Tiny microchips and nanotech are in vogue.

First we have this tiny camera the size of a grain of rice. Someone could swallow this and it could view a person’s stomach. But it would also need a power pack, case and transmitter. https://petapixel.com/2011/03/10/researchers-unveil-worlds-smallest-camera-the-size-of-a-grain-of-salt/

Then we have a smart dust chip.

Then we have quantum dots, which can store information.

Quantum dots can also send chemicals to specific organs, including the brain.

And some more nanotech for drug delivery is in the works.

And an implantable chip that can detect COVID-19. How can that be when it’s a new virus and tests can take years to develop, and there’s no gold standard for this test at all?
