microchipThe 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.
