Abstract
Smart medical phantoms for training and evaluation of endovascular procedures ought to measure impact forces on the vessel walls worth protecting to provide feedback to clinicians and articulated soft robots. Recent commercial smart phantoms are expensive, usually not customizable to different applications and lack accessibility for integrated development. This work investigates piezoresistive films as highly integratable flexible sensors to be used in arbitrary soft vessel phantom anatomies over large surfaces and curved shapes providing quantitative measurement in the force range up to 1 N with 0.1 N resolution. First results show promising performance at the point of calibration and in a 5 mm range around it, with absolute measuring error of 28 mN and a standard deviation of ±10 mN and response times <500 ms. Future work shall address the optimization of response time and sensor shapes as well as the evaluation with experienced clinicians.
