Abstract
The advent of catheter-based minimally invasive surgical instruments has provided an effective approach for diagnosing and treating cardiovascular diseases. Advanced sensor-equipped catheter products have gradually emerged, demonstrating remarkable functionality. Notably, pressure sensor catheters have found extensive application in the diagnosis of cardiovascular diseases. However, the key packaging technologies for these devices remain underexplored and insufficiently mastered, posing challenges to their further development and widespread adoption. This study aims to develop an integrated packaging technology for implantable catheter and carbon nanotube (CNT) pressure sensors, encompassing methods for sensor electrical connections and encapsulation. Furthermore, we present a novel technique for replicating pyramid-shaped microstructures using a PDMS template. This method enables the uniform application of CNT/PDMS nanocomposite material onto the PDMS mold, facilitating the cost-effective production of pyramidshaped piezoresistive sensors.
