A tactile gripper on an optical fiber for perception and actuation.

ABSTRACT: Optical fibers with integrated robotic microstructures are promising for cutting-edge applications. However, the development of microbots on a fiber system for synergistic sensing and actuation is challenging. Herein, inspired from natural Bobbit worm, we report a tactile gripper-on-a-fiber system that integrates wave spring, planar reflector with a scattering cone and a smart gripper on a single-mode fiber. The wave spring fabricated via two-photon polymerization of SU-8 can convert the applied micro-force into detectable stretching or compression, serving as a Fabry-Perot interferences sensor. Additionally, a pH responsive gripper with SU-8 frames and bovine serum albumin muscles is integrated with the wave spring, forming the tactile gripper-on-a-fiber system. As a proof-of-concept, the
