Carbon nano tubes have potential biomedical applications as sensors and diagnostic tools due to their unique properties. They are strong yet light, chemically stable, and have rich electronic properties. As piezoresistive sensors, carbon nano tubes have a temperature coefficient much lower than silicon, making them stable sensors. They can be used in applications like blood pressure monitors, inflatable mattresses, and intelligent respiratory devices. When pressed or deformed, a carbon nano tube's electronic properties change depending on the deformation amount, allowing it to detect physical quantities.
