Project Ara could soon have modular health attachments that would turn it into a small hub for collecting medical data. On stage at the Engadget Expand conference, Project Ara head Paul Eremenko demonstrated on such module in the form of a snap-on pulse oximeter, allowing the phone to measure oxygen saturation levels in the blood.
The smartphone, when it gets released, is expected to have an online store that will sell various different modules directly to consumers, similar to how Google currently runs the Play store for software. It appears that medical and health-related add-ons, like the oximeter, could make it into the store in the future.
