** Some smartphones include a FLIR sensor for infrared photography. Many more can accept an external aftermarket module, though this is less convenient.

** Some smartphones have extremely specific sensors. The 2019 LG G8 included a infrared sensor system to map the veins of a hand via hemoglobin detection, as The Verge reports [https://www.theverge.com/circuitbreaker/2019/2/24/18235249/lg-g8-z-camera-hand-id-palm-scanner-ir-infrared-veins-unlock-mwc-2019 here].

** Simple smartphone sensors used in conjunction with other systems can often detect more than one would expect. For example, a camera used in conjunction with a machine learning system can identify many plants.

* Smartwatches frequently include a limited suite of sensors for the purpose of collecting and logging biometric information over the course of a day.

** Smartwatch sensors can include GPS, microphones, accelerometers, underwater depth gauges, barometric altimeters, compass, gyroscopes, cameras, thermometers, electrocardiogram, bioelectrical impedance analysis, continuous pulse oximeter, and more.

** By using these sensors and other techniques, it is possible to track things like workout metrics, REM sleep, period tracking, etc. It is also possible to automatically call for help if a fall or crash is detected and the user does not respond to a follow up prompt.

* The Google Android platform had a groundbreaking app called "Google Goggles" which is a step in that direction. It uses the camera to analyze photos and display information on book covers, artwork, landmarks, or restaurants. Such features are now common in augmented reality apps, and are often simply built into phone operating systems.

* A tricorder app was downloadable for Android that used built in phone sensors. [http://mobile.slashdot.org/story/11/09/02/2229200/Android-Tricorder-Killed-By-CBS CBS killed it].

* Hyperspectral sensors allow there to be so much information in an image that a computer can determine exactly what materials everything in it is made of.
