摘要
En 中文
In this work, we have demonstrated a specklegram proprioceptive sensor capable of sensing large tensile strains based on a single silica multimode fiber (MMF) embedded in a soft silicone pad. Taking advantage of the rich information contained in the output speckle patterns from the MMF and a convolutional neural network (CNN)-based regression demodulation algorithm, the sensor shows an extended strain sensing range of up to 10%, and the root-mean-squared error (RMSE) is determined to be less than 0.05%. In addition, by integrating with a classification model, the sensor is also able to distinguish the direction of the applied tensile strains, i.e., the axial or the longitudinal directions, with an accuracy of 100%. The proposed sensor has the advantages of low cost, ease of fabrication, and large strain capability and could find wide applications in the field of soft robotics.
