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.
