1. A planar microelectromechanical gyroscope structure comprising:

  • a circular structure that extends around a center point;

    a central spring structure for suspending the circular structure to four central anchor points, symmetrically located around the center point;

    four central circle points and four peripheral circle points between the central circle points on the circular structure, neighboring ones of said four peripheral circle points forming a pair of peripheral circle points and neighboring ones of said four central circle points forming a pair of central circle points,wherein the central spring structure is configured to connect each of the four central anchor points to a pair of central circle points on the circular structure,wherein a connection between the central spring structure and the circular structure is configured to transform a radial on-plane displacement of a first circle point of a pair of peripheral or central circle points to a reverse radial on-plane force on a second circle point of the pair of peripheral or central circle points,wherein a direction of the radial on-plane displacement of the first circle point, and the direction of the radial on-plane force on the second circle point, are orthogonal.
