    Abstract: Transducer structure in the nature of a thin, laminated, flexural element having evaporated film strain gages on each of two opposite surfaces. Fabrication method involving simultaneously depositing by a single-vapor source plural films of a strain sensitive electroconductive material onto insulative front surface areas of two separate or separable parts of a sheet material, to form two substantially identical bridge arm means, then bonding the two parts together, back-to-back.

    Abstract: MINIATURIZED PRESSURE TRANSDUCER FOR INTRACARDIAC AND LIKE APPLICATIONS EMPLOYING A CYLINDRICAL HOUSING HAVING A SIDE PLACED RUBBER DIAPHRAGM, AND A BEAM TYPE FLEXURE MEMBER MOUNTING FILM TYPE ELECTROCONDUCTIVE STRAIN SENSING ELEMENTS, PLACED ON THE SINGLE SURFACE OF THE BEAM AND SUBJECT T BOTH TENSIVE AND COMPRESSIVE STRAIN UPON DEFLECTION OF THE BEAM. A PLURALITY OF LEADS CONNECT THE STRAIN SENSITIVE ELEMENTS INTO A CONVENTIONAL WHEATSTONE BRIDGE CIRCUIT. A LEVER ARM OR "PADDLE" IS FIXED TO THE LOADED END OF THE BEAM AND EXTENDS GENERALLY PARALLEL TO THE BEAM AND A LINKAGE PIN INTERCONNECTS THE DIAPHRAGM AND THE LEVER ARM BELOW THE MIDPOINT OF THE FLEXURAL BEAM.
