摘要

The experiments conducted show that it is possible to achieve highly precise translation of flexible micropipettes in defined non-rectilinear trajectories. We have shown that by varying the bend radius systematically, we can quantify the relationship between hysteresis and geometrical configuration. Both experimentally and through simulations, we have shown an inverse linear correlation between the measured hysteresis and the bend radius, that is, the hysteresis is largest for the smallest bend radius for the same spanned arc length. In the future more simulations will be set up to verify the experimental data with more accurate radii and friction coefficients. Currently the simulations are slow and very sensitive to input parameters such as the friction coefficient. More superficial models are being worked on using a state friction models or other integrators.
