This document discusses digital jewelry, which embeds computing components like microphones, displays, and antennas into jewelry items like necklaces, bracelets, and rings. It describes a prototype from IBM that divides cell phone functions between multiple jewelry pieces connected by Bluetooth. Components are embedded in necklaces to hold microphones, ear rings to act as speakers, rings that flash notifications, and bracelets with small screens. While offering wireless convenience, digital jewelry still faces challenges with small displays, potential health issues, waterproofing, and costs.
