Analysis of lattice structure properties toward emerging new tactile sensations

Abstract

This paper describes an analysis of previous studies on lattice structure mechanics and discusses the issues and future measures for emerging new tactile sensations. Through cluster analysis, these studies can be classified into four distinct groups: (1) Studies focused on improving the compressive performance of structures and products made from a single material, (2) Studies aimed at obtaining knowledge about the compressive properties in structures composed of a single material, (3) Studies focused on structures composed of multiple materials, and (4) Studies focused on specific materials. From this analysis, six issues in emerging tactile sensations were identified, leading to the following proposed future measures: (I) Apply ideas extracted from research on the mechanical properties of lattice structures to the creation of tactile sensations, and clarify how these relate to sensory impressions. (II) Fabricate samples with various mechanical properties, not limited to compressive strength and stiffness. (III) Fabricate samples by combining multiple materials. (IV) Fabricate samples with gradient properties. (V) Fabricate samples using a wide range of materials, such as hard plastics and elastomers.
