Google’s Project Ara Dev Team Tests Blood Oxygen Sensor Module
So, why would health tech drive demand for a modular phone? The pulse oximeter module is a good example: if you have asthma or other lung issues, a pulse ox is probably a familiar friend of yours. It measures the oxygen in your blood and is a good way to determine if you need medical attention for lung function. Having one built right into your phone would be convenient, and would make data tracking easier (for both you and for organizations doing studies). But a pulse oximeter is an unnecessary tool for many of us, and would amount to a waste of resources in an ordinary phone. With a modular phone, the idea is that you’d only add the modules you want to use.
