“…Several studies have shown that using a corset can reduce tension and support the back, thereby preventing and reducing back pain (Myung et al, 2018;van Duijvenbode et al, 2008). Many investigations on the design of spinal corsets have been conducted, but most of them are to fix spinal disorders (Ali et al, 2020;Cooper et al, 2019). Meanwhile, the design of the spinal girdle specifically for brick-making industrial workers and its effectiveness has not been explored much.…”

Background: Doing activities that burden the back, such as bending over for a long time and lifting weights in the wrong position, can cause injury to the spine, leaving back pain. Thoracic Lumbar Sacral Orthosis Brace (TLSO Brace) is a tool used to support the spine so that it can prevent such an injury. Objective:This research aims to design and pilot a new ergonomic TLSO Brace that can be used to improve posture, reduce back pain and prevent back pain.Methods: This research is divided into several stages, namely designing, manufacturing, and testing.Results: The results show that the level of ergonomics is mainly in the Good category. The use of the TLSO Brace was proven effective in reducing back pain intensity (p0.0001); the average pain was reduced after 14 minutes. The results also found that all respondents who used the brace at work felt no back pain. It can be seen that the lordosis back arch becomes upright after using it, meaning the tool also improves posture.Conclusions: The ergonomic TLSO Brace has been created and can improve body posture, reduce pain intensity and prevent back pain from recurring.

“…Therefore, when creating an interaction model, it may be necessary to identify own material parameters for the macroscopic behavior. A common approach for the abdomen is to assume one linear material parameter per body region and varying body postures (Périé et al, 2004;Cooper et al, 2019;Bonnaire et al, 2020), but among others, Huang and Zheng (2015) state that one parameter pure elasticity theory is not sufficient to meet the hyperelastic properties of soft tissue (van Loocke et al, 2006).…”

Simulations of human-technology interaction in the context of product development require comprehensive knowledge of biomechanical in vivo behavior. To obtain this knowledge for the abdomen, we measured the continuous mechanical responses of the abdominal soft tissue of ten healthy participants in different lying positions anteriorly, laterally, and posteriorly under local compression depths of up to 30 mm. An experimental setup consisting of a mechatronic indenter with hemispherical tip and two time-of-flight (ToF) sensors for optical 3D displacement measurement of the surface was developed for this purpose. To account for the impact of muscle tone, experiments were conducted with both controlled activation and relaxation of the trunk muscles. Surface electromyography (sEMG) was used to monitor muscle activation levels. The obtained data sets comprise the continuous force-displacement data of six abdominal measurement regions, each synchronized with the local surface displacements resulting from the macro-indentation, and the bipolar sEMG signals at three key trunk muscles. We used inverse finite element analysis (FEA), to derive sets of nonlinear material parameters that numerically approximate the experimentally determined soft tissue behaviors. The physiological standard values obtained for all participants after data processing served as reference data. The mean stiffness of the abdomen was significantly different when the trunk muscles were activated or relaxed. No significant differences were found between the anterior-lateral measurement regions, with exception of those centered on the linea alba and centered on the muscle belly of the rectus abdominis below the intertubercular plane. The shapes and areas of deformation of the skin depended on the region and muscle activity. Using the hyperelastic Ogden model, we identified unique material parameter sets for all regions. Our findings confirmed that, in addition to the indenter force-displacement data, knowledge about tissue deformation is necessary to reliably determine unique material parameter sets using inverse FEA. The presented results can be used for finite element (FE) models of the abdomen, for example, in the context of orthopedic or biomedical product developments.

3D Printing or Additive Manufacturing is one of a novel method in manufacturing of materials with increased accuracy of manufacturing in terms of complexity in parts, design of aerospace and defense parts, light-weighting, etc., This manufacturing method involves layer-by-layer printing or deposition of materials or metals into the perfectly aligned especially in corners, edges and in most complex designs. The design process mostly involved software so that production cost could be estimated in the design stage itself. Additive Manufacturing is one of the most promising approach for small and low-volume productions. The filament used for the process is prominent to the designer, along with the various printing processes. Recent modern printing techniques involve multiple nozzles, whereas designers can use multiple materials on single printing. The use of multi-material in a single part enables the manufacturer to rapidly produce products which have specific applications. This chapter discusses about various multi-material with different mechanical properties that can be used for structural applications through different printing technologies on various precious applications. This technology is quickly adopted by even small-scale industries in recent times.
