Non-invasive medical sensors are devices used to monitor various physiological parameters without piercing the skin or entering the body.

These sensors are crucial for continuous patient monitoring in both hospital and at-home settings, providing valuable data for diagnosis and treatment. Examples include pulse oximeters, ECG devices, and infrared thermometers.
Key types and examples of non-invasive medical sensors:
Pulse Oximetry: Measures blood oxygen saturation (SpO2) and heart rate, commonly used in hospitals and by individuals managing respiratory conditions.
Electrocardiogram (ECG): Measures electrical activity of the heart, often using wearable devices like smartwatches or chest straps to provide continuous monitoring.
Infrared Thermometers: Measures temperature from a distance, useful for quick temperature checks without physical contact.
Transcutaneous Electrodes: Used to measure oxygen and carbon dioxide levels in the blood through the skin, according to Oxford Academic.
Transcutaneous Bilirubin Monitors: Used to assess bilirubin levels in newborns, avoiding painful blood draws.
Non-Invasive Blood Pressure Monitors: Measure blood pressure without the need for a needle or cuff insertion.
Continuous Glucose Monitors (CGMs): Measure blood sugar levels in real-time, used by individuals with diabetes.
