FIG. 5.2 A schematic of a full Wheatstone bridge circuit with four variable resistors. These resistors represent the piezoresistors mounted on the diaphragm of a MEMS pressure sensor. When the sensor diaphragm remains undeformed, the bridge is balanced, and no signal is detected between points 1 and 3. However, in the presence of an external pressure field, the diaphragm of the sensor deforms, and the resistances of the piezoresistors change. This creates an imbalance in the circuit resulting in a proportional voltage change across the bridge (between points 1 and 3), which is then measured to calculate the pressure changes (Sheela et al.).
