Dilatant fluid based tactile display -Basic concept

What is it about?

The research addresses the evolving landscape of tactile interfaces and proposes a multi-purpose oriented tactile display using a dilatant fluid with dynamic elasticity and deformable properties. In recent years, there has been a proliferation of tactile displays, ranging from those conveying physical information about the environment, such as object shapes or forces, to devices focused on simulating cutaneous sensations. However, the latter devices are often specialized and not versatile, requiring different devices for various expressions of objects. The proposed display stands out as a multi-purpose solution, leveraging a deformable and elasticity-changeable fluid. This fluid allows for the creation of a new type of display capable of expressing a variety of elasticities and controllable deformations. Unlike specialized devices for specific expressions, this multi-purpose oriented display offers flexibility in representing different tactile sensations without the need for distinct devices for each expression of an object. The core innovation lies in the use of a dilatant fluid, known for its dynamic elasticity and deformable nature. By employing this fluid, the research introduces a tactile display that can dynamically adapt its properties, opening up possibilities for a wide range of tactile expressions in a single, versatile device. The research thus contributes to the development of more adaptable and multi-functional tactile interfaces, potentially finding applications in various fields requiring diverse tactile feedback.
