Similar to having an RFID implanted in the body, this device will be like a personal doctor that you can carry everywhere you go. Dr. David Loftus, the inventor of the technology, works at the Space of Biosciences Division at NASA which provides healthcare research for crews in outerspace. One of the main threats for astronauts in space is the acute exposure to high levels of solar radiation, which can damage bone marrow and destroy the immune system. Here is where the NASA Biocapsule takes action: it can be filled with cells that sense the increased levels of radiation and automatically disperse medicine to help the body compensate.
The capsule will be able to deliver doses over a long period of time. It is extremely resilient, inert, and bio-compatible. The capsules' porous walls allow medication to pass through but retains the cells in the same location. Once implanted, the Biocapsule will stay in the body, stable and unnoticed, until it is removed by a doctor back on Earth. This might be a breakthrough in medicine since they are beginning to look into using this technology as a permanent implantation to provide insulin and treat diabetic patients in the future.
