Abstract
A bridge array employing piezoresistive sensors responsive to the longitudinal piezoresistive effect generally exhibits a positive nonlinearity over a pressure range, while a bridge array employing piezoresistive sensors employing the transverse piezoresistive effect exhibits a negative nonlinearity over the pressure range. A composite pressure transducer is provided by interconnecting a longitudinal and transverse bridge array in a common composite configuration. The resulting transducer exhibits linear operation over the pressure range due to the cancellation of said nonlinearities from the connected arrays.
