Abstract Long‐duration spaceflight impacts essentially every system in the human body, resulting in multisystem deconditioning that might impair the health and performance of crewmembers, particularly on long‐duration exploration missions to Mars. In this review, we apply the sport science model of athlete monitoring, testing and training to astronauts;

Wrist Exoskeleton Device with a Novel Cable Drive Solution
This paper presents the design of a lower limb exoskeleton made for the purpose of wrist joint rehabilitation. The authors use the exoskeleton structure in order to cope with the user’s upper-limb kinematics and to provide motion to the wrist joint when the arm is in any possible spatial configuration. To reduce the inertia of the mechanical structure,

Abstract Prolonged exposure to weightlessness leads to loss of muscle and bone mass. Therefore, astronauts on board the International Space Station (ISS) currently perform mandatory daily exercises. ISS missions usually last 6 months, and future missions will become significantly longer when going, for example, to Mars.

A novel underactuated exoskeleton rehabilitation glove for hand flexion and extension training
In recent years, the number of stroke patients worldwide has been steadily increasing, with approximately 70% of survivors experiencing upper limb dysfunction, particularly severe impairment of fine motor skills in the hand. This limitation significantly

ABSTRACT Farmers frequently suffer from musculoskeletal disorders, particularly lower back pain (LBP), mainly due to occupational ergonomic factors such as repetitive stooping and lifting. This study proposes using an exoskeleton to reduce LBP risk by providing external torque to the hip joints.

Morphological and biomechanical adaptations of larval mandibles in Trichoptera (Insecta)
Mandible morphology differs between predators and grazers: predators show pointed incisors, grazers sharp edges and setae. Mechanical properties depend on cuticle tanning, not elemental reinforcement. Functional mandible types reflect feeding strategies, with predators specialized for prey capture and grazers for scraping and collecting.

AI‐Directed 3D Printing of Hierarchical Polyurethane Foams
Digitally guided direct ink writing, combined with AI‐generated design, enables the fabrication of hierarchical polyurethane foams with tunable multiscale porosity. This approach produces architected foams featuring interconnected open‐cell networks and tailored mechanical properties, advancing the development of adaptive, high‐performance materials ...

Two‐degree‐of‐freedom manipulator driven by PAM. ABSTRACT Rehabilitation robots are machines that allow patients to perform practice movements and ought to be sufficiently compliant for safe human interaction. Most robots today use hydraulic systems and continually rotating servo motors, making them less suitable for rehabilitation.

Sustainable bioceramics, biopolymers, and composites for bone applications: From bench to production
Abstract In response to environmental challenges and primary resource scarcity, sustainable approaches that rely on recycling and reusing waste materials are becoming highly valuable and appealing options in modern society. These strategies have started being applied in biomaterials science, too, leading to the advent of new synergies between ...
