Fig. 1: Overview of the native artery and electronic vascular conduit.
a The native artery is composed of the intima, media and externa, endowing the artery with excellent mechanical properties and hemostasis-thrombus balance ability. The nerve plexus encompasses the artery to sense and regulate blood pressure. b Our electronic vascular conduit comprises i) a biomimetic artificial graft designed for arterial reconstruction and ii) an integrated triboelectric sensor for real-time and in situ hemodynamic monitoring. b-ii illustrates the triboelectric sensor and its electron cloud and potential energy well model for electricity generation. EA and EB represent the occupied energy levels of electrons.
