)、快速响应(160 ms)和恢复时间(60 ms)以及低检测限(40 Pa). 除此之外，该传感器还继承了皮革本身柔性和透气的特点，使其能够在实现高质量传感的同时保证穿戴舒适性，尤其适用于脉搏检测的使用场景. 该传感器与微处理器和神经网络构建的智能监测系统能够实现人体脉搏信号的处理以及高准确度的实时血压预测，突破传统血压测量方法的瓶颈，在人体健康监测和疾病早期诊断领域展现出了巨大的应用潜力.

Abstract

The development of flexible electronic technology drives the application of flexible sensors in the fields of human health monitoring and remote diagnosis and treatment of diseases. In this study

a pressure sensor was fabricated by taking advantage of the inherent multi-scale pore structure in leather

a polymeric material. The sensor was then combined with a microcontroller and a neural network algorithm to construct a real-time

comfortable and breathable blood pressure monitoring system. The pressure sensor based on the leather/carboxylated carbon nanotube composite exhibited high sensitivity (14.83 kPa

-1

)

fast response (160 ms)

short recovery time (60 ms) and a low detection limit (40 Pa). In addition

this sensor inherited the intrinsic

flexibility and breathability of leather

which enabled it to ensure wearing comfort while achieving high-quality sensing performance

making it particularly suitable for pulse detection scenarios. The intelligent monitoring system constructed by integrating this sensor with a microprocessor and a neural network could process human pulse signals and realize high-accuracy real-time blood pressure prediction. It breaks through the bottlenecks of traditional blood pressure measurement methods and demonstrates great application potential in the fields of human health monitoring and early diagnosis of diseases.
