Summary:Various forms are directed to systems and methods for coagulation and dissection of tissue. A surgical instrument includes an end effector configured to seal and dissect tissue at a distal end thereof and a generator circuit that is configured to deliver energy to the end effector. A force sensor is in communication with the end effector and is configured to measure a force being applied to the tissue by the end effector. The energy delivered to the end effector is dynamic based on a determination of the type of tissue interacting with the end effector. The tissue type is determined based on a tissue coefficient that is calculated based on the measured force applied to the tissue by the end effector, the ultrasonic motion of the end effector, and a rate of heat generated by the end effector.
