Designers now have an easier way to deliver photoplethysmogram (PPG) and electrocardiogram (ECG) measurements for health monitoring from a mobile, battery-powered device. The new MAX86150 from Maxim Integrated is a biosensor module, comprised of internal LEDs, photodetectors and an ECG analogue front-end (AFE) to provide highly accurate, FDA-certifiable PPG and ECG performance in compact, power-saving designs, including mobile phones, laptops, tablets and smart speakers.
Delivering synchronised PPG and ECG measurements has been challenging because designers have had to utilise two separate biosensors that together consume more board space and power than a mobile device can typically afford.
In addition, achieving high accuracy in the measurements has also been challenging, particularly in cases where sensor sensitivity might be impacted by low perfusion levels or dry skin.
The MAX86150 overcomes these challenges, sampling both PPG and ECG simultaneously to provide the highest sensitivity of pulse transit time. To reduce battery drain, the module can be shut down through software with near-zero standby current, allowing the power rails to remain powered at all times. The MAX86150 is available in a 3.3x6.6x1.3mm, 22-pin optical module.
“At-home healthcare monitoring contributed to a 35% reduction in hospital visits in 2017. With access to integrated cardio health monitoring from their fingertips, users will be able to keep close tabs on their well-being.” - Global Industry Analysts.
“The MAX86150 is another important breakthrough at Maxim, continuing the company’s push to enable a healthier world. With highly accurate heart-rate measurements from a compact, low power device, consumers will be empowered to be more proactive about their healthcare,” said Mohammad Zarghami, Executive Business Manager, Industrial and Healthcare Business Unit at Maxim Integrated.
