Responsive Polyelectrolyte Brushes in Applications: Functions, Stimuli, and Design Considerations
Advanced Materials, EarlyView.With advances in the synthesis of polyelectrolyte brushes, these coatings of surface‐grafted chains find uses in an increasing number of applications. This review summarizes three core aspects of these brushes: how they introduce functionality to surfaces; how external stimuli influence their properties; and what practical considerations should be ...

Introduction to Prosthetic Limbs [PDF]
, 2015 Approximately 2 million people in the Unites States alone have had an amputation, and many of these people use a prosthetic limb daily. The prosthetic limb, which began as a primitive device, is now a highly sophisticated piece of technology.

Advanced Materials, EarlyView.An ideal implant should mimic native tissues such that it can integrate, sense, heal, and continue to function, i.e., be autonomous. Although early, there are good steps taken in this way, e.g., the development of stimuli‐responsive, self‐powering, self‐actuating, self‐healing, self‐regenerating, and self‐aware implants.

Stiffness Analysis of Above Knee Prosthesis
International Journal of Intelligent Systems and Applications in Engineering, 2019 While a healthy human walks, his or her legs mutually perform good repeatability with high accuracy. This provides an esthetical movement and balance. People with above knee prosthesis want to perform walking as esthetical as a healthy human. Therefore, to achieve a healthy walking, the above knee prosthesis must provide a good stiffness performance ...

Interactions Between Transfemoral Amputees and a Powered Knee Prosthesis During Load Carriage
Scientific Reports, 2017 Machines and humans become mechanically coupled when lower limb amputees walk with powered prostheses, but these two control systems differ in adaptability. We know little about how they interact when faced with real-world physical demands (e.g. carrying

Lubrication model of a knee prosthesis, with non newtonian fluid and porous rough material [PDF]
, 2009 Tibial component of knee prostheses, made of ultra high molecular weight polyethylene (UHMWPE), experiences a high degree of wear and may be expected to last twelve years on average.

Advanced Materials Interfaces, EarlyView.Titanium (Ti) and bismuth (Bi) are selected as alloying elements for the preparation of the Ti‐Bi binary alloy system. Biofilm formation is found to be inhibited by bismuth through the disruption of sulfur metabolism and redox homeostasis, as well as through the direct downregulation of biofilm‐associated proteins.

Advanced Materials Technologies, EarlyView.A highly sensitive crack‐based piezoresistive strain sensor is developed using a biaxially pre‐stretched multi‐walled carbon nanotubes/Ecoflex composite and integrated with auxetic metamaterials. Biaxial pre‐stretching improves the sensitivity by 56% compared to the uniaxially pre‐stretched strain sensor.
