Disclosed is a wearable motion capture glove based on a flexible optical fiber, relating to the field of motion capture. The wearable motion capture glove includes a glove body, multiple motion acquisition sensing devices, and a glove packaging tool. Each motion acquisition sensing device includes a data acquisition and processing module, a circuit splint, and a flexible polymer profiled optical fiber. The data acquisition and processing module includes a motion capture data acquisition module, and a motion capture data processing module. The flexible optical fiber and the motion capture data acquisition module are firmly packaged using the circuit splint and the glove packaging tool, and then are fixed to a corresponding position of a finger joint of a wearer, such that the glove can be worn more closely to the finger joint, and data acquisition is more stable and accurate.

The present invention provides a tapered side-polished fiber-optic biosensor (FOBS) and a method for preparing a tapered side-polished fiber (SPF). The biosensor includes a broadband light source, a first single-mode fiber, a tapered SPF, a second single-mode fiber, and a spectrometer. The broadband light source is connected to the tapered SPF through the first single-mode fiber, and the tapered SPF is connected to the spectrometer through the second single-mode fiber. The broadband light source is configured to emit a light wave. The spectrometer is configured to display a spectrum corresponding to a light wave passing through the first single-mode fiber, the tapered SPF, and the second single-mode fiber successively. In the present invention, a fiber side-polishing technology is combined with a fiber tapering technology to construct a tapered SPF, and a spectrum changes by changing a refractive index around a side-polished tapered region, thereby measuring the refractive index. In addition, the tapered SPF provided in the present invention can generate a Vernier effect, thereby improving the sensor's anti-electromagnetic interference and sensitivity to refractive index measurement.
