E-yarns also offer solutions to protect
the wellbeing of workers. The vibration-sensing yarn, which incorporates a small
microelectromechanical system able to
characterise vibration, was developed to
monitor vibration exposure of construction
workers. Construction workers come into
contact with significant levels of hand
transmitted vibration (HTVs) given the
prevalent use of power tools in that industry.
The ongoing research of the ATRG has
focussed on HTVs, which are known to
cause various musculoskeletal, neurological,
and vascular disorders such as hand-arm
vibration syndrome and carpal tunnel
syndrome. By integrating a yarn of this
type into a work glove, vibration levels
can be carefully recorded and a worker
warned if dangerous levels of vibration
New applications in this area will become
evident with the reducing size of small-scale sensors and other electronic devices.
The Advanced Textiles Research Group has
already begun experimenting with other
sensors types, such as moisture detection
and acoustic monitoring. An obvious next
step will be to develop a micro-controller
yarn that is capable of independently
controlling a series of embedded sensors
or output devices (like LEDs). It may only
be a few years before it is possible to create
garments with multiple embedding sensors
of different types, all controlled by an
