Figure Lengend Snippet: FEA simulation result of the winged sensor – used with the Type F packages – with the wings anchored. The sensor resonates at 169 kHz in a longitudinal mode shape with a maximum displacement of 30 nm.
Article Snippet: For a 12.5 mm long and 1 mm wide ribbon sensor fabricated from MetglasTM 2826MB (£, = 100 GPa, p s = 7.90 g/cm 3 ), the expected resonant frequency is 168.7 kHz, which is confirmed by the finite element analysis (FEA) result (COMSOL Multiphysics) [ 11 ], For the sensor used in the Type F package, two additional 0.8 mm × 0.4 mm wing features with two Ф0.3 mm tether holes are located in the middle of the sensor for anchoring it in the package.
