For our third Macktion at CES 2015 video we see the master videographer showing off Blue Spark Technologies' interesting new flexible battery technology. These batteries are actually printed using a technology that is similar to "screen-printing" which is the way T-Shirts are printed. The batteries are currently used in mostly custom products like RFID tags, mobile sensors, mobile electronic labels, and even wearables, etc. One specific example they gave was a mobile electronic band-aid for the medical industry that can transmit your body temperature and other stats to help medical techs and nurses. They are even talking about adding lights and sound to store products like a cereal or cookie box. Very cool!
