New Galvanic Skin Response Sensing Design from Maxim
Maxim Integrated's MAXREFDES73# improves accuracy, dynamic range, and power consumption for sensing galvanic skin response in mobile medical and fitness applications.
Maxim Integrated Products have just released a new reference design for galvanic skin response (GSR) sensing with the reference design MAXREFDES73#,
this allows wearable developers to quickly evaluate and develop wearable products for the market.
Applying GSR (measurement of skin's conductivity) is a challenge because designers need to manipulate several discrete chips and calibration software before completing the sensor design. The MAXREFDES73# integrates digital-to-analog (DAC) and analog-to-digital (ADC) converters,
a microcontroller with advanced power management, firmware, and an easy-to-use Android app into the industry's first GSR reference design.
Now designers of wearables can save development and testing time, and quickly bring their mobile medical and fitness products to market.
Offered in a wristband form factor, the MAXREFDES73# includes body surface temperature readings, Bluetooth communications,
and a rechargeable battery that lasts up to one week on a single charge.
“We based MAXREFDES73# on our award-winning MAX32600 wellness microcontroller,
and are giving wearables developers a highly integrated reference design,” said Seth Messimer,
Business Manager for Medical Microcontrollers at Maxim Integrated.
“With all the integrated components, our customers are 80% done already, saving them design and evaluation time.”
- Fast time to market: integrates DAC and ADC signal chain components, low-power microcontroller, external Bluetooth and Android apps, and firmware components to quickly develop and test designs.
- High accuracy: 16-bit integrated analog front-end (AFE).
- Low power consumption: operates for one week on one battery charge.
