Printed polymer gels for thermoelectric applications – Manuscript Published in Nature Communications

July 9, 2019 Uncategorized 3

All new printed gel electrolytes have been produced and published in Nature Communications for their use in temperature sensors based on tuneable thermoelectric properties. By adjustments in the gel composition, the materials can exhibit positive or negative Seebeck coefficient (a measure of a materials thermoelectric behaviour). Using screen printing techniques, the materials and devices can be easily manufactured in large area and at low cost production costs.

Here’s what lead author Dr Dan Zhao from Linkoping University had to say about her latest advance in thermoelectric technology:

‘Ionic thermoelectric materials attract little attention because it is difficult to directly harvest electric current from the ion thermodiffusion. However, the thermal voltage generated by these materials can be 100 times larger compared to the best reported electronic ones under same temperature difference, which makes them perfect candidates for heat/temperature sensing application. Moreover, the solution processability of the electrolytes also allows low-cost device manufacture. We believe that more and improved ionic thermoelectric materials will be developed in the future, and become more and more important in thermoelectric applications.’

Conceptualized.tech helped out with some figures to illustrate the screen-printing process and the image above for highlighting the materials used in the publications.

  1. You are so interesting! I don’t believe I have read anything like this before.

    So good to find another person with some unique
    thoughts on this topic. Really.. thank you for starting this up.
    This site is one thing that is required on the internet, someone with a bit of
    originality!

  2. This paragraph is genuinely a nice one it assists new the web visitors, who are wishing in favor of blogging.

  3. Definitely believe that which you said. Your favorite justification appeared to be on the internet
    the easiest thing to be aware of. I say to you, I definitely get irked while people think about
    worries that they just do not know about. You managed to hit the nail upon the
    top and defined out the whole thing without having side effect , people
    can take a signal. Will likely be back to get more.
    Thanks
