Psychotextiles could be the next big thing in fabrics

-Professor George Stylios and Meixuan Chen.

We know that shapes and colour produce certain emotions; this study looks at how visual characteristics, such as patterns, produce the same emotions in the majority of the population. And if so, can we manipulate them to change our state of mind? Our insights into colours and shapes come mainly from neuroscientists looking for ways to treat people with psychiatric problems such as depression and schizophrenia.We conducted two studies to identify if patterns had an emotional effect on people.

 

Medical compression has the power to save lives.

-Dr Lisa Macintyre

Laplace law (Pressure = tension ÷ radius) was proved for large circumferences, unproved for smaller circumferences but significant evidence exists that resistive ink pressure sensors lack sensitivity if bent on small radius of curvature.

It is likely therefore, that the difference in measured pressures was due to a deficiency of the sensor rather than two physical laws describing the pressure relationship.

Anti-embolism stockings.

  • I first thought about anti-embolism stockings when I was fitted with them during a stay in hospital.
  • Anti-embolism stockings are used to prevent venous thromboembolism, which is the collective term for Deep Vein Thrombosis DVT and pulmonary embolism.
  • DVT are blood clots occurring in the deep veins of the legs. They typically develop when people are immobile.
  • Pulmonary embolism occurs when part of a DVT breaks off and blocks an artery, this can be fatal.
  • Venous thromboembolism is responsible for 10% of hospital deaths and 25 000 deaths/year in England alone.
  • Therefore, anti-embolism stockings (and blood thinning drugs) are issued to patients for a wide range of conditions at significant cost to NHS.
  • They work by delivering graduated pressure to the legs, this is high pressure at ankle reducing to low pressure at the upper thigh.
  • The Sigel pressure profile has been shown to be most effective – this is 18mmHg at ankle, 14mmHg at the calf and 8mmHg at upper thigh.
  • The Lancet … reported the multi-centre, randomised clinical trial (CLOTS trial) evaluating efficacy of anti-embolism stockings (graduated compression stockings) for DVT prevention in stroke patients.

Surface modification of fibres and fabrics for improved impact energy absorption.

-Dr Danmei Sun

Looks at the drawbacks of current commercial available body armour materials where this research concept was built up.

There are research results from two approaches. One is practice based which is surface modification of body armour material using plasma technology. The other Finite Element modelling to show you some of the predicted results.

Both the practice and FE simulation confirm that plasma treatment could be an effective approach in the improvement of ballistic performance of current used body armour materials.
