General description
The operation of the AS7038RB is based on photoplethysmography (PPG) and electrocardiogram (ECG).
PPG is the most used HRM method which measures the pulse rate by sampling light modulated by the blood vessels, which expand and contract as blood pulses through them. ECG is the reference for any measurement of the bio potential generated by the heart. The AS7038RB is supported by algorithms converting the PPG and ECG readings into digital HRM, HRV, Continuous Blood Pressure and SpO2 values. The cuff-less Blood Pressure Measurement has been optimized to fulfill the IEEE Std 1708-2014.
The detector includes the photo-sensor, analog front-end (AFE) and sequencer as well as application software. In addition to HRM/HRV, Blood Pressure and SpO2, the detector also enables skin temperature and skin resistivity measurements by providing interfaces to external sensors.
The AS7038RB’s low-power design and small from factor is particularly well suited to application in fitness bands, smart watches, sports watches and smart patches, in which board space is limited and in which users look for extended, multi-day intervals between battery recharges.
This product suits for the following applications:
- Fitness band
- Smart watch
- Heart rate and SpO2 monitors
- Cuff less blood presssure measurements
- ECG monitoring
- Optical sensor platform

Evaluation Kit for AS703x
AS703x Eval Kit
The AS703x Eval Kit is designed to evaluate all functions of the AS7030B/AS7038GB/AS7038RB biosensors and test them in various applications. For full flexibility, biosensor, temperature sensor, accelerometer and electrodes are located on the break-out board, which can be used in any application and reconnected to the main board via FPC cable. There is also the option to attach different electrodes. After breaking off the board it is also possible to connect the wristband with the PicoBlade connector. The AS703x Eval Kit works with USB connection to the PC and comes with a GUI, which enables the user to change register settings and see measurement results. The SDK contains algorithms for HRM and HRV. Any signals important for development can be probed easily at the pin headers.
