In the future, you will be able to get implants that can give you info about oxygen, glucose, and other body chemistries. Take Profusa’s injectable body sensors for instance. They become one with your body and stream data to mobile phones and to the cloud. Here is what they are about:
The team at Profusa is developing a family of tiny biosensors composed of a tissue-like hydrogel, similar to a soft contact lens, that are painlessly placed under the skin with a single injection. Rather than being isolated from the body, the biosensors work fully integrated within the body’s tissue — without any metal device or electronics […] The Lumee Oxygen Platform, the first medical application of the biosensor technology, was approved for sale last year in Europe, and is helping wound-healing specialists track oxygen in the lower extremities of patients undergoing treatment for chronic limb ischemia
Each biosensor is a flexible fiber about 5mm long and half a milometer wide. In the future, these sensors can be used to monitor glucose, lactate, carbon dioxide, and other molecules.
