    • A sensor (100) for detecting input force and/or torque with six degrees of freedom for use as a computer input device is provided. The sensor has a technically simple detection mechanism which obviates the need for complex and fragile securing components. A user-manipulable core (106) is enclosed in a casing (109). Electrodes (114) in the casing (109) are separated from the core (106) by a layer of elastically deformable conductive polymer (108). Electric current flows between the core (106) and the electrodes (114). The polymer (108) has variable resistivity depending on the stress it experiences. Manipulation of the core (106) causes deformation of the polymer (108); the type of deformation, and hence the type of force/torque applied to core (106), is determinable from the currents flowing through the electrodes (114).
    • 提供了用于以六自由度检测用作计算机输入装置的输入力和/或扭矩的传感器(100)。 传感器具有技术上简单的检测机制,可以避免对复杂和易碎的固定部件的需要。 用户可操纵的芯(106)被封装在壳体(109)中。 壳体(109)中的电极(114)通过一层可弹性变形的导电聚合物(108)与芯部(106)分离。 电流在芯(106)和电极(114)之间流动。 聚合物(108)具有取决于其经历的应力的可变电阻率。 芯部(106)的操纵导致聚合物(108)的变形; 变形的类型以及因此施加到芯(106)的力/扭矩的类型可以从流过电极(114)的电流确定。
