It was previously suggested that the mechanical properties of the fingertip could be characterized by elasticity from dc to about 100Hz and by viscosity above this frequency. Using a specifically designed high mobility probe, we accurately measured the impedance of the fingertips of seven participants under a variety of conditions relevant to purposeful touch. Direct measurements vindicated previous indirect observations. We also characterized the dependency of the fingertip impedance upon normal load, orientation, and time.
先前有人提出，指尖的力学特性可以通过直流到约 100Hz 的弹性和高于此频率的粘性来表征。使用专门设计的高迁移率探头，我们在与有目的触摸相关的各种条件下，准确测量了七名参与者指尖的阻抗。直接测量证实了先前的间接观察。我们还描述了指尖阻抗随法向载荷、方向和时间的变化特性。
