Embodiment Construction
[0040] The following terms are defined for use in this specification including the appended claims:
[0041] • Sensation of a surface (also referred to as sensory properties) is defined as the sensory perception of the nature of the surface, which depends on the physical stimulus the surface presents to the skin or other tissue in contact with the surface. Examples of physical stimuli include, but are not limited to, normal force, shear force, static friction, and the like.
[0042] ● Engineered feel is defined as the sensory perception of the nature of a physically modified surface that has been physically modified such that it feels different from that of an unmodified surface including the material making up the engineered surface, where the physical modification controls the At least one haptic parameter includes friction, fine roughness, and modulus of elasticity.
[0043] An active layer is defined as a surface portion of a homogeneous structural layer of a first materi...

Abstract
The invention discloses a homogeneous material layer, comprising a base layer and at least one effective layer is disclosed. The material layer is made of a first material characterized by a bulk modulus of elasticity. The effective layer is defined by a plurality of projections that project from the base layer. Each projection includes a stalk and a cap having an end face. The height-to-width aspect ratio of the stalks is selected such that the effective layer has an effective modulus of elasticity that is lower than the bulk modulus of elasticity. The arrangement of the projections is selected such that the end faces are spaced along at least one dimension by a spacing that is less than or equal to one millimeter, thereby controlling the fine roughness of the effective surface. Control of the effective modulus and the spacing of the end faces enables control of the feel of the effective layer.
Description
[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Application Serial No. 62 / 215,506, filed September 8, 2015, entitled "Composition Comprising Sensory-Specific Material and Method of Manufacture" (Attorney Docket No. 3080-002PR1), which application is incorporated herein by reference. If there is any contradiction or or linguistic inconsistency between this application and one or more of the cases already incorporated by reference that may affect the interpretation of the claims in this case, the claims in this case shall is interpreted to be consistent with the language in this case. technical field [0003] The present invention relates generally to materials, and more particularly to structured surface materials. Background technique [0004] Materials with true or enhanced touch sensitivity would be advantageous in many applications. For example, items such as gloves, surgical gloves, handles, containers ...
