I have recorded and included a video of trialing the NFC eink / epaper display for potential use under skin. As stated before the image quality is drastically decreased under a material as transparent as parchment paper and it is doubtful that any meaningful display would show through skin, or any thicker material.
For other uses, the use of the eink’s bistability allowing the image to remain indefinitely without the use of battery. The display is quickly and easily refreshed with an NFC enabled device and is pretty neat. I’m sure I’ll be able to find a cool use for it but not as an implant haha.
