Electrical stimulation of tactile nerve fibers that innervated an amputated hand results in vivid sensations experienced at a specific location on the phantom hand, a phenomenon that can be leveraged to convey tactile feedback through bionic hands. Ideally, electrically evoked tactile sensations would be experienced on the appropriate part of the hand: Touch with the bionic index fingertip, for example, would elicit a sensation experienced on the index fingertip. However, the perceived locations of sensations are determined by the idiosyncratic position of the stimulating electrode relative to the nerve fascicles and thus difficult to predict or control. This problem could be circumvented if perceived sensations shifted over time so that they became consistent with the position of the sensor that triggers them. We show that, after long term use of a neuromuskuloskeletal prosthesis that featured a mismatch between the sensor location and the resulting tactile experience, the perceived location of the touch did not change.

长期使用致敏的仿生手不会重塑触感

触及断肢手的触觉神经纤维的电刺激会导致在幻影手的特定位置经历生动的感觉，这种现象可通过仿生手传达触觉反馈。理想情况下，会在手的适当部位产生电诱发的触感：例如，用仿生食指触摸会引起食指上的感觉。然而，感觉的感知位置由刺激电极相对于神经束的特异位置确定，因此难以预测或控制。如果感知到的感觉随着时间推移而发生偏移，从而使其与触发它们的传感器位置保持一致，则可以避免该问题。我们证明
