a Conceptual deployment of the smart stent within a coronary artery, incorporating dual wireless pressure sensors at the proximal (Pa) and distal (Pd) sites relative to a stenotic lesion. b Design of the MEMS-based wireless pressure sensor, featuring an enlarged capacitor plate for enhanced mechanical stability and an air-elimination channel to equalize internal and external pressure. c Integration of the pressure sensors with the 3D-printed hybrid PCL/PLA stent using a connection hole and water-soluble PVA interface
