Different skin tones need different amounts of UV light to activate vitamin D in the skin.
UV ratings indicate risk of skin damage – but they're based on pale skin. New wrist bands designed for six different tones of skin provide a more personalised way to track safe UV exposure.
Imagine using synthetic DNA as a sensor recording device.
One way to make sensors small is to make them out of something that's incredibly small in the first place, such as DNA.
Autonomous vehicles are information-rich platforms thanks to the range of sensors on board that track, monitor and measure everything.
Sensors that monitor everything a self-driving vehicle does can help determine who is responsible in the case of an accident – the manufacturer, the service centre or the vehicle owner.
Fitness trackers report their location and map the Burning Man festival in the Nevada desert.

It's not just fitness trackers – mobile phones can reveal users' whereabouts too, even with location tracking turned off.
Drones being used to find survivors after an earthquake in Ecuador in 2016.
Stand by for drones, robots and sensors to the rescue.
Is this an impostor trying to break into your phone with his voice?
You can log in to your smartphone by talking to it. Current security systems don't protect enough against imitators. The best way to ensure voice authentication is secure is to start with the sound.
Dr. Kofi Amegah of the University of Cape Coast, Ghana, installing a small air sensing unit built by the University of Massachusetts.
Citizens and activists are using cheap off-the-shelf sensors to collect their own data on air pollution. It's a promising trend, but these devices have serious technical limitations.
Connecting cities should serve all citizens, not just a few.

Design will make the difference between smart city projects offering great promise or actually reinforcing or even widening the existing gaps in unequal ways their cities serve residents.
A hydro-responsive thread can be used with sensors to monitor body functions.

Flexible, easy to make, inexpensive, stretchable and simple to coat with nanomaterials, threads are also very commonly used by doctors already.
Microsoft Kinect's cheap sensors could create low-cost 3D computer models of crime scenes.
Humidity levels can mean life or death for insects.
Detecting drier or wetter conditions is crucial for insect survival. We've long known they can do this – now researchers have discovered the genetic and neural basis for their humidity-sensing system.
These backpacked pigeons are patrolling London’s skies.

This low-cost way of monitoring air quality is appealing, but there needs to be acknowledgement of their weaknesses as well as strengths.
Still a few kinks to be worked out.
We can already track plenty of body data, but to really make a difference, wearables need to consistently collect clinically valuable information that can be used to improve health.
