The electrosurgical pencil (10) 10 also includes an activation button (24) electrically coupled to the blade, a strain gauge (30) affixed to the electrocautery blade for measuring a displacement of the blade, wherein the strain gauge (30) is sensitive to a temperature change associated with the electrocautery blade (16) and a compensator resistor operatively connected to the strain gauge (30). The compensator resistor is configured to compensate for changes in is temperature of the electrocautery blade (16) that effect the strain gauge (30).
