Stretchable optical waveguides provide viable sensing solutions for soft robots. So far, basic single layer or core-cladding waveguides have been developed using various manufacturing methods. Extending their structure to increase sensing functionality has been mostly unexplored. This study investigates a waveguide design featuring a semi-divided core cross section guiding the light from one light source to two light outputs. With optical ray tracing simulations using COMSOL, we verify the design’s two main working principles that enable two-degree-of-freedom sensing in various strain modes.
