What is the technology used in the PowerWatch?
The PowerWatch uses a thermoelectric generator (TEG) that senses body heat and converts it into energy. TEGs need to have a hot side and a cold side to operate. The hot side is the circular black aluminum plate on the back of the watch. The cold side is the entire metal bezel and body of the watch. The hot and cold sides are separated from each other by a layer of insulating thermoplastic. The TEGs harvest the heat flowing from the hot side to the cold side and turn it into electricity.
How does the PowerWatch use this electricity?
The PowerWatch has a small battery inside that is charged constantly whenever you wear the watch. This battery maintains the time and fitness data when you are not wearing the PowerWatch, for up to one year.
What is the Real Time Display?
The Real Time Display is the display bars visible around the outside of the watch face during many watch functions. These indicate how much power is being harvested from your body heat. When you turn on the PowerWatch and place it on your wrist, these bars activate starting at 12 and moving clockwise around the watch. For most people, the Real Time Display will stabilize between 6 and 9 bars. Exercise and other activities can increase this display all the way to 11.
How much power can the PowerWatch generate?
In order to charge its internal battery, the MATRIX PowerWatch requires a temperature differential with the ambient air. It can generate more power when the air is cooler, and also when you are active and your skin is warmer. Here is a chart that shows how fast the PowerWatch will charge its internal battery at different air temperatures:
As you can see on the chart, the PowerWatch will charge its battery most quickly when you are active (walking or running), and when the ambient temperature is below 80 °F. Above 90 °F, the PowerWatch cannot charge its internal battery. In the case that it is unable to charge, the watch will work for up to 1 year. Not covering the watch with a shirt sleeve, wearing the watch snugly on the wrist, and allowing the arm to swing naturally during physical activity will all boost the rate of energy production.
What’s the best way to show the PowerWatch to my friends?
Here’s how we do it: Take off the PowerWatch, then wait until the Real Time Display shows zero bars. This could take a minute or two, but you can shorten the time by setting the PowerWatch on a cool table.
Then ask someone to hold out their wrist. Set the PowerWatch on their wrist and show them the Real Time Display bars increasing. You can even say, “Thank you, your body heat just charged my battery!” You can repeat this with several different friends, to see who generates the most power.
Don’t strap the watch to their wrist for this demo, because the bars will stop moving by the time they get the strap fastened. It’s more fun to see the bars moving, then fasten the strap later if they want to play with the other PowerWatch features.
