Wearables developers can now immediately evaluate galvanic skin response (GSR) sensing with the MAXREFDES73# reference design from Maxim Integrated Products.

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-analogue (DAC) and analogue-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.

Advantages include:

* 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 analogue front-end (AFE);

* Low power consumption: operates for one week on one battery charge.
