  9. Project Ara: A Modular Smartphone Using Electro-Permanent Magnets

    Project Ara: A Modular Smartphone Using Electro-Permanent Magnets
    One of the hot topics this week is Project Ara, a modular smartphone that can be customized and updated using electro-permanent magnets. If you haven’t heard about the project yet, it could entirely change the way we update our smartphones. For instance, instead of just buying a new phone and tossing out your old one every few years, Project Ara phone’s modular units will allow owners to simply replace and upgrade parts as needed. The smartphone fosters user customization and could possibly reduce the estimated 20 to 50 million tons of environmental e-waste generated each year. Continue reading →
