Wearable Sensor Reveals what Overwhelms You.

There's a new wearable stress sensor that shows anxiety and it gives you an almost exact number. This device is called a Q Sensor by Affectivia. The sensor is a wristband similar to a watch with a button on it's center. This button changes color to show the battery level of the sensor. There are two silver electrodes that sends out an electric current and it runs to your skin and measures it conductance. Skin conductance rises and so does your stress level. It is being used for autistic children and other scientists want to help out drug addictions and post traumatic stress. On the sensor there is also an accelerometer to keep up the users motion. Scientist also would like to create a smart-phone app for the sensors data to be sent to the phone and let the user know if they're stressed or relaxed.
