Connected devices can now share position information, even in noisy, GPS-denied areas.

RFID-based devices work in indoor and outdoor lighting conditions, and communicate at greater distances.

Submerged system uses the vibration of “piezoelectric” materials to generate power and send and receive data.

Along with studying theory, "it's also important to me that the work we are doing will help to solve real-world problems,” says LIDS student Omer Tanovic.

In some cases, radio frequency signals may be more useful for caregivers than cameras or other data-collection methods.

System uses RFID tags to home in on targets; could benefit robotic manufacturing, collaborative drones, and other applications.

Device made from flexible, inexpensive materials could power large-area electronics, wearables, medical devices, and more.

Electronic pill can relay diagnostic information or release drugs in response to smartphone commands.

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

System that automatically identifies people moving around indoors could enable self-adjusting homes.
