The Droplet project aims to redesigned the electric toothbrush to be just as easy to use as a non-electric one AND do as little harm as possible to the environment! The design uses a vibration motor similar to ones used in smartphones. This drastically reduced the overall size and minimized the part that needs replacement. Now, users no longer have to replace the entire head. This further minimizes waste. When it comes time to cycle out the cleaning head, simply interchange a smaller tip made of silicon that’s easier to recycle. Designer: Mian Wei
