If you're wearing a sleep monitor that is awkward and gets in the way, you might choose not to use it, and even if you do, the act of wearing it might change the way you sleep.

If a sleep monitor has electrodes and wires that look like something from Frankenstein's lab, you might not wear it consistently, and the information it gathers and reports may be compromised.
In recent years wearable technology has improved drastically. Improvements in sensor technology are now making it possible to design wearable devices that are so noninvasive that we can forget we are wearing them. Inventors—myself included—are working to make sensors more accurate, smaller, with longer battery lives. The goal is to deliver great user experiences.
