Wrist-Worn Platform for Monitoring ECG, Heart Rate and Temperature

Designers seeking to enable continuous monitoring of various health parameters can now quickly create unique, highly accurate wearable solutions using Health Sensor Platform 2.0 (HSP2.0) from Maxim Integrated Products. This next-generation rapid prototyping, evaluation and development platform MAXREFDES101#, brings the ability to monitor electrocardiogram (ECG), heart rate and body temperature to a wrist-worn wearable, reducing the development time.

 

When it comes to wearables, a wrist-based device is convenient for users to wear daily. However, it has been challenging to derive precise ECG monitoring from the wrist (most alternatives require a wearable chest strap). In addition, getting accurate body temperature typically requires using a thermometer at another location. Through its proprietary sensor and health monitoring technology, Maxim has overcome these challenges in the HSP 2.0.

 

Enclosed in a watch casing, the wrist-based form factor enables HSP 2.0 to provide basic functionality out of the box, with body-monitoring measurements starting immediately. Data can be stored on the platform for patient evaluation or streamed to a PC for analysis later. Unlike other wearables, the data measurements collected by the HSP 2.0 can be owned by the wearer, alleviating data privacy concerns and allowing users to conduct their own data analysis. Also, because HSP 2.0 is an open platform, designers can evaluate their own algorithms on the board. In addition, the modular format is future proof to quickly accommodate new sensors over time.

 

HSP2.0includes the following products:

  • MAX32630: DARWIN low-power microcontroller for wearables and internet of things (IoT) applications
  • MAX32664: ultra-low-power biometric sensor hub with embedded heart-rate algorithm
  • MAX20303: highly integrated and programmable power management solution designed for ultra-low-power wearable applications
  • MAX30205: human body temperature sensor with ±0.1 degree Celsius accuracy
  • MAX30001: ultra-low-power, single-channel integrated biopotential and bioimpedance analog front-end (AFE) solution for wearable applications
  • MAX86141: ultra-low-power optical pulse oximeter and heart-rate sensor for wearables

 

Key Advantages for Designers

  • Fast Time to Market: Fully working hardware and firmware with companion watch casing cuts design and validation time by up to six months
  • High Accuracy: Only available solution to integrate clinical-grade ECG along with heart-rate and body-temperature measurements into a wrist-worn format
  • Arm® Mbed™ Support: For efficient evaluation and rapid application prototyping, the Mbed environment provides a high level of abstraction to eliminate maintenance of software tools and provide an extensive library of open-source software

 

Availability and Pricing

Health Sensor Platform 2.0, MAXREFDES101#, is available with hardware and firmware files for $399 USD at Maxim’s website and select franchised distributors. Arm Mbed also offers the hardware, firmware and microboard.
