摘要: Abstract The potential for large deformation of the ionic polymer–metal composite (IPMC) is useful in developments biomedical device and miniature robot. goal this study to investigate feasibility developing a sensing/actuating IPMC transducer as head an active guide-wire cardiac catheterization. approach employs amplitude modulation–demodulation technique obtain deformation-sensing signal converted from variation electrical resistances electrodes. According solvents uptake conditions, three types were produced tested sensing actuating functions. Besides, simulation catheterization procedure was demonstrated with guide-wire. From estimated experimental results, relationship between tip-displacement representing verified. proportional small deformation. tests showed that sensitivity depended on condition material processing solvent IPMC. In addition, there trade-off functions design IPMC, electric power applied actuation may interrupt migration Differentiating signals deformed undeformed alleviate interference. demonstration simulated exhibited checking bifurcation blood vessels without integrating bulky sensor or adjusting curvature IPMC-based guide wire.
