This edible sensor could reveal what our gut microbes are up to

Wouldn’t it be nice if our microbiomes could serve up diet advice—some science-based assurance that our food and medicines act in harmony with our resident microbes to keep us healthy? For that to happen, scientists will need to better understand how the interaction between food and microbes affects the chemical composition of our guts. Now, a team of researchers has developed an edible device that passes through the digestive tract, measuring concentrations of intestinal gases along the way.
