Smart sensor tights: Movement tracking of the lower limbs in football

This article presents a novel smart sensor garment with integrated miniaturized inertial measurements units (IMUs) that can be used to monitor lower body kinematics during daily training activities, without the need of extensive technical assistance throughout the measurements. The smart sensor tights enclose five ultra-light sensor modules that...

Associations between Hamstring Fatigue and Sprint Kinematics during a Simulated Football (Soccer) Match

PURPOSE: Neuromuscular fatigue is considered to be important in the etiology of hamstring strain injuries in football. Fatigue is assumed to lead to decreases in hamstring contractile strength and changes in sprinting kinematics, which would increase hamstring strain injury risk. Therefore, the aim was to examine the effects of football...

An inertial measurement unit based method to estimate hip and knee joint kinematics in team sport athletes on the field

Current athlete monitoring practice in team sports is mainly based on positional data measured by global positioning or local positioning systems. The disadvantage of these measurement systems is that they do not register lower extremity kinematics, which could be a useful measure for identifying injury-risk factors. Rapid development in...

A study of rheological limitations in rotary jet spinning of polymer nanofibers through modeling and experimentation

The recently popularized method of rotary jet spinning (RJS) or centrifugal spinning is investigated to evaluate the rheological limitations of polymer solutions and melts to optimal spinnability. The influence of Newtonian or non-Newtonian behavior of the polymer on spinnability is discussed. We observe that highly viscous polymers tend to...

Design capability in a software SME: Report from an embedded design innovation catalyst

<br/>Recent studies on the added value that design provides to firms has led to widespread interest amongst the business community to develop design. However, knowledge of how organizations of varying industry types actually make use of design to generate competitive advantages remains limited. This study investigates a small- to medium-sized...

A platform for secure, safe, and sustainable logistics

In the current society, logistics is faced with at least two big challenges. The first challenge considers safety and security measurements dealing with terrorism, smuggling, and related security accidents with a high societal impact. The second challenge is to meet sustainability requirements implying optimal use of resources and physical...

InP-based planar photonic crystals infiltrated with solid polymers and liquid crystals

The filling is reported of the air holes of an InP-based two-dimensional photonic crystal with solid polymer and withliquid crystal 5CB. The polymer filling is obtained by thermal polymerization of an infiltrated liquid monomer,trimethylolpropane triacrylate. The filling procedure for both the monomer and liquid crystal relies on the...

Two-dimensional photonic crystals from semiconductor material with polymer filled holes

Polymer filling of the air holes of indiumphosphide based two-dimensional photonic crystals is reported. The filling is performed by infiltration with a liquid monomer and solidification of the infill in situ by thermal polymerization. Complete hole filling is obtained with infiltration under ambient pressure. This conclusion is based both on...

InP-based two-dimensional photonic crystals filled with polymers

Polymer filling of the air holes of indium-phosphide-based two-dimensional photonic crystals is reported. After infiltration of the holes with a liquid monomer and solidification of the infill in situ by thermal polymerization, complete filling is proven using scanning electron microscopy. Optical transmission measurements of a filled photonic...
