• L’Oreal’s UV Sense is a tiny wearable sensor that attaches to your thumbnail. No batteries required here – it connects to your iPhone or Android smartphone via NFC to give you gathered data on how much sun exposure you’re getting.

• The Arable $500 sensor is game changer for farmers. It tracks over 40 metrics, giving farmers insight into the quality and progress of the foods that will end up in the grocery store.

Equipped with cellular modem, it can transmit timely messages or warn of impending inclement weather.

All three devices feature a new, always-on fingerprint sensor that presumably, would stop working if someone picked up your phone off a table. The phones have a premiere look with narrow bezels.

This a good news because this technology is much more secure and safe. The idea is to populate your home or office with LiFi lights. Airline cabins for example could beam streaming data like movies from lights over every passenger seat. Even a Local Area Network can be set up for a group of users through a bunch of LED LiFi equipped lights.
