What New Technology Would Be A Good Topic For My Ninth Grade Technology Class?

It has to be an “emerging technology” meaning new. It can’t be more than three years old. As in, a phone is not an emerging technology. The Iphone is. I’d like something with enough information to do an oral report and written report on it. Currently on my list, meaning don’t suggest them, are projectable keyboards, the aptera, the iphone, and a computer currently being devloped with microsoft that “reads brain waves”. Thanks!
