a vibrating structure micromachined in a silicon substrate. The novel design incorporates two moving masses connected by a vibration energy coupling structure, which includes transverse arms, longitudinal arms, and a short transverse link. The moving masses are suspended from U-shaped flexure arms, allowing for independent movement. The masses are excited to vibrate in their plane through electrostatic forces, with Coriolis forces causing them to vibrate perpendicularly, which is detected by electrodes on the moving masses.

Another significant patent is a micromachined gyroscopic sensor that detects movements in the plane of the machined wafer. This microgyroscope is an inertial micromechanical sensor dedicated to measuring angular velocities. It consists of two symmetrical moving assemblies coupled via a coupling structure. Each assembly features a moving mass surrounded by a moving intermediate frame, which can vibrate in two degrees of freedom. The design allows for effective detection of vibrations while maintaining stability in the system.
