Abstract
An electrosurgical grounding pad has a temperature sensor to prevent skin burns. A paraffin insulated conductor is embedded in a conducting gel medium so that before a burn-producing temperature exists, the insulation melts and connects the conductor to ground. An alarm detects the presence of the ground and alerts operating room personnel of the burn condition.
