1. An electrosurgical pad configured to be capacitively coupled to a patient body, wherein the electrosurgical pad comprises:
return electrodes arranged in an array comprising a plurality of rows and a plurality of columns, wherein the return electrodes are configured to receive a high-frequency waveform applied to the patient body, and wherein the return electrodes comprise:
a first return electrode positioned in a first row and a first column of the array; and
a second return electrode positioned in a second row and a second column of the array, wherein the second row is offset from the first row and the second column is offset from the first column, wherein the first return electrode and the second return electrode are configured to be selectively coupled to each other and selectively decoupled from each other; and
nerve detection sensors, wherein each nerve detection sensor is configured to detect a low-frequency waveform applied to the patient body concurrently with the high-frequency waveform, wherein output signals from the nerve detection sensors are indicative of a distance between the respective nerve detection sensor and a nerve in the patient body, and wherein the nerve detection sensors comprise:
a first nerve detection sensor integrated into the first return electrode; and
a second nerve detection sensor integrated into the second return electrode, wherein respective strengths of the output signals from the first nerve detection sensor and the second nerve detection sensor are indicative of the location of the nerve along the plurality of rows and the plurality of columns of the array.
