Naomi Kizhner's jewellery collection harvests
energy from the human body


Industrial designer Naomi Kizhner has developed a concept for an invasive jewellery collection that converts kinetic energy from the body's involuntary movements into electricity (+ slideshow).

Naomi Kizhner designed the Energy Addicts accessories in response to the world's impending energy crisis, looking for an existing energy source that is yet to be tapped in to.

"It interested me to imagine what would the world be like once it has experienced a steep decline in energy resources and how we will feed our energy addiction," Kizhner told Dezeen. "There are lots of developments of renewable energy resources, but the human body is a natural resource for energy that is constantly renewed, as long as we are alive."

"I wanted to explore the post-humanistic approach that sees the human body as a resource," she added.

The pieces would be embedded into the surface of the skin to capture the energy of subconscious movements, such as the flow of blood through the veins and blinking, transforming it into a useable energy resource.

Made of gold and 3D-printed biopolymer, each design in the collection would be worn on different parts of the body to harvest energy from specific physiological functions.

Spikes at each end of the Blood Bridge would insert into a vein in two places on the lower arm, redirecting the blood past a wheel inside the casing. The blood flow would then turn the wheel to create movement that the device could convert into electricity.

The E-pulse Conductor would harvest energy directly from the electric pulses sent by the neurological system through the wearer's spine.

Sat on the bridge of the nose and across the eyelids, the Blinker would transform the energy generated during the opening and closing of the eyes into electricity.

"Technologically we are not too far away from these ideas becoming a reality," said Kizhner. "But practically speaking, will we be willing to sacrifice our bodies in order to produce more energy? My intention is to provoke a discussion."

"I hope that the project will make people think about the possibility that this could be their future, and make them think about whether it is the future they want or whether we can do something different today to avoid it."

Energy Addicts was created as part of Naomi Kizhner’s graduation project for her BA in Industrial Design at Jerusalem's Hadassah College.

    The image of the piece in her arm is the one that’s prompted the most visceral reactions in the office. Once you get beyond that initial response, it’s an interesting idea.

    • My first reaction was, my goddess, they’re glamourising self harm. Isn’t there an element of that? Undoubtedly they are beautiful objects which compliment the body. We are on the turning point of a technological revolution. How soon before it is common to see people wearing and subtly integrating with technology?

      This could give them senses, intelligence and information or replenishing energy. Let’s hope that the devices of the future look as good as these.

        “Undoubtedly they are beautiful objects which compliment the body.”

        Yeeeaaah….. no.

        Only if you enjoy steampunk.

        “How soon before it is common to see people wearing and subtly integrating with technology?”

        Don’t know, how soon will my promised hover-car become available?

        • Joey Aleman

          Just wanted to say that we are already wearing and subtly integrating with technology. Maybe not the majority, but it is happening.

        • As I was saying a year ago… Google glasses and other wearable devices are becoming more common. But I still crave technology that sort of integrates with the central nervous system… :-)

          I had to Google steampunk – no, not really into that sort of thing.

          Hover cars have been in prototype stage for a very long time. It’d be nice to see Star Wars-type hover craft any day now… but it seems that a lot of the emphasis on transport these days, goes into developing surveillance and traffic control systems like vehicle-to-vehicle communications.

    The human power-plant. Imagine the technological marvels we could graft to our bodies if we could power them ourselves. Post-humanism indeed!
    The products are beautiful, even sensual in a frightful kind of way.
    I would love to see the products expanded to include not only kinetics, but also “electrochemistry”.

  • SebH

    “…the human body as a resource”? That reminds me of Alien. I am not so sure about all this.

  • eww

    I think it’s very freaky.

  • Alan

    It’s quite an exciting prospect. The gadgets of the future will only be limited by our imagination.

  • ana c

    Oh, yes please. Two of those!

  • Jordi Panzram

    Why are some of these pictures straight out of a body horror movie? The one showing just the arm is a perfect example; some techno parasite sucking the blood out of a clueless woman. This is David Cronenberg-type jewelry.

  • j

    Ugly pieces and unoriginal. Lame idea.

  • Ralph Kent

    I’m the first to confess that I don’t know much about this stuff, but I have listened to the Black Eyed Peas and I now know this: “ENERGY NEVER` DIES”. Will.I.Am’s lyrics suggest to me that if you insert a hamster wheel into your arm, which is spun by the blood flow of your veins or arteries, then that energy has been transformed from your body’s energy into kinetic energy. To compensate for the lost energy to make your blood circulate, you’ll eat a bit more food.

    The words ‘Zero Sum Game’ spring to mind.

    But hey, as I said, what do I know. This might for once be a product designer who has actually deeply researched the subject, unlike the majority of these sort of projects where the author has cursorily read a Wikipedia entry and then goes off on one, convinced they are now leading experts in that field.

    We will use our own blood to power the machines, and you find it “an interesting idea”, “give them senses”, “marvels”. Nothing else to say. Everything for profit! You sold your soul! What’s left in you? I thought humans could think about the consequences!

  • Asher Lucas

    Ride a f***ing bike with a dynamo attached for 30 minutes a day. Get exercise and generate more energy than these ridiculous shock-pieces would in a week.

  • Avelino

    You’re kidding? Insert things in your veins and leave it there? I can imagine some reasons why you should not do such a thing: infections; high blood pressure; hepatitis; your red blood cells are extremely fragile; people with anaemia or diabetes, death…

  • KD

    Fascinating idea and project! I think the artefacts are beautiful and well crafted too!

  • Linda

    I’m sorry, but this is disgusting and totally insane.

  • Ronin_84

    Uhhhh, yeah…. thanks, but I think I will pass on that. Permanent pain from being repeatedly poked by needles, or having that break off inside my skin, is not my idea of a fun time.

    Have you ever had an intravenous tube in your arm? Having something stuck in your arm becomes uncomfortable, especially for long periods of time.

    Call me when you couple that with a permanent morphine drip. The way I see it: that’s the only way anyone will buy into this.

  • William Villarreal

    When and where can I get one.

    It’s an interesting concept but also potentially quite dangerous! Especially the venous wheel. Blood naturally clots and any device bypassing blood outside the body (extracorporeally) would need a constant source of anti-coagulation.

    The blood would naturally deposit clotting factors around the device and then re-deposit them back in to the vessel once large enough, leading to all the potential complications of venous thrombosis such as stroke, heart attacks or cell death. Concept good! Design needs a bit of work.

    Pornhub are developing along similar lines:

  • Wandering In

    I won’t comment on the fashion side of things but I’d say whipping some people to make them run on treads would be a more efficient method of generating energy.
