Parametric Modeling of a Generic Active Lumbar Exoskeleton for Ergonomic Impact Assessment
Published on 2025-02-22 by Manuel Pérez-Soto, Javier Marín, José J. Marín @MDPI
Abstract: Companies increasingly implement exoskeletons in their production lines to reduce musculoskeletal disorders. Studies have been conducted on the general ergonomic effects of exoskeletons in production environments; however, it remains challenging to predict the biomechanical effects these devices may have in specific jobs. This article proposes the parametric modeling of an active lumbar exoskeleton using the Forces ergonomic method, which calculates the ergonomic risk using motion capture in the[...]
Our summary: Study proposes parametric modeling of active lumbar exoskeleton using Forces method for ergonomic risk assessment in workplace.

Fabrication of PVTF Electroactive Coatings on PEEK Implant to Provide Surface Potential for Enhancing Osteogenesis
Published on 2025-02-22 by Aotian Yee, Xin Xin, Haoqing Liu, Lanxue Ma, Kui Cheng @MDPI
Abstract: Polyetheretherketone (PEEK) has gained significant attention in biomedical applications due to its excellent mechanical properties and biocompatibility. In this work, the fabrication of electroactive poly(vinylidenefluoride-co-trifluoroethylene) (PVTF) coatings on PEEK surfaces to enhance osteogenesis is explored. PEEK substrates were prepared with different surface treatments to optimize adhesion, followed by PVTF coating through drop-casting and polarization. Morphological, chemical, and therm[...]
Our summary: Fabrication of PVTF Electroactive Coatings on PEEK Implant enhances osteogenesis with improved biocompatibility and adhesion, achieving peak piezoelectric coefficient.

Assessment of the Mechanical Properties of Soft Tissue Phantoms Using Impact Analysis
Published on 2025-02-22 by Arthur Bouffandeau, Anne-Sophie Poudrel, Chloé Brossier, Giuseppe Rosi, Vu-Hieu Nguyen, Charles-Henri Flouzat-Lachaniette, Jean-Paul Meningaud, Guillaume Haïat @MDPI
Abstract: Skin physiopathological conditions have a strong influence on its biomechanical properties. However, it remains difficult to accurately assess the surface stiffness of soft tissues. The aim of this study was to evaluate the performances of an impact-based analysis method (IBAM) and to compare them with those of an existing digital palpation device, MyotonPro®. The IBAM is based on the impact of an instrumented hammer equipped with a force sensor on a cylindrical punch in contact with[...]
Our summary: Evaluation of impact-based analysis method (IBAM) for assessing mechanical properties of soft tissue phantoms compared to MyotonPro, paving the way for non-invasive skin biomechanical measurements.

A Case Study of the Gran Chaco in Central Argentina
Published on 2025-02-21 by Francisco G. Alaggia, Michele Innangi, Laura Cavallero, Dardo Rubén López, Federica Pontieri, Flavio Marzialetti, Ramon Riera-Tatché, Paolo Gamba, Maria Laura Carranza @MDPI
Abstract: Anthropogenic alteration of tropical and subtropical forests is a major driver of biodiversity loss; notably, the Chaco Forest, which is the largest dry forest in the Americas, is among the most impacted regions. Sustainable forest management, a key objective of the UN’s 15th Sustainable Development Goal (SDG), underscores the need for advanced monitoring tools. This study integrates Sentinel-2 remote sensing (RS) spectral indices with field data to analyze forests under varying ma[...]
Our summary: This case study analyzes the anthropogenic alteration of the Gran Chaco in Central Argentina using Sentinel-2 remote sensing spectral indices and field data. The study highlights the effectiveness of using spectral indices such as BI, NDWIGao, and MCARISent to differentiate forest stands by conservation status and structural alteration. The integrated approach proves to be a reliable tool for monitoring forest health and supporting progress towards sustainable development goals.

Enhanced Compressive Properties of Additively Manufactured Ti-6Al-4V Gradient Lattice Structures
Published on 2025-02-21 by Zhengjie Guo, Yuting Ma, Tayyeb Ali, Yi Yang, Juan Hou, Shujun Li, Hao Wang @MDPI
Abstract: Lattice structures are widely used in the aerospace and biomedical fields, due to their lightweight, high specific strength, large specific surface area, good biocompatibility, etc. However, the balancing of the weight and the mechanical properties remains a challenge in designing lattice structures. Combining experiments and simulations, the present work first designs and evaluates the mechanical properties of uniform and gradient topology-optimized Ti-6Al-4V lattices with the same overall poro[...]
Our summary: Enhanced compressive properties of Ti-6Al-4V lattice structures with gradient topology optimization, fabricated using laser powder bed fusion technology, show improved performance compared to uniform lattice structures.

Abstract: This study investigated the effects of plasma electrolytic oxidation (PEO) treatment in a Ca- and P-rich electrolyte on the surface of the Ti-6Al-4V alloy with distinct α/β phase proportions previously induced by heat treatments. The results revealed that the α/β phase proportions were successfully altered by the heat treatment temperatures, forming α phase plates surrounded by β phase precipitates. PEO-treated samp[...]
