Was, wenn Ihr Holzboden Ihr Zuhause mit Strom versorgt?

Wissenschaftler haben herausgefunden, wie man Holzstücke dazu bringt, eine Ladung zu erzeugen, sobald man Druck auf sie ausübt. Das könnte die Effizienz von Gebäuden verändern.

In einem Video von Schweizer Forschern tritt jemand immer wieder auf ein kleines Quadrat am Holzboden. Dieses Quadrat ist mit einer Glühbirne verkabelt und bei jedem Schritt flackert die Glühbirne. Allein durch das Betreten des Holzbodens hat die Person also Strom erzeugt.  

Der triboelektrische Effekt

Dies funktioniert durch den sogenannten triboelektrischen Effekt, der eine Möglichkeit darstellt, Elektrizität zu erzeugen, indem Elektronen von einem Material auf ein anderes übertragen werden. Normalerweise passiert das durch die Art und Weise, wie diese Materialien aneinander reiben (denken Sie an statische Elektrizität). Obwohl die Nutzung dieses Effekts nicht ganz neu ist – triboelektrische Nanogeneratoren wurden bereits in Bodenbelägen und sogar in tragbaren Stoffen verwendet –, haben die Forscher vom Labor für Holzwerkstoffe der ETH Zürich und der Eidgenössischen Materialprüfungs- und Forschungsanstalt Dübendorf auch ihren Generator aus Holz hergestellt. Und dabei haben sie natürlich ein nachhaltiges Material verwendet, das Teil intelligenter Gebäude der Zukunft werden könnte. Ihre Arbeit zu ihrem Nanogenerator haben die Forscher in der Fachzeitschrift Matter veröffentlicht.

Die meisten triboelektrischen Nanogeneratoren verwenden synthetische Materialien wie Teflon oder Silikon, um ihren Strom zu leiten. Diese werden als „triboaktive“ Materialien bezeichnet. Holz ist dafür kein großartiges Material, da es im Grunde neutral ist – es zieht weder Elektronen an noch verliert es. Ein triboelektrischer Nanogenerator muss jeweils ein Material verwenden, um eine Ladung zu erzeugen. Um dies zu umgehen, veränderten die Forscher die triboelektrischen Eigenschaften des Holzes, indem sie ein Stück mit einem Silikon und das andere mit Nanokristallen namens ZIF-8 beschichteten, die Metallionen und organische Moleküle enthalten.

Holz und Schnittrichtung hat Einfluss auf Stromerzeugung

Sie testeten verschiedene Hölzer und sogar verschiedene Holzschnitte, da die Schnittrichtung des Holzes einen Einfluss auf die Stromerzeugung hatte. Am besten schnitt die radial geschnittene Fichte ab. Da sie Holz als „Gerüst“ für diese triboaktiven Materialien verwendeten, konnten sie geringere Teile an synthetischen Materialien verwenden, sagt Guido Panzarasa, leitender Autor der Studie und Gruppenleiter im Wood Materials Science Laboratory. „Wir haben nicht nur Erkenntnisse darüber gewonnen, welche Rolle Holz in einem triboelektrischen Generator spielen kann, sondern wir haben auch einen Nanogenerator hergestellt, der hauptsächlich aus Holz besteht“, sagt er im Vergleich zu früheren Nanogeneratoren, die zu einem weitaus höheren Teil aus diesen synthetischen Materialien bestehen.

Diese Forschung steht noch am Anfang. Der von ihnen hergestellte Prototyp, der kleiner als ein Blatt Papier war, konnte genug Strom erzeugen, um eine LED-Lampe und eine kleine Elektronik wie einen Taschenrechner anzutreiben, aber es ist schwer abzuschätzen, ob auch genügend Energie erzeugt werden kann, um ein Stockwerk in einem Bürohaus zu versorgen. Hierbei spielen natürlich viele Faktoren eine Rolle – zum Beispiel wie viele Leute darauf laufen und wie oft, wie groß der Raum ist, wie viele Geräte mit Strom versorgt werden müssen usw.

„Die Idee dahinter ist, ein Material umzuwandeln, das gleichzeitig natürlich, erneuerbar, nachhaltig und CO2-speichernd ist und dieses zu verwenden, um die Energieeffizienz von Gebäuden zu steigern.“, so Panzarasa.

    on my end? I’ll check back later on and see if the problem still exists.

  59. We are a group of volunteers and opening a new scheme
    in our community. Your web site provided us with valuable
    info to work on. You’ve done a formidable job and our entire community will be grateful to you.

  60. Hello there! This post couldn’t be written any better! Reading through this post reminds me of my good old room mate!
    He always kept chatting about this. I will forward this post
    to him. Pretty sure he will have a good read.
    Thank you for sharing!

  61. Great website. Plenty of helpful info here. I am sending it to a few
    pals ans additionally sharing in delicious. And obviously,
    thank you to your sweat!

  62. Howdy! This post could not be written any better! Reading this post reminds me of my
    previous room mate! He always kept chatting about this.
    I will forward this page to him. Pretty sure he will have a good read.
    Many thanks for sharing!

  63. For hottest information you have to pay a visit internet and
    on world-wide-web I found this site as a best web page for hottest updates.

  64. Awesome blog you have here but I was wanting to know if you knew of
    any message boards that cover the same topics talked about here?
    I’d really love to be a part of online community where I can get responses
    from other experienced people that share the same interest.
    If you have any suggestions, please let me know. Bless you!

  65. Definitely believe that which you stated.
    Your favorite justification appeared to be at the internet the easiest
    factor to understand of. I say to you, I certainly get irked
    while other folks consider worries that they plainly don’t recognise about.
    You controlled to hit the nail upon the top as well as defined out the whole thing with no need side effect , people could take a signal.
    Will likely be back to get more. Thank you

  66. Good day! I know this is somewhat off topic but I was wondering if you knew
    where I could locate a captcha plugin for my comment form?
    I’m using the same blog platform as yours
    and I’m having problems finding one? Thanks a lot!

  67. I was wondering if you ever thought of changing the layout of your blog?
    Its very well written; I love what youve got to
    say. But maybe you could a little more in the way of content so people could
    connect with it better. Youve got an awful lot of text for only having one or 2 images.

    Maybe you could space it out better?

  68. Hi there just wanted to give you a quick heads
    up and let you know a few of the pictures aren’t loading properly.
    I’m not sure why but I think its a linking issue.
    I’ve tried it in two different browsers and both show the same
    outcome.

    just wonderful!

  75. Hi would you mind stating which blog platform you’re using?
    I’m going to start my own blog in the near future but I’m having a
    hard time making a decision between BlogEngine/Wordpress/B2evolution and
    Drupal. The reason I ask is because your design and style seems different then most
    blogs and I’m looking for something unique. P.S Sorry for getting off-topic but I had to ask!

  76. Excellent site you have here.. It’s difficult to find excellent writing like yours these days.
    I really appreciate people like you! Take care!!

    be looking for. You’ve ended my 4 day long hunt! God Bless you man. Have
    a great day. Bye

  79. Thanks for one’s marvelous posting! I truly enjoyed reading it, you may be a great author.I
    will be sure to bookmark your blog and will often come back in the foreseeable future.
    I want to encourage that you continue your great posts,
    have a nice weekend!

  80. Hello to every one, for the reason that I am genuinely eager of reading
