The diaphragm changes the resistor of a piezoresistive element R₂. The r(t) is related to piezoresistive element Re by the following equation where R₂10002, and k₂ 200 /m. This element is connected to a wheatstone bridge and the resistors of the bridge are selected as R₁ = R₂ = R3 = 1000. Suppose the battery voltage is 10V, calculate the output voltage Vab for a step change of the amplitude 100 mmHg in the pressure p(t).
