Tech Tuesday: Facial Recognition blocking glasses & tiny 3d printable batteries

This week on News 1130 Radio in Vancouver, I talked about these items:

• Privacy visor glasses jam facial recognition systems to protect your privacy: Currently being developed at Japan’s National Institute of Informatics, these glasses have a number of near-infrared LEDs embedded in them that are invisible to the human eye but blinding to facial recognition cameras. Still in the prototype stage, these could one day be available to those that want to protect their privacy when in public.
• Tiny 3d printed batteries: Researchers at Harvard and the University of Illinois have developed a way to create 3d printed lithium batteries the size of a grain of sand. Until now, powering medical implants, nanorobots and other items from science fiction lacked a method of being powered. This new technology should dust off a bunch of these ideas now that they can create the power supply in the same scale as the technology required.
