2. One day even lamp posts won’t be dumb: As Chris Harrison sees it, the world is full of surfaces, so why are we spending so much time touching little screens or tapping on cramped keyboards. Harrison, a researcher at Carnegie-Mellon University, has been a leader in finding ways to turn everyday objects–a couch, a doorknob, a glass of water–into interactive devices. His approach is to use the natural conductivity of objects–or attach electrodes to those that aren’t–and connect them to a controller that responds to different types of signals. A couch, for instance, could be wired to turn on the TV if someone sits on it in a certain spot. Or you could turn off all the lights in your place by twisting the doorknob or tapping on a table. Almost anything with a surface could be connected to a computer and allow you to make things happen with simple gestures or touches.
3. Finally, a tatt for Grandma: There’s no questions that health tech is booming–although that’s not always a good thing considering that health apps don’t always live up to their hype. But Nanshu Lu, an engineering professor at the University of Texas, has created a product that could have a huge impact on how we monitor what’s going on inside our bodies. She has refined what are known as “epidermal electronics,” but basically they’re electronic tattoos that can track your vital signs, including your temperature, heart beat and brain and muscle activity. Lu has managed to develop ultra-thin, water-soluble silicon patches that contain tiny sensors and can actually bond with skin. No adhesives necessary. They last through showers and exercise, never losing their ability to gather your most personal data. The hope is that one day her tattoos will be able to treat diseases.
