Apple's new health patent: you can use iPhone and Apple Watch to detect your breathing.

CTOnews.com August 25 news, according to the United States Trademark and Patent Office (USPTO) published list, Apple obtained a health-related technology patent, can use iPhone, Apple Watch to analyze the wearer's respiratory system.

Apple says people with chronic obstructive pulmonary disease (COPD), asthma or other airway-related conditions may experience reduced airflow (also known as "airway obstruction") when breathing, resulting in breathing difficulties.

Spirometry is currently the most common breath test, but it is less accurate and repeatable than expected and often requires assistance and supervision from a clinician.

Apple's patent outlines a system for measuring a user's breathing function, which can detect the breathing movements of the user's torso through an optical sensing unit on the iPhone and measure breathing through a corresponding algorithm.

Another way is to modify the Apple Watch by attaching it to the wearer's chest with a special sticker and then monitoring the wearer's breathing characteristics. CTOnews.com attaches patent illustrations as follows:
