摘要：

This paper presents the perforated design of a piezoelectric tube that will be employed as a self-powered Smart Stent for real-time blood pressure monitoring. The proposed Smart Stent was made of polyvinylidene fluoride (PVDF), which can harvest energy from pulse-motion low-frequency vibration such as blood flow. This study focuses on a unique pattern of the perforation added to the Smart Stent. We observed that the perforation design of Smart Stent varies its sensitivity to pressure change and produces different energy harvesting performances. The eight different perforations design of the Smart Stent were fabricated, examined, and reported their performances.
