“Smart Ink” Microbatteries
November 25, 2014 | Terry Sharrer
Battery size has a limiting effect on a number of implantable and wearable devices. To address this, a Harvard lab has used 3-D printing to create microbatteries 1 mm square. Of course, the trick in this is developing smart inks, which in this case are made from lithium-titanium oxide. The ink is printed on a glass substrate with anode and cathode terminals. See the video in this piece of the manufacturing process. MORE WITH VIDEO
