Development of a Passive Back-Support Exoskeleton Mimicking Human Spine Motion for Multi-Posture Assistance in Occupational Tasks

Biomimetics
Passive back-support exoskeletons commonly employ elastic components to assist users during dynamic tasks. However, these designs are ineffective in providing sustained assistance for prolonged static bending postures, such as those required in surgery ...

Active Sticks: a New Dimension in Controller Design [PDF]

, 1984
A smart stick controller was built which actively produces a force to interact with the subject's hand and to aid in tracking. When the human tracks in this situation, the man-machine system can be viewed as the combination of two closed loop feedback ...

Active Learning‐Accelerated Discovery of Fibrous Hydrogels with Tissue‐Mimetic Viscoelasticity

Advanced Functional Materials, EarlyView.
Active learning accelerates the design of fibrous hydrogels that mimic the viscoelasticity of native tissues. By integrating multi‐objective optimization and closed‐loop experimentation, this approach efficiently identifies optimal formulations from thousands of possibilities and decouples elasticity and viscosity. The resulting hydrogels offer tunable

A review of recent perspectives on biomechanical risk factors associated with anterior cruciate ligament injury [PDF]

, 2014
There is considerable evidence to support a number of biomechanical risk factors associated with non-contact anterior cruciate ligament (ACL) injury. This paper aimed to review these biomechanical risk factors and highlight future directions relating to ...

A Novel Decellularized Fibrocartilage Graft Promotes Tympanic Membrane Repair

Advanced Healthcare Materials, EarlyView.
An off‐the‐shelf decellularized porcine meniscus fibrocartilage graft (MEND) is engineered for pediatric tympanoplasty. Featuring a microchannel architecture that promotes host cell invasion, MEND rapidly closes tympanic membrane perforations and fully remodels in vivo, outperforming fascia and matching cartilage grafts while avoiding donor‐site ...
