How Does E-breathing Technology Work?

The patented e-breathing technology of OIZOM is a biomimicry of the human lung. Oizom devices utilize a PVDF-grade internal chamber to eliminate gas absorption and a sophisticated suction-and-exhaust mechanism to actively draw air into an internal sensor chamber and then expel it in a controlled cycle. The sensors (for gases and particulates) are mounted internally within a protective enclosure. When the device “breathes”  325 mL of air in, a small fan pulls outside air through an inlet, delivering the sample to the sensors. After measurement, the air is pushed out via an exhaust. Crucially, the enclosure shields the sensors from direct external stresses, wind gusts, precipitation, dust, and UV radiation, which could otherwise cause erratic readings or degrade the sensors.

Our sensing technology works on proven principles, including NDIR, PID, MPS Electrochemical Analysis, Semiconductor, and Optical Measurement. With this technology, the data doesn't get influenced by temperature, humidity, wind flow, or dust, and ensures the highest accuracy when combined with an isolated atmosphere.

How Does E-breathing Improve the Oizom’s Accuracy?

By isolating external environmental disturbances, the e-breathing chamber ensures more stable and precise sensor readings. This design helps our systems achieve 13% higher accuracy in measurement compared to standard passive sensor setups.

Each of our devices is calibrated using U.S. EPA-designated Federal Equivalent Method (FEM)/Federal Reference Method (FRM). The devices’ data is analyzed for 72 hrs with collocation calibration to ensure accurate data quality.

The accuracy of a real-time continuous ambient air monitoring system using e-breathing technology is evidenced by high R2 values, indicating solid correlations with reference-grade monitoring stations. Collocation tests have shown Oizom’s readings track closely to reference-grade analyzers (coefficient of determination R² > 0.90 against federal reference monitors), outperforming many other low-cost sensor devices.

Benefits of Oizom’s E-breathing

1. Data Accuracy - Ensures reliable and precise air quality measurements by actively controlling airflow to the sensors.
2. Increased Sensor Lifespan - Protects sensors from dust, moisture, and particulate overload, extending operational life.
3. Extreme Weather Protection - Shields sensors from environmental stress (heat, humidity, rain, dust storms), maintaining consistent performance.
4. Active Sampling & Multi-Parameter Monitoring - Enables continuous and representative air sampling, allowing multiple pollutants to be measured with higher accuracy.
5. Lower Maintenance - Reduces clogging, fouling, and manual cleaning needs, minimizing downtime.
6. Cost-Effective - By prolonging sensor life and reducing maintenance requirements, the overall cost of ownership is significantly lowered.

• Oizom has an edge over others on sensor-based air quality monitoring systems. We have patented the active sampling method with our e-breathing technology. The patented e-breathing technology of Oizom is a biomimicry of the human lung by inhaling 325 mL of air sample inside the system and exhaling the same amount after the sensor has generated electronic signals.
• Our devices have been collocated against reference grade monitoring stations, and R2 values achieved have been over 0.85-0.9 in most cases. This, when combined with an isolated atmosphere that does not influence temperature, humidity, wind flow, or dust, ensures the highest accuracy and also increases the sensor life of the system. The following table highlights the advantages of e-breathing technology over others.

Our sensing technology operates on proven principles, including NDIR, Electrochemical Analysis, Semiconductor, Optical Measurement, and Laser Scattering. As a part of our proprietary ‘Micro Active Sampling’ (e-breathing technology), we have a smartly designed sample intake and monitoring system inside a controlled environment. This isolates the effect of the external environment on measurement to achieve 13% higher accuracy than the industry standard.

Oizom devices use a sophisticated suction-and-exhaust mechanism to draw air into an internal sensor chamber actively, then expel it, in a controlled cycle.
