Design a piezoelectric accelerometer as shown below to detect
heart beats. Assume for this application, the lower 3dB frequency
fL needs to be 1 Hz. The cantilever has a
dimension of 6 mm x 4 mm x 1.5 mm (L x W x H) and is made of
aluminum, with a Young’s modulus of 69 GPa. The rigid proof
mass has a dimension of 20 mm x 10 mm x 5 mm (LM ´
WM ´ HM) and a mass of 10 gram.
