Handles with Reentrant Cells for Use as Oar Handles: Design Considerations, Physical Characteristics, and End‐Users’ Perceptions
Rowing is a sport that requires athletes to perform the action of pulling and rotating an oar by hand, applying forces of considerable magnitude. Herein, inspired by the notion that auxetic materials and metamaterials behave differently compared to their conventional counterparts, it is examined how a handle prototype, specifically designed to incorporate the classic re‐entrant motif, behaves and how end‐users perceive it. Physical experiments conducted on such prototype, which measured the contact pressures, suggest that on average, higher pressures are measured when pulling with this reentrant grip compared to its non reentrant counterpart, indicating that this re‐entrant prototype should feel firmer. More importantly, respondents of a survey are asked to give their feedback, and different views on which handle they would prefer to use are provided. The ones who preferred the prototype with the reentrant features report that they preferred it because it felt firmer and allowed for a better grip. This suggests that there is potential for further investigation into whether handles, oar handles in particular, made from auxetic components, re‐entrant cells, or other motifs which are well known for their negative Poisson's ratio characteristics, could provide a better and more secure grip and be used in sports applications.
期刊介绍:
physica status solidi is devoted to the thorough peer review and the rapid publication of new and important results in all fields of solid state and materials physics, from basic science to applications and devices. Being among the largest and most important international publications, the pss journals publish review articles, letters and original work as well as special issues and conference contributions.
physica status solidi b – basic solid state physics is devoted to topics such as theoretical and experimental investigations of the atomistic and electronic structure of solids in general, phase transitions, electronic and optical properties of low-dimensional, nano-scale, strongly correlated, or disordered systems, superconductivity, magnetism, ferroelectricity etc.
