Advantages of biological EE:

• Devices can be deployed without the need of a skilled healthcare practitioner or invasion surgery.
  • They don't need to be sterilized, implants can have a very different immunological response.
• Ingestible devices have a lot more latitude in terms of the kinds of flexibility in materials.
• Materials used for EE could be degradable so if anything would go wrong the material would breakdown.

Using melanin with some electromechanical processing to create a battery material that can supply power to ingestible electronics.

Human as a piece of modular code.

With edible electronics you can do many of the same things that you can perform with implants. For example - sensing functions.
