Three Futuristic Health Sensors That Could Save Lives

Entrepreneurs at Fortune’s Brainstorm Health conference in San Diego on Wednesday showed off what they believe is the solution to lowering medical costs and bringing better care to the developing world.

They demonstrated a range of devices: a mobile ultrasound machine, a handheld air sensor, and a patient identification necklace. That technology all shared some commonalities including low-cost sensors, wireless connections, and data stored in the cloud.
