Claim 11:
12. A surgical system, comprising:
an ultrasonic waveguide;
an ultrasonic blade extending from the ultrasonic waveguide; and
a clamp arm rotatable relative to the ultrasonic blade to capture tissue therebetween, wherein the clamp arm defines a curved surface configured to curve at least partially around a perimeter of the ultrasonic blade, wherein the clamp arm comprises a flex circuit positioned on the curved surface, and wherein the flex circuit comprises:
an electrode layer configured to transmit RF energy to the tissue positioned between the clamp arm and the ultrasonic blade;
a compressible layer positioned between the electrode layer and the curved surface, wherein the compressible layer is compressible to allow the electrode layer to move away from the ultrasonic blade;
a first pressure sensor layer positioned beneath the compressible layer between the compressible layer and the curved surface; and
a second pressure sensor layer positioned above the compressible layer, wherein the compressible layer is compressible to allow the second pressure sensor layer to move away from the ultrasonic blade.
