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.

Keywords: cardiovascular electronics; personalized healthcare; pulse wave monitoring; smart textiles; triboelectric nanogenerators.
