The first digestible microchip was approved this week by the FDA . I saw this article, “FDA Approves First-Ever Digestible Microchip ”
Proteus Digital Health is the creator of this device.
It can safely be embedded into a number of pharmaceuticals
The microchip is a tiny square of silicone, no bigger than a grain of sand.
Stomach acid activates the magnesium and copper in the chip to produce slight voltage. The signals are transmitted to a wearable patch and from there to a cell phone for tracking items like heart rate and rest patterns.
