What kind of waves does Embr Wave send out?

Embr Wave uses good old temperature to give you personalized thermal relief.

We've engineered our devices around the way humans feel and respond to temperature, taking thermoreceptor sensory physiology into account to provide pleasant sensations of warmth and cold without using a sizeable amount of energy.
Since humans respond the most significantly to changes in temperature, we give you temperature changes in waves, allowing your mind to keep focusing on the local sensation, bringing your body's thermal focus to your wrist.
Embr Wave transmits heat to your skin to generate sensations of warmth and removes heat from your skin to generate sensations of cold.
The radiation emitted from Embr Wave is minimal. Embr Wave is designed, tested, and manufactured to comply with FCC regulations governing radio frequency emissions and considered completely safe to use.
