I'm not sure what to think of this - whether it is a brilliant adaptation of technology, or an example of technology running amok. A company has developed metal bolts with indicators that change color depending on how much the bolt has been tightened. Initially created for conventional construction, these bolts are thought to eventually be coming to a neurosurgeon or orthopod near you.
One would think that the degree of tightening could be controlled just as well with a torque wrench, but perhaps there are situations where bolt tightness changes after the initial set, and these indicators would then give a visual signal that loosening has occurred. Curious.
MedGadget has more technical details, which seem to obfuscate more than they clarify.
