Maxim Integrated has recently announced two wearable development kits for fitness / health tracking:
- MAX-HEALTH-BAND watch for vital signs
- MAX-ECG-MONITOR with a chest strap for clinical-grade electrocardiograph (ECG) and heart rate.
The MAX-HEALTH-BAND wrist-worn heart-rate and activity monitor features the company’s MAX86140 optical pulse-oximeter/heart-rate sensor, MAX20303 wearable power-management solution, and Maxim’s motion-compensated algorithms.
The watch sends raw PPG and accelerometer data via Bluetooth to a smartphone app, and also monitors steps, activity, heart rate and interbeat intervals for heart-rate variability measurements. Battery life is around 7 days on a single charge.
The kit also includes a USB charging cable, and instructions to download the Android-based application. The evaluation platform can be used for the development of fitness and wellness trackers, health monitoring trackers, or as a experimentation platform for new use cases and algorithms.
In addition to raw PPG and accelerometer data, the MAX-HEALTH-BAND monitors steps, activity, heart rate, and interbeat intervals for heart-rate variability. The MAX-HEALTH-BAND comes with a wrist-worn heart-rate and activity band, a USB charging cable, and instructions for downloading the Android-based application. You’ll find the later and other user & development resources on the product page. The watch kit can be purchase for $200 by selecting the order tab.
The MAX-ECG-MONITOR evaluation/development platform features the MAX30003 ultra-low-power, clinical-grade analog front end (AFE) used to monitor ECG and heart-rate signals. Two form factors are offered for the kit: a wet electrode patch for clinical applications, and a chest strap for fitness applications.
The monitor also sends real-time raw data from the sensors – AFE, accelerometer, gyroscope, and magnetometer – over Bluetooth to an Android app which store the data, and allows analysis of the data.
The MAX-ECG-MONITOR also comes with an ECG/heart-rate monitor reference design module with embedded firmware, chest strap + dry electrodes, or wet electrodes, as well as instructions for downloading the Android based application.
Typical applications include athletic stress testing, fitness and health monitoring apparels, fitness monitoring chest strap, and medical heart-rate signal patches.
Again, you’ll find all development resources on the product page, where you can also purchase the evaluation platform for $150.
