Editors’ Choice—Development of Screen-Printed Flexible Multi-Level Microfluidic Devices with Integrated Conductive Nanocomposite Polymer Electrodes on Textiles

Bonnie Gray, a professor at Simon Fraser University’s school of engineering science, was inspired by the city of Vancouver in British Columbia in her latest work.

“Vancouver is well-known for its technical clothing, and I have a lot of friends in the film industry who work in costume design. A combination of these influences and my own engineering background caused me to look further into integrating clothing with technology. That’s how I went on to become involved in developing screen-printed flexible multi-level microfluidic devices on textiles,” said Gray, which led to the fruition of her and lead author Daehan Chung‘s research paper, “Development of Screen-Printed Flexible Multi-Level Microfluidic Devices with Integrated Conductive Nanocomposite Polymer Electrodes on Textiles.”

In their open access paper, published in the Journal of The Electrochemical Society, the pair “present a flexible plastisol-based microfluidic process integrated with conductive nanoparticle composite polymer (C-NCP) electrodes for flexible active microfluidic devices on textile substrates.”

According to Gray, flexible and wearable microfluidic devices are among the newest wearable devices for applications in health monitoring, drug delivery systems, and bio-signal sensing. (more…)

Clothes That Monitor, Transmit Biomedical Info

We’ve hear about smartphones and “smart cars,” and even such recent developments as the smart highway – but what about a smart textile?

Researchers from Université Laval’s Faculty of Science and Engineering and Centre for Optics, Photonics and Lasers are well on their way to developing clothes that can monitor and transmit biomedical information on wearers.

By using sensor technology and wireless networks, this smart textile will be able to track and transmit this medical information – which has the potential to be extremely beneficial for people suffering from chronic disease, firemen and police offers, and people who are elderly.
