Scientists at Harvard are claiming they’ve invented a brand new “wool-like” cloth that modifications form and, if I am being fully trustworthy, I am nonetheless making an attempt to wrap my head round it. First off, how the hell can a material have a reminiscence and, secondly, what does that even imply?

A publish on Harvard’s web site makes use of hair as a metaphor in an try and make clear. In the event you straighten your hair — and your hair will get moist within the rain — it will definitely goes again to its unique form, whether or not that is curly or wavy or no matter.

Apparently that is as a result of hair has “form reminiscence”.

Researchers on the Harvard John A. Paulson College of Engineering and Utilized Sciences (SEAS) have created a fibrous materials that does a lot the identical factor. The hope? This new materials might be utilized in garments to assist scale back waste within the trend business. The instance the Harvard article makes use of: a one-size all matches t-shirt that might mechanically shrink or increase to suit to an individual’s particular measurements. Or how about self-fitting bras or underwear?

The key is keratin, a protein present in hair and nails. The scientists took keratin from recycled wool and 3D printed the fabric into particular shapes. The above video exhibits one keratin sheet, 3D printed into an origami star, scrunched up, then positioned into water. Slowly it transforms again into one thing resembling its unique form.

“This makes the fabric appropriate for an enormous vary of purposes from textile to tissue engineering,” mentioned Luca Cera, a bioengineer at Harvard and creator on the paper. 

“With this mission, we have now proven that not solely can we recycle wool however we are able to construct issues out of the recycled wool which have by no means been imagined earlier than,” added Package Parker, the senior creator on the paper. “The implications for the sustainability of pure sources are clear. With recycled keratin protein, we are able to do exactly as a lot, or extra, than what has been achieved by shearing animals up to now and, in doing so, scale back the environmental influence of the textile and trend business.”
