Airflow sensors hold significant application value in environmental monitoring, biomedicine, aerospace, motion sensing systems, and wearable devices. Traditional airflow sensors primarily rely on mechanical deformation under piezoresistive, capacitive, optical, or magnetic effects, or utilize thermal exchange between heating elements and airflow to output signals via resistance changes. However, conventional sensors often suffer from rigid structures, bulky size, and dependence on external power, limiting their development in flexible, portable, and self-powered sensing. Notably, flexible sensors enhance fit and comfort, enabling stable, continuous signal monitoring, making them ideal for wearables. Thus, developing flexible airflow sensors with self-powering capabilities is crucial to expand applications and improve performance.
