This is a product/company started by a former co-worker of mine. I'll let the video explain more, but they basically worked out how to make carbon fiber flexible for use in hinge-like applications. Right now, they've used their technology for wallets and phone cases, but I feel like the technology has a decent amount of upside. Anyways, check out the video and show some support! kickstarter site.
