How about recharging your connected watch … with your skin?


Every day, in his column “The innovation of the day”, Anicet Mbida gives us what is best in terms of new technologies. Tuesday, he looks at a new technique developed by an American university that converts heat naturally lost by the human body into electricity.

What if our bodily energy means the end of the batteries in watches and other connected bracelets? This is the idea behind a connected watch, still at the prototype stage, manufactured by the company Matrix Industries. Tuesday, in his column “The innovation of the day”, Anicet Mbida presents this technology developed by the American University of Boulder, Colorado. Concretely, this process converts the heat naturally lost by our body into electricity. Because if the internal temperature of a human being is 37 degrees Celsius, it is only 33 or 34 degrees Celsius outside.

One volt per square centimeter

The technique that generates about one volt per square centimeter of skin. It’s not much, but applied over the entire surface of a bracelet, this technology generates five volts. Largely sufficient to power a watch, a blood glucose sensor or a connected bracelet. The researchers are also considering adapting this technology for pacemakers: this would prevent patients equipped with this device from having to go back to the operating table to change the battery. An operation certainly harmless but which is not free from possible complications.

For the moment, only the connected watch of Matrix Industries is equipped with this technology which would put an end to the batteries. It is therefore necessary to be patient more to see the end of the batteries in the watches.
