With a plug-and-play jewelry tech maker kit, jewelry can now shine colorful lights, give you a nudge or help you connect with people at the other end of the world. China's smart jewelry brand Totwoo launched its smart "Totwoo love" kit with US fashion tech company 360Fashion Network at the SAP Net-Gen Space at Hudson Yards in New York on Wednesday evening. The wearable tech DIY kit enables fashion and jewelry designers to create pieces of smart jewelry using Totwoo Inside smart core 2.0 without the need to code or solder. A tap or two makes a necklace or bracelet embedded with smart core work as a fitness tracker or a reminder of an incoming call. The kit includes smart core, 3D files, a 3D printed base and a charger.
