Smart Device Identification of Potsherds and Gemstones with Radiofrequency-Induced Harmonics Vibrations

In materials like potsherds and precious or semiprecious gemstones, radiofrequencies can cause specific vibrational signatures. We previously described a method for identifying pottery shards using ultrasound stimulation and vibrational characteristics. The experimental technique for extracting such signatures from ceramic shards and precious gems using radiofrequency stimulation is now detailed. The technique offers a possible method of on-site substance recognition by extracting vibrational signatures quickly and cheaply and comparing them to a database library.
