But many in the cardiology field seem hopeful that similar technology will help improve individualized medical care in the near future. As Krum concluded in his essay: "We are only at the beginning of this revolution in patient monitoring."
The sensor technology also has the potential to improve medical treatment for other common conditions. Similar MEMS sensors are already keeping tabs on stents implanted to treat aortic aneurysms. The sensors can also track healing in bone fractures and swelling in the brain after an accident or illness, Yadav notes, and could be useful in other conditions, such as liver disease or urological troubles.
Abraham envisions a future where implanted sensors could communicate with other internal devices, such as pacemakers, permitting fine-tuned calibration in real-time as a person's condition changes day to day, hour to hour, beat to beat.
