a Leakage current: MMAT-OCT complies with FDA’s safety limit (0.1 mA) for cardiac floating-type devices. b Voltage characteristics: The MMAT-OCT’s 304 stainless steel stopper exhibits a voltage amplitude <0.02 mV, measured at 200 mV and 50 Hz using an oscilloscope and signal amplification filter circuit. c Clinical relevance: Intraluminal temperatures exceeding 41 °C are associated with esophageal ulceration. d Temperature monitoring: MMAT-OCT probe temperature, monitored by a thermal camera over 45 min, showed minimal fluctuations within ±0.5 °C from ambient conditions.
