Origins
Wearable devices have made our lives more convenient, making it easy to measure various vital signs, such as blood oxygen saturation, heart rate and blood pressure. Many well-known manufacturers have also introduced new products and continued to develop more accurate products with more functions.
When communicating with our clients, we learned that to obtain more accurate test results, engineers very much hope to have a device that can flexibly set the AC, DC, waveform, frequency and amplitude of R or IR when designing the blood oxygen function. They need a simulator to verify test challenges at each stage, such as signal processing, frequency response, system integration verification, etc.
Therefore, the AECG100 + PPG-2R-880/PPG-2R-940 Reflectance SpO2 Module came into being, which not only meets the flexible setting of PPG waveforms expected by engineers, but can also adjust the characteristic points of the waveform in a wide range and in detail. You can also customize your own R curves, no longer need to conform to established templates.
Also, with the original ECG function of AECG100, it can simultaneously send out ECG and PPG signals, adjust the parameters of Pulse Wave Transit Time (PWTT), and thus verify the accuracy of the blood pressure measurement algorithms.
In addition to the complete functions and flexible testing mentioned above, we also learned from our customers that engineers often need to quickly verify products before mass production. The PPG-2R-880/PPG-2R-940 module can automatically calculate the R/IR DC value of the DUT and import it into the SpO2 table, quickly establishing an exclusive R curve, and efficiently verifying product quality. PPG- 2R-880/PPG-2R-940 also contains the function of simulating respiratory changes, which can be superimposed on the test to get closer to the real situation and make it more comprehensive.
To conduct testing more efficiently, we also provide a free Software Development Kit (SDK), which enables them to develop automated testing software by themselves, flexibly expand testing capabilities, and reduce human errors that may result from repeated settings and operations. We can use the PPG-2R-880/PPG-2R-940 module to accurately test wearable devices, ensure accuracy and consistency, and meet product specification requirements.
