Cutting Edge Vision: Metal Embedded Optics for Smart Knives


Credits: Amit Zoran, NanWei Gong, Roy Shilkrot, Shuo Yan, Pattie Maes

Cutting Edge Vision presents a novel technique for embedding optic fibers into a metal blade to sense objects that the knife is cutting. In particular, it presents a design for a kitchen knife with fiber optics between the edge of the blade and the handle, with a skin-color sensor that overcomes the complex conditions in the kitchen. Hoping this design will lead to future work on minimizing cooking injuries, our handheld device also includes a simple finger-protection mechanism in the form of a retracting blade. We present our novel hardware design, an initial study of imaging capabilities, and a discussion of future directions.
