To save power, a cheap new timer can tell smart sensors when to wake up—no batteries required.

Scientists are working toward creating a sensor that would evaluate how much a person trusts an intelligent machine.

"Drones can fly for maybe 10 or 20 minutes before they need to charge again, whereas our bees can collect data for hours."

This lays the groundwork for developing active, form-fitting sensors or devices to use in telecommunication, biosensing, and other applications.

"Knowing more about how these tiny movements work might offer new design strategies for our smart devices to sense the world."

The electronic glove imitates the way layers of human skin work together to give our hands their extraordinary sensitivity.

The sensor film will be able to tell engineers exactly where stress or strain is affecting structures like bridges, airplane bodies, or pipelines.

Simple, scalable wireless system uses the RFID tags on billions of products to sense contamination.

Technique from MIT could lead to tiny, self-powered devices for environmental, industrial, or medical monitoring.
