We’re already seeing blood-sugar sensors for diabetics that plug into phones, sensors for environmental pollution, and I think we will rapidly see the growth of body-oriented sensors as part of the “quantified self” movement. Remote sensing of the chemical composition of the blood and even simple imaging devices will contribute to the growth of medicine and again, smartphones plus sensors in the body and sensors in the environment will lead to a new medium unlike smartphones as we know them today.
