The wearable optical fiber sensors have demonstrated significant promise in the realm of health monitoring in recent times. These sensors utilize the flexibility and exceptional sensitivity of optical fibers to precisely measure many physiological aspects of the human body, including heart rate, breathing rate, mobility status, and body temperature. Optical fiber sensors usually have good biocompatibility and anti‐interference capabilities, can be integrated into flexible materials, and are suitable for long‐term wear. It can be integrated into clothing, patches, or accessories to provide continuous, real‐time health data monitoring, providing important support for personalized medicine and remote health management. This paper primarily presents the fundamental operating concept of wearable optical fiber sensors and their use in monitoring physiological signals across multiple domains. In conclusion, this paper provides a summary of the limitations and future prospects of wearable fiber sensors using optical fiber technology.

A fiber optic fabric sensor for respiratory monitoring of smart clothing is investigated. The sensor consists of a multilayer composite of a stretchsensitive optical fiber, thermoplastic polyurethane elastomer (TPU), and an elastic fabric.A heatingbased sizing method for the multibending cascade structure of polymer optical fibers is proposed to prepare stretchsensitive optical fibers with precise characteristic dimensions. Using the TPU material, the bonding of stretchsensitive optical fibers, TPU material, and fabric is realized by ironing to form a laminated fabric sensor. The prepared fabric sensor has no bubbles and wrinkles between the layers, has good production repeatability, and can be connected with garments without sewing to enhance their comfort and aesthetics. Experiments show that the sensor has a strain coefficient of up to 71. 01, a stretch rate of up to 83%, a hysteresis error of <12%, and a unidirectional stretchsensing capability. The designed respiration monitoring sample garment is put through its paces, and the measurements revealed that it is capable of capturing a clear respiration waveform under a variety of breathing frequencies, wearer postures, and movement states. The maximum error of respiration rate is < 2 times/min and the average error is within 0. 8 times/min.

With the growing demand for sustainable, wearable, and clean energy, triboelectric nanogenerator (TENG) has attracted wide attention. Textilebased triboelectric nanogenerator (T -TENG) has the advantages of lightweight, soft, and comfortable wearing, and has been the focus of design and research. Since fiber and yarn are the basic units of textiles, fiber/yarnbased TENG can be prepared into fabrics with different structures or integrated into other fabrics through subsequent processing, which can fully retain the advantages of fabric structure itself. Therefore, the design and development of fiber/yarnbased TENG with excellent performance is considered to be one of the fundamental solutions for the manufacture of T -TENG. This paper introduces the basic principles of TENG, fiber/yarnbased TENG manufacturing technology, and the integrated strategy of fiber/yarnbased TENG. Finally, the challenges and prospects for the preparation of fiber/yarnbased TENG are presented.
