Found an interesting article :
Researchers have come up with another use for T-shirts: They can hold a charge like a capacitor.
A duo at the University of South Carolina, Professor Xiaodong Li and researcher Lihong Bao, managed
to convert a cheap t-shirt bought at a discount store into a wearable power source.
The t-shirt was soaked in flouride, dried and then baked in an oxygen-free room at a high temperature,
which changed the fabric from cellulose to activated carbon, without damaging the flexibility of the
material.
The result is that the fabric could be used as a capacitor, which can store an electrical charge. The
outcome was further enhanced by coating the fibres with manganese oxide, resulting in what Li called a
“stable, high-performing supercapacitor.”
The professor said that when these are stacked together they could be used to charge phones and tablet
computers, making clothing that little bit more useful than it currently is.
Of course, the potential downside is the unknown risks of wearing “charged” clothing. Electric shock is
one possibility that will need to be addressed, made even more problematic when considering what
might happen if the fabric gets wet. If these concerns were addressed, however, we might be plugging
into our t-shirts and jeans instead of the wall sockets.
I wonder where the limits to science and technology are... It sometimes scares me...
