These low cost monitoring solutions will certainly attract attention - but how compatible are they with food? Can the battery and circuit be cut with a knife and safely ingested with the food? If not, how will the packaging be designed to ensure that the monitor is removed before the food is prepared?
I can tell that the partnership between the few companies would be good because they would be collaborating in a way that brings out the best in their collective expertise. I think we can look forward to interesting new functions for plastic films, such as plastic films that can tell us the expiry of foods.
