No, this is not a late April Fool's joke or a prank by Apple. According to a new patent filing submitted by Apple, future devices such as the iPhone and Apple Watches may have “smell recognition capabilities”.

The company has been trying to detect air pollution levels and other harmful particles with tiny sensors that could be embedded into future devices. The new patent also shows that Apple could use other multiple sensors that will be able to detect body odour, rotten food and maybe sugar levels. 

The patent is called “System and Methods for Environment Sensing” and it explains a system where sensors could be used with an “artificial intelligence engineer to recognize smells associated with certain chemicals.” The patent also shows how an ionic liquid sensor would be tuned to specific ranges and enclosed into an SoC. 

The system would have an in-built that will be able to raise temperatures on the ionic fluid in order to reverse any chemical reactions. Patents show that Apple is going to add the smelling technology to the Apple Watch and the iPhone.

Previous patents show that Apple wants to give owners of their devices to access air quality data. This would be highly useful especially in areas where pollution levels are off the roof. The previous patent by Apple shows that Apple wants to monitor the ozone, carbon monoxide and other harmful gases.

For diabetic patients, it would be awesome to detect blood sugar levels without the need for withdrawing blood. This would be a game changer for people who want to get rid of the tedious process. As for detecting body odour, that would help everyone from being embarrassed for sure. 

Being a patent, we cannot expect to see these sensors and features on a new iPhone anytime soon. In fact, there's a good chance we may never get to see it. Having said that, if this patent comes to fruition, we can all be excited about the future.
