Development of a new kind low frequency low-noise vector sensor

[Display omitted] •A new kind low frequency low-noise vector sensor composed with a built-in accelerometer and a JFET-based preamplifier was developed.•A novel structure of accelerometer with cross-ring beam was proposed using relaxor-based ferroelectric crystals.•The self-noise of vector sensor was...
