Early demonstrations of edible devices to detect bleeding. (A) This device includes a circuit that contains a sodium perborate window in close proximity to a thermistor. (B) In the presence of blood, an exothermic chemical reaction is transduced into a thermal signature that can be relayed to an external receiver. Reprinted by permission from Springer Nature.

Edible sensors for bleeding detection that integrate engineered microbial sensing elements. E. coli bacteria can be genetically engineered into a modular sensing element for bio-integrated ingestible sensors. (A) Devices house E. coli in on-board reservoirs that are programmed to respond to extracellular blood via heme by generating (B) a dose-dependent photoluminescent output. (C,D) This optical signature is quantified by an on-board low-power luminometer that then transmits the data to an external receiver. This device can detect bleeding in porcine subjects in less than 2 h after deployment. (E) The modular nature of the device can also detect the presence of other biomolecules that may be important for gut health. *, P<0.05, **, P<0.01, Student’s t-test. From Mimee et al. (5).
