The shape of the metal tag — a small disk with a hole in the center like a flat washer and various cutouts along the outer edge — determines the frequency of the sound, so each tag can be uniquely identified.“Those unique fingerprints can be used for smart home sensing, or what we call ‘activity recognition,’” said Yibo Fu, a robotics Ph.D. student who led development of the tags with other engineering and computing researchers. Fu said the tags could be attached to faucets to help monitor wa…
