A single-use sensor is placed on the patient's forehead before surgery and is worn throughout the perioperative journey.
Unlike passive skin surface temperature sensors, the SpotOn system's single-use sensor consists of a thermal insulator adjacent to the skin which is covered by a flex circuit. Once connected to the SpotOn control unit, the flex circuit actively regulates its temperature to create a zone of perfect insulation - a condition where heat loss to the environment is eliminated.
