Implantable Membrane Sensors and Long-Range Wireless Electronics for Continuous Monitoring of Stent Edge Restenosis.

ABSTRACT: Continuous monitoring of vascular stent health is crucial for high-risk patients. Current approaches predominantly rely on inductive coupling, which limits the wireless reading distance and requires precise antenna alignment with implanted stents. Here, we present a long-range wireless electronic system that incorporates a low-resistance inductive stent fabricated via laser micromachining and electroplating of biocompatible metal films, forming a mechanically robust and conductive interface optimized for radar interrogation. A conformal, flexible capacitive pressure sensor is developed from soft dielectric elastomers and integrated within the stent's structure, enabling localized detection of hemodynamic pressure changes indicative of stent-edge restenosis.
