  • Maxim Integrated has released the reference design for its health sensor platform
  • This reference design integrates a PPG analog-front-end (AFE) sensor, a biopotential AFE and a human body temperature sensor with a 32-bit microcontroller

Digital health technologies can improve access to health services, reduce costs, improve quality of care and enhance the efficiency of health systems. They can also provide opportunities for self-care. Technologies that help people live healthier lives can also reduce costs for health systems.

Maxim Integrated has released the reference design for its health sensor platform. The MAXREFDES101 is a combined evaluation and development platform in a wrist-worn wearable form factor. It incorporates functions of a wide range of Maxim’s products for health-sensing applications.

Includes a variety of health monitoring modules

This second-generation health sensor platform integrates a PPG analog-front-end (AFE) sensor, a biopotential AFE and a human body temperature sensor with a 32-bit microcontroller. It also contains a power-management IC and a 6-axis accelerometer or gyroscope.

Enclosed in a watch module

This complete solution is enclosed in a watch enclosure. The back of the watch includes a biometric sensor hub. It has an embedded heart-rate algorithm.  The output of these algorithms can be streamed through Bluetooth to an Android app or PC GUI. Hence it can help in data demonstration, evaluation, and customized development of a disease detection system.

Can determine ECG, EEG and PPG 

This modular platform runs a variety of algorithms that helps in determining the ECG, EEG and PPG measurements. Additionally, it also senses basic human parameters such as heart rate, pulse rate and temperatures.

The device features two different input ports for PC synchronisation and charging. The board has a USB Micro-B port for firmware update and debugging. It also features a Micro-C type port for charging of the device. The design is compatible with a nickel-based cell which can be upgraded to lithium or nickel-based high capacity battery.
