An optical soft skin system for multi-modal sensing, comprising: a flexible waveguide substrate (10) capable of changing its light wave propagation when encountering different deformation modes; at least one light source (12) located within the waveguide substrate (10), arranged to transmit light into the waveguide substrate (10); at least one light receiver (14) located within the waveguide substrate (10) to receive light passing through the waveguide substrate (10) and to provide a data set of properties of the received light; and a processor (20) for decoding the data set into at least one of a strain and a displacement by a computational model to determine a sensing modality of the waveguide substrate (10). 一种用于多模态感测的光学软皮肤系统，包括：柔性波导基板(10)，能够在遇到不同的变形模式时改变其光波传播；位于波导基板(10)内的至少一个光源(12)，被布置成将光传输到波导基板(10)中；位于波导基板(10)内的至少一个光接收器(14)，以接收穿过波导基板(10)的光并提供接收到的光的属性的数据集；以及处理器(20)，用于通过计算模型将数据集解码为应变和位移中的至少一个，以确定波导基板(10)的感测模态。
