Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0033] Such as figure 1 As shown, a wearable glove based on sensitized plastic optical fiber in this embodiment mainly includes a fingertip base 11, a fingertip support 12, a palm integrated module 2, a wrist base 31, a wrist telescopic part 32, a wrist Integrated module 4 , wrist belt 51 , palm belt 52 , thumb connecting piece 6 , thumb rotating piece 7 . Among them, the ring buckle 121 on the fingertip bracket 12 fastens and wears the entire fingertip base 11 on the fingers, and the wrist strap 51 and the palm strap 52 connect the palm integrated module 2 and the wrist integrated module 4 respectively. It is fastened on the palm and forearm so that the finger base 11 and the wrist base 31 can follow the movement of the fingers and the wrist respectively to generate bending strain. U-shaped and straight sensitized plastic optical fibers are ...

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.

Description

technical field [0001] The invention belongs to the field of optical fiber sensing and wearable sensors, in particular to a wearable glove based on a sensitized plastic optical fiber. Background technique [0002] As sensing elements and data acquisition systems continue to develop towards flexibility and miniaturization, wearable devices that can obtain human motion information and physical sign parameters are increasingly appearing in daily life. From wearable wristbands that can easily and quickly obtain human pulse and blood pressure, to wearable motion capture systems that accurately capture body movements, it can be seen that wearable devices are becoming more and more diverse, and are used in medical, military, sports , entertainment and many other aspects have shown important research value and application potential. [0003] Among wearable devices, wearable gloves that can accurately obtain hand posture and then combine with virtual reality and rehabilitation train...
