An optical sensor that can detect individual molecules promises early detection of diseases and environmental contamination.
Driverless vehicles rely heavily on sensors to navigate the world. They're vulnerable to attack if bad actors trick them into 'seeing' things that aren't there, potentially leading to deadly crashes.
Advancements in data analytics can prevent food wastage and save farmers from significant losses along the fresh produce value chain.
Brain functions integrate and compress multiple components of an experience, including sight and smell – which simply can't be handled in the way computers sense, process and store data.
Nearly half of patients with congestive heart failure who are hospitalized and then discharged end up back in the hospital within 90 days. Could a toilet seat help prevent this from occurring?
During a military mission, whether in peace or in war, the inability to identify an object within an area of operation represents a significant problem.
A pilot and researcher knows that airplanes are full of sensors – and finds a way onboard computers can use the data to detect equipment failure and tell pilots what's a real emergency and what's not.
Globalization is making it harder to identify and trace outbreaks of foodborne illness. Technology can help, but consumers may also have to rethink their food choices.
From offshore oil and gas to the homes of people with disabilities, this is emerging as one of the most exciting areas of tech.
One-third of roads in the U.S. are unpaved; plenty more have faded or obscured road markings. Today's self-driving vehicles can't go on them, and will need new algorithms to handle those conditions.
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.
One way to make sensors small is to make them out of something that's incredibly small in the first place, such as DNA.
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.
It's not just fitness trackers – mobile phones can reveal users' whereabouts too, even with location tracking turned off.
Stand by for drones, robots and sensors to the rescue.
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.
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.
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.
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.
