## What is Mosaic?

The goal of our study is to see if we can use wearable technology to measure scratching and sleep in children. We will ask you to wear some watches and come sleep in a hotel to participate in polysomnography. Polysomnography is just a fancy word for sleep study. Every day you will wear special watches that can tell us whether you are sleeping or awake as well as other motion data.

We hope you are interested in participating.
