    Anthropos and Metrikos both mean "human" in Greek, which is where the term anthropometry comes from. Anthropometry is employed in a variety of fields, including apparel and textile design. For anthropometric evaluations, a current, thorough, and community-specific anthropometric normative-reference standard is necessary. In health care, ergonomic design is utilised to reduce pain and illness. Misalignments between humans and machines result in pain, accidents, biomechanical stress, tiredness, and musculoskeletal injuries. Designing for the anthropometrics of end users improves long-term viability. The human body comes in a wide range of sizes and shapes. Manual measurement and 3D scanning procedures, on the other hand, are inefficient and expensive, making precise body measurements difficult. This is especially true for head-worn medical devices. Manual measurement and 3D scanning are inefficient and expensive, making precise body measurements difficult. Grip strength and force were determined using hand measurements. Anthropometric parameter estimate is more precise when a 3D model is used to boost pinnae features. While numerous anatomical features have been gathered to aid in the ergonomic design of wearable devices, there is still a lot more work to be done. In three dimensions, the segment masses and torso Centre of Mass (COM) may be calculated. Researchers tracking mobility would benefit greatly from the ability to locate the body COM using a weighted sum of segment masses. Design features such as comfort and usefulness are crucial. Ergonomic characteristics like taller seats with front slopes and saddle chairs encourage good posture, movement, and alternation. In the creation of wearable technologies, using outdated anthropometric reference standards may be insufficient. This review discuses common issues related to anthropometry in engineering which includes the human body, anthropometric parameters, anthropometric measurements, the force plate method, ergonomic design, and body dimension. The goal is to give a broad overview of the subject.

    Motion capture was employed by Eadweard Muybridge and Etienne-Jules Marey. Industry standard for computing joint kinematics is motion capture. Kinematic analysis is a technique used in biomechanics and mechanical engineering to quantify stiff body motion. A joint moment can be computed in one of two ways: bottom-up or top-down. Joint moments measure muscle and joint tension indirectly. Researchers predicted joint moments using kinematic-based characteristics and machine learning outside of the biomechanics lab.Ankle osteoarthritis causes significant biomechanical issues in the foot and lower leg. Patients' 3D multi-segment kinematic foot models were studied. The technique used is Openpose, which recognises the human body from a single photograph.Falling fear is linked to decreased activity, despondency, and anxiety in the elderly. They adopt a hip approach to manage their GRFs and balance. The lateral ankle technique corrects minor foot placement problems by swiftly moving the pressure point. Angular momentum is affected by foot placement and ground reaction forces. Changing the body's centre of mass along a curved trajectory implies large changes in both ground reaction force impulses and ground reaction force.Lens stiffness and a ciliary muscle anterior/inward displacement produce presbyopia. By 55, the majority of folks have lost their ability to accommodate. Cataracts become common around this time, reaching over 70% by 75. The circumferential and meridional stiffnesses rose with anisotropy from pole to equator, but dropped with distance. The Holzapfel model accurately fits the data from inflation and uniaxial mechanical tests.Anatomical motions of the femur during knee flexion were examined. The data revealed morphological and physiological knee kinematic characteristics. The data led to several hypotheses about axial femoral condyle rotation. This review discusses lower limbs, foot positioning, lens capsule, femoral condyle, muscle activation, collagen fibre, knee joint, and walking speed. The purpose is to provide a general overview on the subject matter.

    Work-related musculoskeletal disorders (WMSDs) are one of the most common occupational ailments in recent decades, significantly limiting people's daily lives. Globally, WMSDs are the major cause of employee pain, impairment, absenteeism, reduced productivity, and large financial costs. WRMSDs are illnesses that develop over time because of long-term occupational exposure to varying-intensity loads. WRMSDs are produced by discomfort or injury to the muscles and bones of the upper limbs because of activity. Low-extremity illnesses, like upper-limb diseases, may be just as dangerous, There is a high prevalence of neck and upper extremity problems among computer users. Upper extremities diseases were more common in older personnel. The physiological outcome of prolonged, repetitive, or repeating muscle contractions with insufficient recovery is localised muscular fatigue (WMSDs). Muscle tiredness has a substantial impact on occupational task performance, hence preventing it is crucial. The key challenge in ergonomics is to create work that avoids WMSDs while retaining high levels of output quality and productivity. Uncomfortable postures are commonly recognised as a major contributor of MSD among construction workers. Because of their linearity, ergonomic metrics can be incorporated into assembly line design models. They can also be utilised to take use of efficient solution methods established for optimal line design which are beneficial in the assembly line industry. Real-time risk assessment for work-related musculoskeletal disorders (MSDs) has proven to be challenging to research. Working at a fast speed and performing repetitive activities, as well as maintaining non-neutral body postures, are all physical risk factors for WMSDs. This review discuses common issue related to WMSDs which includes upper extremity, upper limbs, carpal tunnel syndrome, awkward postures, muscle activity, muscle fatigue, assembly line and risk assessment. The aim is to provide an overview of the problems related to the subject matter.

    The banana fibre is part of research aimed at creating materials for weaving bomb blankets. To determine whether plain and intra-ply woven banana fibre designs are feasible and effective in enhancing blast resistance, the primary purpose of this research is to analyse the practicability and efficiency of these designs. The method begins with extracting banana fibres, followed by applying an alkali treatment to enhance the mechanical properties of the fibres, and finally concludes with weaving the fibres into plain and intra-ply patterns. The scanning electron microscopy (SEM) technique was utilized to analyse the surface morphology and assess any damage that occurred as a result of the blast. Based on the findings, it was shown that plain woven banana fibres demonstrated greater tensile strength (7.39 MPa) and energy absorption (11,772 J) compared to intra-ply woven patterns. The SEM analysis indicated that plain woven fibres had a lower number of surface flaws, highlighting their increased resistance to explosive forces. In conclusion, plain woven banana fibres have significant potential to serve as an alternative to synthetic materials for blast-resistant applications. This alternative is not only cost-effective but also environmentally friendly. Therefore, it is possible for them to meet standards in terms of both environmental sustainability and security.
