1. An end effector, comprising:
an ultrasonic blade; and
a clamp arm pivotable relative to the ultrasonic blade to capture tissue therebetween, wherein the clamp arm defines an arcuate surface configured to at least partially surround the ultrasonic blade, wherein the clamp arm comprises a circuit positioned on the arcuate surface, and wherein the 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 arcuate surface, wherein the compressible layer is compressible to allow the electrode layer to deflect away from the ultrasonic blade;
a first pressure sensor layer positioned beneath the compressible layer between the compressible layer and the arcuate 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 deflect away from the ultrasonic blade.
