The assessment and examination of anthropometric measures in children are of paramount significance in the advancement and creation of furniture, tools, and toys that specifically addresses the requirements of children as users. The dataset analyzed a total of 354 children from Jordan, divided into six distinct age groups ranging from 6 months to 9 years. The linear static measures included the skeletal dimensions pertaining to the distances between joints in the body, as well as the dimensions of the middle and lower bodies. It consists of 23 anthropometric measurements such as: stature, sitting height, knee height, eye height sitting, chest depth and shoulder breadth and others. The dataset supports the article "Preliminary and Comprehensive Static Anthropometric Measurements of Jordanian Children for Various Age Groups" [1]. The available data may initiate the establishment of a connection between anthropometric measurements and other design attributes used in Jordanian society. Additionally, these data have the potential to provide valuable insights for the development of diverse functional products, including clothing and safety equipment specifically tailored for the needs of children in Jordan.

Molybdenum chips are vital in manufacturing photovoltaic cells and electronics because they offer a combination of high reliability, corrosion resistance, and exceptional electrical conductivity. These qualities make them suitable for applications demanding these characteristics. This study delves into the behavior of thin molybdenum films deposited on plastic substrates under increasing stress. Films of 100 nm and 200 nm thicknesses were stretched, revealing intricate relationships between crack formation, film thickness, and electrical conductivity. Scanning electron microscopy captured the evolution of cracks, initially forming perpendicular to stress and later branching at roughly 30 degrees, hinting at anisotropic material behavior. Thicker films displayed lower crack density and less branching, highlighting their enhanced stress resistance. Further, secondary cracks short between the original cracks was developed. Percentage change of electrical resistance mirrored this trend, gradually increasing with strain before a sharp spike and eventual disconnection due to crack-induced conductivity loss. Thinner films succumbed to failure at lower strains. These findings offer valuable insights into the design and optimization of molybdenum-based microelectronic devices and sensors, paving the way for further quantitative analysis to fully elucidate the intricate mechanisms at play.

This study measured 354 Jordanian children in six age group categories from 6 months to 9 years. The linear static measurements included the skeletal dimensions between body joints and the middle- and lower-body dimensions. The results showed negligible differences in seat height, seat depth, and seat width for males and females. However, desk surface height and elbow rest height differed for male and female children older than 5 years. These data can inform the design of various functional items such as tools, clothes, protective equipment, or furniture for Jordanian children.

This study examines copper thin films under tensile stress and their shape and percentage change in electrical resistance (PCER) as a function of applied strain. Copper films of 100 and 200 nm thickness were sputtered onto polyethylene terephthalate (PET) substrates and were then sequentially stretched to examine how film thickness affects strain-induced morphological changes and electrical resistance. A scanning electron microscope (SEM) was used to track crack patterns, and electrical resistance was monitored throughout tensile testing. Thinner films (100 nm) had quick crack initiation and propagation, leading to an increase in PCER under strain, while thicker films (200 nm) had more gradual morphological and electrical resistance changes. This differential reaction demonstrates the importance of film thickness in mechanical deformation and strain sensitivity, which could affect the design of flexible electronic devices that require mechanical durability and reliable electrical performance. These findings will help to optimize film thickness for stretchable sensors and wearable electronics to balance strain sensitivity and morphological degradation. This study will help designers and users of sensors, stretchable electronics, and other devices that require mechanical durability and electrical performance to understand the relationship between mechanical deformation and electrical properties in thin films. This paper aligns with the ninth goal of the United Nations Sustainable Development Goals, specifically Target 9.5: Enhance Research and Upgrade Industrial Technologies.

Cerebral palsy (CP) is a neurological disorder characterized by impaired movement, balance difficulties, abnormal muscle tone, and motor dysfunction resulting from brain damage during early developmental stages of birth. These impairments significantly influence a child’s ability to perform daily activities and lead an independent life. Therefore, providing appropriate assistive mobility devices is essential to enhance mobility, safety, and overall quality of life for children with CP. Walking aids are commonly used rehabilitation devices designed to support movement and promote independence. Many existing walking aids are not designed using anthropometric data representative of the geographical population for which they are intended, which may reduce their ergonomic suitability. This study addresses this limitation by developing a local anthropometric database for Jordanian children with CP aged 1–5 years. Anthropometric measurements were collected and analyzed to support ergonomic design requirements. Based on these measurements, dimensional requirements were established and translated into a conceptual computer-aided design (CAD) of an adjustable walking aid. The proposed conceptual design incorporates appropriate dimensional specifications derived from the collected anthropometric data to ensure comfort, stability, and safety. Jansen mechanism of motion is applied to the new design to promote children mobility. The proposed walking aid is intended to accommodate children with CP within the 1–5-year age group, facilitating improved mobility and supporting their participation in daily activities and rehabilitation programs.

Background: Designing toys, hand tools, furniture, and other ergonomic products requires careful consideration of users’ safety, comfort, and physical characteristics, particularly for elderly individuals. Anthropometric databases for older adults in developing countries remain limited, and human body measurements across multiple age groups are still insufficiently articulated. Objective: The primary objective of this study was to establish a comprehensive anthropometric database for the Jordanian elderly population and to systematically evaluate age- and gender-related variations in body dimensions for ergonomic, industrial, and elderly-oriented design applications. Methods: This study presents a comprehensive anthropometric dataset for 284 Jordanian elderly individuals equally divided between males and females. Participants were classified into four age groups: 60–65, 66–70, 71–75, and 76–80 years. A total of 25 precise static linear body measurements, including skeletal dimensions between body joints, were collected. These measurements included key indicators including but were not limited to stature, sitting height, shoulder height, eye height, and several other important anthropometric parameters. Afterwards, the collected data were compared with anthropometric data from other populations. Results: The results showed noticeable differences in multiple body dimensions across different populations. Variations were also observed among different age groups and genders within the studied population. The obtained dataset provides important anthropometric reference values for elderly-oriented ergonomic and industrial design applications. Conclusion: The anthropometric database developed in this study represents a valuable reference for the ergonomic design of functional products intended for elderly users in Jordan and other regions with similar demographic characteristics. The findings may support industries and designers in developing safer and more age-appropriate products while also emphasizing the importance of establishing additional comprehensive anthropometric databases for elderly populations worldwide.
