Mechanical force sensing is an important and integral component in the study of the viscoelastic properties of biological cells. In this study, a vision-based non-contact force sensing technique for real-time stressing of biological cells by a vision-guided robotic micromanipulation system is introduced. The system is capable of providing real-time external mechanical stressing on biological cells...
Biological cells possess biochemical modules and physical shapes to maintain appropriate biological function. Different types of force and deformation are applied on cells to investigate the response and mechanical properties. In the biophysics field, studies use indentation deformation on cell membranes to examine the elastic-viscoelastic properties of biological cells. Experiments in different predefined...
This study examines micromanipulation accuracy in pointing and in tracing a circle, using a novel contact-free measurement system. Three groups of subjects enable us to investigate the influence of age and micromanipulation expertise. The results show that, for all groups of subjects, a 10times magnification increases accuracy, but larger magnification does not improve it further. Expertise leads...
