Abstract

Abstract : Arterial pulse waves are regarded as vital diagnostic tools in the assessment of cardiovascular disease (CVD). Because of their high sensitivity, rapid response time, wearability, and low cost, textile triboelectric nanogenerators (TENGs) are emerging as a compelling biotechnology for wearable pulse wave monitoring. We discuss sensing mechanisms for pulse-to-electricity conversion, analytical models for calculating cardiovascular parameters, and application scenarios for textile TENGs. We provide a prospective on the challenges that limit the wider application of this technology and suggest some future research directions. In the future, textile TENGs are expected to make an impact in the fields of wearable pulse wave monitoring and CVD diagnosis. Highlights: Cardiovascular disease (CVD) is the main cause of death globally, and arterial pulse waves are vital diagnostic tools for assessing CVD. Textile triboelectric nanogenerators (TENGs) provide a highly sensitive, self-powered, and low-cost biotechnology for pulse-to-electricity conversion while maintaining the advantageous features of textiles such as superior wearing comfort and stability. Clinical parameters, such as heart rate, pulse wave velocity, and blood pressure, can be calculated from pulse waveforms acquired by textile TENGs for CVD diagnosis in a continuous, timely, and accurate manner. Textile TENGs can be further connected with terminals to enable real-time personalized healthcare monitoring and clinical information exchange with telemedicine in a non-clinical environment.
