The Power Of My Wrist
Dyson Energy Bracelet is a gadget that uses Seebeck effect to harness energy and power your mobile phones for a few precious minutes more, when you desperately need it. Lemme explain a bit: The thermoelectric effect is the direct conversion of temperature differences to electric voltage and vice versa. This typically includes three separately identified effects, the Seebeck effect, the Peltier effect, and the Thomson effect. This is coz three different guys discovered it around the same time, however Peltier–Seebeck and Thomson effects are reversible and Joule heating is not.
The designers explain:
Thanks to the Seebeck effect, the temperature difference between the surface which touch the skin and the other which is in the ambient air allows to produce electricity that is stocked in a battery. When the user needs to recharge a mobile device, he plugs it into the Dyson Energy through a micro-USB port (universal connector imposed to constructors in 2012) and can have some additional minutes in use.
Firstly, we have tested the Peltier element in its most common use: i.e. the creation of heat and coldness on the same component (Seebeck effect), and we have noticed that there was electricity production. We have met an engineer who allowed us to evolve on our project while explaining us that there was not possible to plug the elements serially. Therefore, we chose to work with only one element. As a result of many calculations, we have validated this technology payoff regarding our concept. For instance, some hours are sufficient to power its cellphone for a dozen minutes of communication.
Designers: Mathieu Servais, Camille Lefer, Clément Faydi & Mickaël Denié

Mind the fact that wrist skin temperature is around 22ºC-25ºC wich can be easily reached during summertime.
You shoul rather use motion of the wrist as power generator.

Using a human’s heat energy to power the machine. That’s straight out of the Matrix.
Scary stuff!
zippyflounder says
now that is a well researched and presented project, BRAVO.

Where we can buy this one ?

Better use motion, or simply sunlight. Using the difference of temperature between skin and air will work, but there’s not a lot of energy there, since most of us spend a lot of time in ambient temperatures that aren’t very far from skin-temperature.

this is truly amazing, nice design, nice concept. Hope to find it soon at the stores! =) would buy it instantly. Perfect for festivals!!
mike says
when you launch? i would buy 3 at a £49.99 pricepoint

Has no one noticed that the e71 does not have a dock on the bottom or any sort of dock?
Or at least the e71x and the unlocked e71 they sell in North America.

I’d like to see the numbers here. I bet it takes a few days of wearing this to get enough battery charge for 5 minutes of cell phone talk time. Probably useless. Pretty design though.

thx

Hi there!
Thanks for your interest in the Dyson Energy concept.
Just wanted to let you know that this isn’t a Dyson product, rather a student entry in the 2009 James Dyson Award.
Thanks again for your interest!

These plans for similar things have been around for a while. They’re a great idea, but why don’t we actualy start making them already, huh?
