Latest Patents

Vesterinen's latest patents include a MEMS accelerometer with a mechanically decoupled proof mass. This invention aims to reduce errors in accelerometer output by allowing the proof mass to move along at least two perpendicular axes while being mechanically coupled to the measurement structure along the sense axis. This design ensures that movement perpendicular to the sense axis does not affect the measurement structure. Another significant patent is the low-noise multi-axis MEMS accelerometer, which utilizes a larger, single proof mass to measure acceleration along two orthogonal axes. This innovative design incorporates a novel arrangement of electrodes to prevent cross-axis errors and further reduces noise through unique spring arrangements and proof mass layouts.
