Abstract: An accelerometer includes a base, a proof mass flexibly connected to the base, and a double-ended tuning fork (DETF) coupled to the proof mass and the base. The DETF includes a base attached to the accelerometer base, an outrigger that extends from a first side of the base, and two tines that extend from a side of the outrigger that is opposite the first side of the base. The accelerometer also includes a drive mechanism that generates opposing forces in different halves of the outrigger, thereby causing the tines to oscillate. An excitation voltage applied to metallized traces on the outrigger at the base of the DETF cause the tines to resonant. The alternating strains generated at the root of the tines excite the tines themselves at their resonant frequency without the requirement of complex metallization applied to the tines.
