This study aims to reveal some of the fundamental sensory mechanisms underlying the uniquely human ability to manipulate objects and use tools. Signals from touch receptors are crucial for controlling grip forces so that delicate objects are held without slipping, or being crushed by excessive force. Yet we know little about how such sensory information is obtained and how it is used for the motor control. By analysing hand movements during object manipulation and recording sensory signals from single human nerve fibres we will investigate how certain types of movement shape richness of available sensory information. This knowledge will facilitate the development of next generation sensory-controlled prosthetics and robotic manipulators.

这项研究旨在揭示人类操纵物体和使用工具的独特能力背后的一些基本感觉机制。来自触摸感受器的信号对于控制握力至关重要，这样就可以握住脆弱的物体，而不会滑倒，也不会被过度的力量压碎。然而，我们对这种感觉信息是如何获得的，以及它是如何用于运动控制的知之甚少。通过分析物体操纵过程中的手运动和记录单个人类神经纤维的感觉信号，我们将调查某些类型的运动如何形成丰富的可用感觉信息。这些知识将促进下一代感官控制假肢和机器人操作手的发展。
