There has been much in the recent news about harnessing power from the sweat you generate from working out. Testing is being conducted with sensors placed in a temporary tattoo – or even inside your underwear – which could pull electrons from sweat (lactic acid), producing a weak electrical charge which could power small electronic devices. The tiny, cheap biobatteries can harvest enough power to power wristwatches and LED lights.
Professor Joseph Wang and his research team at University of California, San Diego imprinted a flexible lactate sensor onto temporary tattoo paper. The sensor contained an enzyme that strips electrons from lactate, generating a weak electrical current.
What a great motivator – it may inspire you to workout harder at the gym – the more sweat you generate, the more battery time you could have on your cell phone!
There has been a lot of discussion about eco-friendly packaging. Part of the challenge is making it durable enough for transport, safe enough that it won’t affect the contents, and bio-degradable or otherwise recyclable. Kind of a tall order, isn’t it? Plus you want any package to be reasonably attractive to catch a buyer’s eye and make them drool over your product from the outside, before they actually use it, right?
Here are some notes from various sources about the ways that packaging is becoming more ‘green’- and the why’s behind this trend. Maybe you have some ideas of your own that you can bring to market and make a contribution in helping to cut down on landfill…links for the companies are within each article – perhaps your new career lies with one of these corporations!
“Consumers are increasingly expecting eco-friendly packaging, says SIG Combibloc, as it sets ‘ambitious targets’ to reduce its environmental impact”
And here’s an article about packaging problems you’ll want to avoid repeating…
With so many industries racing to find the next great “green” solution, it’s no wonder that we’ve been hearing about some pretty fantastic advances in the textile industry.
Like the recently blogged air cleaning buildings, textiles are following closely behind. From catalytic clothing that actually cleans the air surrounding the person wearing it to self-cleaning cashmere, this is something that appeals to the masses. After all, we all wear clothing, right?
The secret ingredient of this new generation of clothing is titanium dioxide, typically found in sunscreens.
Most people wouldn’t consider a denim kilt or a ball gown essential tools for mitigating climate change, but that’s exactly what Helen Storey, a professor at University of the Arts, and Tony Ryan, a professor at University of Sheffield, have created in a series of textiles capable of sponging greenhouse gases from the surrounding air. Learn more about catalytic clothing.
And now, how about that self-cleaning cashmere:
Dr. Walid Daoud, and his research team at City University of Hong Kong claim that by coating cashmere in anatase titanium dioxide and exposing it to 24 hours of light, stains will break down—no water required. More study is needed to ensure the safety of wearing this chemical. Still, the idea is intriguing, particularly for stain-prone cashmere fans.
“The breakthrough is that, for the first time, cashmere fibers have been enabled to harvest light to clean themselves. This implies substantial savings on energy, water and petroleum-derived chemicals used in the conventional cleaning process, as well as pricey trips to the dry cleaner,” Dr Daoud explained.
We may soon be making choices such as catalytic or not catalytic in addition to whether we look better in blue or green, don’t you think?
Contributing to a more sustainable, green world certainly takes a lot of different skill sets. Do you have expertise with this technology?
