Abstract
In this paper, we introduce an innovative high-sensitivity wireless LC pressure sensor that is carefully designed for integration into biodegradable polymer stents, providing a remarkable improvement in restenosis detection. The key to this breakthrough is a significant increase in the cavity volume of the capacitive pressure sensor in the design. This design optimization improves the sensor sensitivity by a factor of 7. This improved sensitivity has been consistently demonstrated through our comprehensive performance evaluation (phantom and animal experiment) in air and liquid conditions while confirming the robustness and reliability of the sensor in various environments. The smart stent proposed in this study is the first to demonstrate practical medical potential.
