触觉反馈在我们操纵物体时至关重要。特别是与物体刚度有关的信息可以帮助促进精细运动控制。在这项研究中，我们试图确定是否可以使用触觉反馈提供的经皮电刺激外周nerves.ApproachUsing刺激电极网格放置沿着上臂的内侧，正中和尺神经束的不同刚度水平的对象被识别，有针对性地唤起触觉的手掌侧的手。刺激电流的幅度调制实时与指尖力记录从传感器假手。为了评估哪种刺激模式更关键，对象刚度被编码的变化率的刺激幅度或峰值刺激幅度的水平，作为假肢抓住objects.Main resultsBoth编码方法允许受试者区分不同的刚度水平的对象与> 90%的准确性。两种编码方法之间没有显著差异，这表明刺激幅度的变化率和刺激幅度的峰值都可以有效地提供物体的刚度信息。显著性结果表明，使用经皮神经刺激可以引起描述各种物体刚度水平的触觉感觉。与对象刚度相关联的触觉反馈可以促进对象操纵/交互。当结合物体刚度信息时，它还可以改善人机交互期间的用户体验。
ObjectiveHaptic feedback is crucial when we manipulate objects. Information pertaining to an object's stiffness in particular can help facilitate fine motor control. In this study, we seek to determine whether objects of different stiffness levels can be recognized using haptic feedback provided by transcutaneous electrical stimulation of peripheral nerves.ApproachUsing a stimulation electrode grid placed along the medial side of the upper arm, the median and ulnar nerve bundles were targeted to evoke haptic sensation on the palmar side of the hand. Stimulation current amplitude was modulated in real-time with the fingertip force recorded from a sensorized prosthetic hand. In order to evaluate which stimulation pattern was more critical, object stiffness was encoded either by the rate of change of the stimulus amplitude or the level of peak stimulus amplitude, as the prosthesis grasped the objects.Main resultsBoth encoding methods allowed the subjects to differentiate objects of different stiffness levels with> 90% accuracy. No significant difference was observed between the two encoding methods, which indicated that both the rate of change of the stimulation amplitude and the peak stimulation amplitude could effectively provide stiffness information of the objects.SignificanceThe outcomes suggest that it is possible to elicit haptic sensations describing various object stiffness levels using transcutaneous nerve stimulation. The haptic feedback associated with object stiffness can facilitate object manipulation/interactions. It may also improve user experience during human–machine interactions, when object stiffness information is incorporated.
