With
the advantages of high flexibility, strong real-time monitoring
capabilities, and convenience, wearable devices have shown increasingly
powerful application potential in medical rehabilitation, health monitoring,
the Internet of Things, and human–computer interaction. In
this paper, we propose a novel and wearable optical microfiber intelligent
sensor based on a wavy-shaped polymer optical microfiber (WPOMF) for
cardiorespiratory and behavioral monitoring of humans. The optical
fibers based on polymer materials are prepared into optical microfibers,
fully using the advantages of the polymer material and optical microfibers.
The prepared polymer optical microfiber is designed into a flexible
wave-shaped structure, which enables the WPOMF sensor to have higher
tensile properties and detection sensitivity. Cardiorespiratory and
behavioral detection experiments based on the WPOMF sensor are successfully
performed, which demonstrates the high sensitivity and stability potential
of the WPOMF sensor when performing wearable tasks. Further, the success
of the AI-assisted medical keyword pronunciation recognition experiment
fully demonstrates the feasibility of integrating AI technology with
the WPOMF sensor, which can effectively improve the intelligence of
the sensor as a wearable device. As an optical microfiber intelligent
sensor, the WPOMF sensor offers broad application prospects in disease
monitoring, rehabilitation medicine, the Internet of Things, and other
fields.
