This Thesis explores how human are able to modulate
intrinsic hand and arm stiffness. The question is increasingly relevant as human and robots start collaborating inside same workspaces and introducing compliance allows tuning forces due to impacts. Mechanisms are developed for measuring purely human mechanical properties, and factors for varying the known force--stiffness coupling are studied. Conclusively, the transfer of gained insights to robots, i.e. the linear relation between force and stiffness, and biarticular joint coupling, is analyzed and discussed.
