  • Pendulum with bending spring joint
    Patent number: 4953834
    Abstract: A micromechanical bending spring joint is formed of selectively etched wafer material. The joint includes a pair of leaf springs arranged alongside each other. Each spring is inclined at an oblique angle to the opposed surfaces of the wafer and such springs cross to define a point of intersection. The joint, selectively etched from a single wafer, is characterized by high precision of fulcrum position, bending spring constant and transverse axis rigidity.
