A team of University of Arizona researchers has developed an ultra-thin wireless device that grows to the surface of bone and could someday help physicians monitor bone health and healing over long periods. The devices, called osseosurface electronics, are described in a paper published Thursday in Nature Communications.

[...] The outer layers of bones shed and renew just like the outer layers of skin. So, if a traditional adhesive was used to attach something to the bone, it would fall off after just a few months. To address this challenge, study co-author and BIO5 Institute member John Szivek -- a professor of orthopedic surgery and biomedical engineering -- developed an adhesive that contains calcium particles with an atomic structure similar to bone cells, which is used as to secure osseosurface electronics to the bone.

It's not for that kind of bone.

    "They also do not need a battery. This is possible using a power casting and communication method called near-field communication, or NFC, which is also used in smartphones for contactless pay."

    So how long until someone will use it for other purposes? For example, as “artificial biometrics”, an identity token that's permanently connected to your bones.

    I just linked the Nature ref on a private chat and was immediately told this kind of in vivo application to mice is strictly forbidden by law in Europe.

    So, for those relevant researchers involved, it's probably best never to travel to Europe in future. Could be interesting consequences to their careers.

    As for social and political consequences, the necessity to actually build tools able to resonance overload and destruct such devices is obvious. It's not difficult at a garage techlevel.

      I'm ignorant and curious. What about this makes the research verboten? It doesn't take a rocket scientist/designer to see that machine human hybrids are on the horizon.

    I seen a youtube video that says that vitamin K2 helps the body absorb calcium out of the blood vessels into the bones. Unlike vitamin K1, vitamin K2 is not found in greens, it's found in fermented vegetables like Kimchi.

      Well, that you saw it on youtube doesn't prove that it's false. But it sure doesn't prove that it's true.

      If it were to be true it would be interesting, but I still wouldn't know what it meant. Perhaps that those who avoid milk and cheese should eat more sauerkraut. Perhaps not, also. Simple explations in biology are almost always wrong.

        "Simple explations in biology are almost always wrong."

        Usually there are multiple competing factors that result in a mixed outcome.

      The ultrathin electronic platform enables direct lamination onto the bone, which provides the opportunity to attach devices permanently to gather information on bone health long term. Because of cell turnover, any glue will exhibit limited lifetime and continuously degrading biointerface quality. A solution to this problem is to directly grow osseosurface devices to the bone using calcium phosphate ceramic (CPC) particles41. For the use in animal subjects, fast adhesion is critical to enable accelerated experimental timelines, which can be accomplished by the addition of transforming growth factor beta 1 (TGF-β1), an osteogenic protein that enables rapid bone bonding to the CPC particles42. We use this scheme to bond CPC particles to the osseosurface electronics using implant-grade epoxy, and subsequently applying TGF-β1 to the CPC particles.
