Abstract
Piezoresistive deflection-sensitive beam elements are encapsulated in a disc of elastomeric material which forms a fluid pressure responsive diaphragm. The beam elements are oriented within the diaphragm so as to be strained in tension or compression when the diaphragm is deformed by fluid pressure. The beam elements are connected in a bridge circuit to produce an electric signal which provides a fluid pressure indication or measurement, as in a blood pressure monitoring catheter.
