Researchers at the University of Arizona (USA) have developed a tiny wireless device that permanently bonds to bone and is capable of transmitting data externally.
This breakthrough could allow doctors to monitor patients’ bone health in real-time or track recovery levels after injuries.
The device can be implanted in individuals with conditions such as osteoporosis.
The new invention, referred to by the research team as the “bone surface device,” contains a series of sensors that are inserted into an area the size of a coin and as thin as a sheet of paper. These sensors can transmit data about the bone to a smartphone or other devices.
Notably, the device does not require a battery to operate. Instead, power can be transmitted externally using Near Field Communication (NFC).
To ensure the device remains attached to the bone long-term, the research team developed an adhesive that contains calcium phosphate particles, allowing bone to actually grow onto it. This enables the device to bond permanently with the bone. The devices are designed to be thin enough to avoid discomfort for users when muscles move.
The research team expresses hope that such devices could be implanted in individuals with conditions like osteoporosis. This would enable long-term monitoring of patients’ bone health. Additionally, the device could assist in recovery after patients experience fractures, allowing doctors to track how bones heal.
Mr. Philipp Gutruf, a co-author of the study, stated: “Being able to monitor the health of the musculoskeletal system is extremely important. With this interface, we essentially have a computer on the bone.
This technological platform allows us to create investigative tools for scientists. Thus, we can explore how the musculoskeletal system functions while also utilizing the collected information for recovery and therapy.”
The research team has tested this device on animals, with results showing that the device can be implanted in both large and small animal models. Data from the device can be read using a smartphone.
However, according to scientists, this research is still in its early stages. It will take a long time for the team to bring this device into application. The study has been published in the journal Nature Communications.
