Sensors in clothes to monitor vital signs for illness and warn on exposure to dangerous chemicals
March 18, 2013 // Paul Buckley
Peratech is working with the London College of Fashion, University of the Arts London to develop wearable electronics that use Peratech’s award-winning QTC sensors.
The three and a half year PhD research project is funded by an EPSRC ICASE award to explore the needs base and applications for wearable technology bringing together the expertise of industry and academe in a highly creative way.
“We are very excited to be involved in this project,” said David Lussey, Peratech’s CTO. “Our QTC materials have already been used to provide switches in clothing for a number of years and so we know that it can withstand the rigors of being worn and washed. This project combines technology, design and user needs to work out how this growing area of wearable technology can be developed.”
The core of QTC technology is that QTC materials change their resistance when a force is applied such as pressure. Printing QTC inks on to textiles enables simple on/off switches to be created but, more interestingly, because the resistance changes proportionally to the amount of force applied, areas of the cloth can become touch sensitive or can be made to recognise pressure inputs.
“There are already glasses that provide computer displays,” explained David Lussey, “but they lack a simple way to input and interact with them. With our technology, you could print a keyboard onto a sleeve or onto the back of a glove and link it via Bluetooth to the glasses. Or even a rectangle of touch sensitive QTC material to act as a touchpad and respond to multi-touch gesture inputs of pinch, stretch, flick, etc. which are familiar from smartphones and tablets.”
Apart from being touch sensitive, QTC materials can also detect the presence of volatile organic compounds (VOCs). Its printable QTC E-nose sensors work by the QTC material expanding in the presence of VOCs which changes the resistance of the QTC material giving very rapid response and recover times along with a high level of sensitivity. Different formulations can be made according to the specific VOC to be detected so that low cost warning sensors and the associated electronics can be printed onto textiles to provide clothing that monitors the wearer for signs of illness, fatigue or exposure to dangerous chemicals.
“Apart from the obvious military applications of remote monitoring of personnel for stress and chemical attack, these sensors could be incorporated into clothing for everyday health monitoring as certain VOCs can be early indicators of health issues,” explained David Lussey. “What is exciting is that the ability to print active and passive components is really taking off so that these combine with our QTC technology so that everything needed to print complete electronic circuits can be done at the same time directly onto flexible substrates such as films, papers and textiles.”

Internet of Things (IoT) manufacturer Ciseco has launched the Raspberry Pi ‘Wireless Inventors Kit’ (RasWIK), featuring 88 pieces to provide everything a Pi owner needs to follow a series of step-by-step projects or to create their own wireless devices, without the need for configuration or even writing code.
RasWIK has been designed to be highly accessible, demystifying the dark art of wireless and enabling anyone with basic computing skills to begin building wireless devices with a Raspberry Pi. You can create anything from a simple traffic light, to a battery monitor, or even a temperature gauge that sends data to the Xively IoT cloud so billions can access the data.This month, Ciseco is giving away twelve Raspberry Pi Wireless Inventors kits, worth £49.99 each for EETimes Europe's readers to win.
And the winners are...
In our previous reader offer, Farsens was giving away five kits for EEtimes Europe readers to evaluate its FenixVortex, Kineo and X1 wireless, battery free sensor tags.
Lucky winners include Mr A. Neil from the UK, Mr. E. Delvaux from Belgium, Mr Lengal from the Czech Republic, Mr H. Bijlsma from the Netherlands, and Mr G. Pfaff from Germany. All should be receiving their packages soon. Lets wish them some interesting findings with their projects.
