An Artificial Intelligence‐Motivated Skin‐Like Optical Fiber Tactile Sensor

Soft and stretchable tactile sensors have received extensive attention for their potential applications in wearables, human–robot interaction, intelligent robots. Herein, inspired by the functions of skin somatosensory signal generation processing, an artificial intelligence-motivated skin-like optical fiber (SOFT) sensor is proposed. It features multifunctional touch interaction capabilities including amplitude position tensile strain. Four Bragg gratings (FBGs) are embedded a three-layer laminate structure SOFT sensor, forming flexible sensing array with stretchability larger than 20%. Fusing two-level cascaded neural network, magnitude contact force can be distinguished simultaneously. The recognition accuracy up to 92.41% error less 4.2% within range 0–3.5 N. Several sensor-based interactive pressure password interface music playback achieved combining intelligence spatiotemporal dynamic logic analysis. Furthermore, also capable complex scenes involving tension sensing, such as dexterous hand perception control. This work provides novel insights into intelligence-based integrated that shows broad promise prosthetics bionic robotic.
