New research shows passive sensing without being connected to a power source can be done at little cost without specialized equipment.

RFID tags are commonly embedded in products like clothing or library books for tracking inventory or in contactless transit fare payment cards.

The future of passive data-based sensors can do both passive and real-time data collection.

By embedding RFID sensors in shoe soles, UC San Diego athletes can measure jumping force.

RFID tags can be placed in parking garages to measure occupancy and map parking spaces.

"We're at the cusp of a revolution where new sensors will be collecting the data that will power the next generation of AI ," says Nagarjun Bhat .
