Paper Abstract

In this article we present experimental demonstrations of a self-writing polymer waveguide strain sensor that can selfrepair after failure. The original sensor is fabricated between two multi-mode optical fibers by ultraviolet (UV) lightwaves in the photopolymerizable resin system via a self-writing process. After the original sensor fails, the repaired sensor is grown from the existing waveguide to bridge the gap between the two optical fibers. Multiple self-repairs of a single sensor were demonstrated. When the sensor was packaged within a polyimide capillary, the cyclic response showed almost no hysteresis and the response over the entire strain range was monotonic.
