This article describes the design and development of a thimble-sensor used for virtual object manipulation. This thimble is specially designed to provide the force information applied on an object by using four FlexiForce sensors and a fingertip orientation. Likewise, the aim of this paper is focused on the mechanical design, which relies on developing an adjustable mechanical tool non-finger-size...
When a person moves or presses with an individual finger other fingers also produce a force (Kilbreath and Gandevia 1994; Li et al. 2004; Zatsiorsky et al. 2000). Several factors are known to contribute to this response: (1) peripheral mechanical coupling, (2) multi-digit motor units, and (3) diverging central commands. This phenomenon, known as enslaving, has traditionally been studied in isometric...
Haptic and/or tactile information has been paid attention as the third multimedia information. An electric motor with the disturbance observer is a good candidate to achieve haptic ability because it is possible to match actuation and sensation. Furthermore, it is possible to convert haptic energy into electric energy. The paper discusses necessity for the framework of haptic energy transmission....
The atomic force microscope (AFM) has been widely used as a nano-effector with a function of force sensing to detect interaction forces between an AFM tip and a sample, thereby controlling the process of the nanomanipulation. However, both the extent and accuracy of force application are significantly limited by the nonlinearity of the commonly used optical lever with a nonlinear position-sensitive...
