Abstract

An intelligent skin based on a small-size distributed optical fiber sensing array. The intelligent skin includes an epidermis sensing array, an embedded optical fiber sensing array, a data collection system module, and a data processing mode recognition module. The body of the intelligent skin is made of a flexible material. The embedded optical fiber sensing array in an epidermis includes a plurality of all-fiber interferomatic sensing arrays. The data collection system module includes a broadband light source, an optical combiner/splitter, an optical path change-over switch, a signal detector and a computer. The data processing mode recognition module includes mode recognition and training of a neural network. The intelligent skin further includes an external display software used to perform intelligent sensing recognition for sense of touch, position, shape, and ingredient, temperature and vibration of an object and so on.
