Answer: The exerspy armband contains multiple sensors that measure motion, body heat, skin temperature, and conductivity. A proprietary algorithm “crunches” the collected information and the user’s personal body parameters to deliver accurate information on activity, steps and calorie burn.
Motion
The armband contains an accelerometer, a device that measures motion. It's used to measure HOW you move from multiple axis and perspectives, allowing us to better understand your activity.
Steps
The accelerometer counts your steps and measures the distinct patterns created by walking and/or running.
Galvanic Skin Response
When you sweat, your skin becomes more electrically conductive. This measurement helps determine how active you are.
Skin Temperature
There's an electronic thermometer inside your armband that indicates how hot you are.
Heat Flux
When you move, your muscles produce heat. The heat flux sensor measures the heat that's flowing from your body into the environment.
