A strain gauge blood pressure sensor is built from p-type semi-conductor. Eight small strain gauges with a nominal resistance R=100ohm and a gauge factor G=100 are placed on a small round disk (5mm diameter) of silicon substrate. They are connected in a bridge as shown below. Calculate the voltage output of the bridge, Va-Vb for a voltage input of 1V

Answer rating: 100% (QA)

To calculate the voltage output of the bridge VaVb we need to consider the Wheatstone bridge configuration and the behavior of strain gauges In a Whea... View the full answer
