The ELectronic FOod “ELFO” project funded by the European Research Council ERC consolidator grant will provide the foundations of a new enabling technology for edible electronic systems. The platform will find applications in electronic tags for food monitoring, serving public health and providing at the same time a very powerful tool against counterfeiting. Moreover, the implementation of a smart edible pill will supply gastrointestinal disease prevention, diagnosis, and therapy. These systems will be unperceivable and mass produced mainly with mask-less, printing and direct-writing methods. Besides being completely safe for ingestion, such devices will also be perceived as “smart food”, favoring public acceptance.
