Researchers built an ultra-thin wireless sensor, designed to monitor bone health over long periods of time.
Battery-free device is intended to measure a variety of physiological parameters.
The device is affixed to the bone surface using a calcium adhesive.
Encourages the bone to grow and fuse with the device surface for long-term implantation.
Technology could also help with clinical decisions, such as when to remove plates or screws from a bone.
Dr. David Margolis, researcher involved in the study says "...with the goal of accelerating rehabilitation and maximizing function after traumatic injuries".
Unique adhesive consisting of calcium particles helps the device to adhere to the bone surface.
Bone thinks the device is part of it, and grows to the sensor itself.
Allows it to form a permanent bond to the bone and take measurements over long periods of time.
