Wearable glove based on sensitization plastic optical fibers

Abstract

The wearable glove based on sensitization plastic optical fibers comprises a finger tip base (11), a finger tip support (12), a palm integration module (2), a wrist base (31), a wrist connecting piece (32), a wrist integration module (4), a wrist girdle (51), a palm girdle (52) and a finger rotating piece (6). Sensitized plastic optical fiber loops subjected to surface structure treatment are embedded in the finger tip base (11) and the wrist base (31), and recognition of finger and wrist movement postures is achieved through optical signal demodulation: plastic optical fibers generate light leakage under the macroscopic bending condition, the light leakage of the plastic optical fibers in the bending state is further enhanced through surface structure treatment, and monitoring of finger and wrist motion states is achieved by detecting changes of light intensity in the optical fiber. According to the invention, the plastic optical fiber subjected to surface sensitization treatment is used as a bending strain sensitive element, so that the detection sensitivity is enhanced, and the flexibility of the plastic optical fiber is fully utilized to realize accurate following of hand movement.
