  • Magnetic nanoparticle-based gyroscopic sensor
    Patent number: 10830589
    Abstract: A gyroscopic detection system utilizes magnetic nanoparticles that are suspended in a solution and exposed to a rotating magnetic field. The nanoparticles experience angular deviation from their axes if an external force is applied to the system. Solution composition and oscillation frequency may be varied to optimize the gyroscopic feedback.
    Type: Grant
