  • MEMS sensor structure comprising mechanically preloaded suspension springs
    Patent number: 11267694
    Abstract: A MEMS sensor comprising preloaded suspension springs and a method for mechanically preloading suspension springs of a MEMS sensor are described. The MEMS sensor comprises a MEMS support structure; a plurality of suspension springs connected to said support structure; and, a proof mass flexibly suspended by said suspension springs; wherein at least one of said suspension springs is mechanically preloaded with a compressive force for reducing the natural frequency of said proof mass.
    Type: Grant
    Filed: July 14, 2020
    Date of Patent: March 8, 2022
    Assignees: STICHTING VU-VUMC, FOM-NIKHEF
    Inventors: Eric Hennes, Alessandro Bertolini, Johannes Franciscus Van Den Brand
