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 the 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 the 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 a direction of the radial on-plane force on the second circle point, are orthogonal.
