SUMMARY
The discussion centers on the advantages of using a half Wheatstone bridge over a full Wheatstone bridge in strain measurement applications. While a full bridge configuration provides double the sensitivity (Vout = NEGS/4 with N=4), a half bridge requires only half the number of strain gauges, making it a cost-effective solution. Additionally, the reduced wire count for a half bridge is beneficial for remote sensors, where minimizing impedance wire count is crucial. The choice between configurations also depends on the specific application and type of strain being measured.
