An electrical device for measuring physiological pressure phenomena, using a resistance wire strain gauge, is described. The gauge is bonded securely to a metal diaphragm, deformation of which changes the resistance of the gauge, and causes a flow of current through an appropriate circuit. Examples of the applications in physiology of this device are presented along with typical recordings.
