ams introduces sensor reference design for blood pressure, vital signs for smart health and wearables

ams announced the release of the first integrated vital sign sensor reference design based on its AS7024. The solution can perform accurate, fast and convenient 24/7 cuffless blood pressure measurement.

The new vital signs sensor reference design based on AS7024 integrates all the hardware components, including the AS7024, as well as the software required to implement blood pressure measurement, heart-rate measurement (HRM), heart rate variability (HRV) and electrocardiograms (ECG). The AS7024 sensor IC includes three LEDs, photodiodes, an optical front end and sequencer for HRM, and an analog front end for ECG in a low-profile 6.1mm x 2.7mm package. The reference design also enables calculated measurements of vagal tone and arterial elasticity, as well as skin temperature and skin resistivity via interfaces to external sensors.

The AS7024’s small form factor is particularly well suited for fitness bands, smart watches, sports watches and smart patches, in which board space is limited. It also opens the door for vital sign monitoring to a wider range of form factors and end markets such as automotive or personal health monitoring (more info).
