触觉领域的目标是创造操纵触觉的技术。在虚拟现实和增强现实中，触觉设备用于触摸，扬声器和RGB显示器用于听觉和视觉。利用微型马达或其它小型化机械装置（例如，用于振动和气动致动）产生有趣的效果，但与再现真实的材料的感觉相差甚远。它们特别缺乏概括的表面性质：精细的质地、摩擦力、粘弹性、粘性和柔软性。本进展报告的中心论点是，为了再现日常物品的感觉，必须对材料的性质进行分子控制;最终，这种控制将使材料的设计能够在真实的时间内改变这些性质。刺激响应有机材料，如聚合物和复合材料，是一类可以改变其氧化态，导电性，形状和流变特性的材料，因此可能在未来的触觉技术中有用。此外，在触觉感知的研究中使用这种材料可以帮助阐明人类触觉敏感性的极限。所描述的工作代表了这一新的研究领域的开端，其中定义方法是材料科学和心理学的结合。
The goal of the field of haptics is to create technologies that manipulate the sense of touch. In virtual and augmented reality, haptic devices are for touch what loudspeakers and RGB displays are for hearing and vision. Haptic systems that utilize micromotors or other miniaturized mechanical devices (e.g., for vibration and pneumatic actuation) produce interesting effects, but are quite far from reproducing the feeling of real materials. They are especially deficient in recapitulating surface properties: fine texture, friction, viscoelasticity, tack, and softness. The central argument of this progress report is that in order to reproduce the feel of everyday objects, molecular control must be established over the properties of materials; ultimately, such control will enable the design of materials which can change these properties in real time. Stimuli-responsive organic materials, such as polymers and composites, are a class of materials which can change their oxidation state, conductivity, shape, and rheological properties, and thus might be useful in future haptic technologies. Moreover, the use of such materials in research on tactile perception could help elucidate the limits of human tactile sensitivity. The work described represents the beginnings of this new area of inquiry, in which the defining approach is the marriage of materials science and psychology.
