The smart ring with integrated electronics is only slightly bigger than a normal finger ring.

Researchers at Germany's Fraunhofer Institute for Casting, Composite, and Processing Technology (IGCV) have developed a three-dimensionally (3D) printed smart finger ring that potentially could replace house keys, wallets, health insurance cards, and more.

The smart ring contains an integrated radio-frequency identification (RFID) chip that enables it to make purchases, open smart doors, and store medical data, among other things.

Produced using the 3D printing process known as powder bed-based additive manufacturing, the ring is built layer by layer, stopping midstream to place the RFID chip into a cavity in the ring, then continuing.

IGCV's Maximilian Binder said, "Converting the hardware technology to allow electronic components to be integrated during the manufacturing process is unique."
