InfraStructs: Fabricating Information Inside Physical Objects for Imaging in the Terahertz Region

My Note: I just came across this on the web today. I had never heard of InfraStructs, before, but it's obviously a new arena for THz applications.

InfraStructs are material-based tags that embed information inside digitally fabricated objects for imaging in the Terahertz region. Terahertz imaging can safely penetrate many common materials, opening up new possibilities for encoding hidden information as part of the fabrication process.
