In yet another case of biomimicry providing a platform for engineering innovation, researchers are testing a “smart pill” the could inflate inside the stomach — similar to the way a puffer fish puffs up. The pill might one day be used to transport tiny sensors in the body to areas where they could help detect ulcers, cancers and other signs of disease. Fulton Schools Professor Hanqing Jiang, whose research includes ingestible electronics (but who is not involved in the smart pill puffer fish-mimicry project) says the work may produce an important advance in the development of biomarkers to monitor human health.
