Working Principles of Medical Oxygen Sensors
Electrochemical sensors operate by generating a current proportional to the oxygen concentration in a sample. This current is measured and converted into an oxygen level reading. These sensors are highly accurate but require regular calibration to maintain performance.
Optical sensors use light absorption techniques, where oxygen molecules absorb specific wavelengths of light. The amount of light absorbed is directly proportional to the oxygen concentration. This method is non-invasive and ideal for continuous monitoring.
Paramagnetic sensors rely on the fact that oxygen is a paramagnetic gas, meaning it is attracted to magnetic fields. By measuring the force exerted on a magnetic field, these sensors can determine oxygen levels. Zirconia-based sensors, meanwhile, use the ionic conductivity of zirconium dioxide to measure oxygen partial pressure.
Here is a list of the working principles of different oxygen sensors:
- Electrochemical: Measures current from oxygen reactions.
