ams AS7038RB Vital Sign Sensor
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.
ams AS7050 Medical and Health Sensor - Analog Frontend
The AS7050 Biosignal Sensor Analog Frontend is the next generation Vital Sign Sensor. It enables the user to detect biosignals such as photoplethysmogram (PPG), electrocardiogram (ECG) and galvanic skin resistance (GSR). PPG is the most used HRM method. It 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 biopotential generated by the heart. Compared to the previous ams-OSRAM biosignal sensor generation, AS7050 is a biosignal converting unit. The AS7050 provides up to 8 LED driver outputs, samples up to 6 photodiode inputs and supports external electrodes. This enables the highest flexibility for several LED and photodiode arrangements in different applications. Furthermore, the AS7050 Biosignal Sensor Analog Frontend provides 2 ADC channels for simultaneous PPG and ECG measurements and an automatic photodiode offset control. The embedded ECG analog front-end satisfies IEC 60601-2-47 requirements.The AS7050’s low-power design and small form factor are particularly well suited to application in fitness bands, smartwatches, sports watches, smart patches and earbuds. In these cases, board space is limited, and users look for extended, multi-day intervals between battery recharges. Thin package dimension makes the AS7050 suitable for height constrained solution likes earbuds.

The AS7056 Biosignal Sensor Analog Frontend (AFE) is the next generation Vital Sign Sensor. It enables the user to detect biosignals such as photoplethysmogram (PPG) and pulse transit time (PTT), as well as proximity. PPG is the most used HRM method. It measures the pulse rate - by sampling light modulated by the blood vessels, which expand and contract as blood pulses through them. Apart from HRM/HRV, optical Blood Pressure and SpO2 are also enabled by the two independent working photodiode inputs of the AS7056. The AS7056 is a size and performances optimized analog frontend to support space-limited applications such as in-ear vital sign monitoring.The AS7056 provides two LEDs and one VCSEL driver outputs, samples up to three photodiode inputs, and supports proximity detection integrated into one of the PPG signal channels. This enables high flexibility for several LED and photodiode arrangements in different applications.
