Intended for developers of small, battery-powered, continuously wearable devices, this AFE on a chip offers clinical-grade vital sign measurements of bioimpedance analysis for patient health assessment using wellness wearables and medical-grade patches.
Many vital signs monitors, chest patches, stress monitors, BioZ and wearable healthcare devices ned to be able to operate on a small battery as part of small, compact designs that also emphasize convenience and comfort.
The MAX30009 is a low-power design with a range of options to enable use-case power optimisation that reduces the draw on tiny batteries, helping to extend the operational life of BioZ wearables. According to ADI, the device reduces power consumption by 62 percent compared to the closest competitive product and extends measurement periods for body-worn patches, and vital signs monitoring devices.
The highly integrated AFE is also 30 percent smaller than the closest competitor, allowing designers to reduce the size of vital signs measurement devices, making them more comfortable and convenient for consumers and patients.
Bioimpedance analysis devices are becoming increasingly popular among healthcare professionals looking to measure body fat percentage and body composition (such as respiration and impedance cardiography.) The MAX30009 monitors a comprehensive range of BioZ modalities through simultaneous I and Q measurements, 2-electrode (bipolar) and 4-electrode (tetrapolar) configurations. This enables flexible inputs for BioZ modality measurements as well as a wide range of sample rates to support various medical BioZ measurements.
A wider range allows more profound insights into patient health by measuring respiration rate, galvanic skin response and electrodermal activity, body composition and fluid analysis, bioimpedance spectroscopy, impedance cardiography and plethysmography.
