Naomi Kihzner is an Israeli industrial designer, and her Energy Addicts jewellery is a statement on our use of energy, and a discussion about “about how far will we go to in order to ‘feed’ our addiction in the world of declining resources.” (It was also her final school design project.)

The jewellery operates on the wearer’s blood supply (to turn wheels and cogs inside) and is lightly embedded in the skin. It wouldn’t be the first time that jewellery was used for a specific purpose unrelated to adornment. I know it isn’t meant to be used to create meaningful energy, and is a statement more than anything, but it’s a very intriguing concept. I could see “jewellery” being used as a device to deliver medication or monitor vital signs in this way…
