A flexible, free-standing terahertz (THz) camera patch developed by researchers at Japan's Tokyo Institute of Technology (Tokyo Tech) and RIKEN can film irregularly shaped objects more easily than traditional bulky and rigid THz cameras.
The THz sensor array can be used to image blind ends of objects with diverse shapes.
The researchers used a vacuum to pass a carbon nanotube solution through a polyimide film with laser-induced slits and a membrane filter, and evaporated metal electrodes over the patterned polyimide film to create a camera patch sheet with multiple cameras.
Smaller portable and wearable sensors can be made by cutting the patch sheet.
Tokyo Tech's Yukio Kawano said, "Our patch camera can be easily set up for imaging of large and unmovable objects. The unique [two-dimensional] THz camera patch can ease restrictions pertaining to the shapes and locations of objects, contributing significantly to non-destructive monitoring sensor networks."
