Mobile Charging, via T-Shirts

  • PDF

In the future chargers will not only be part of our lives-- they will be part of our wardrobes, as Xiadong Li from the University of South Carolina proposes a means turning a cotton T-shirt into a source of electric power.

tshirt researchers Li and research partner Lihong Bao even provide the recipe on how to do exactly that. Get a cheap cotton T-shirt, soak it in a flouride solution, dry it, then bake it in an oxygen-free environment (in order to avoid charring or burning) at a high temperature.

The treatment transforms the cotton fibres making the T-shirt into an "activated carbon textile"-- a flexible material that acts as a double-layer capacitor (or supercapacitor) capable of storing electrical charges.

One can also enhance the electrode performance of the fabric further by coating individual carbonised fabric fibres with 1nm-thick manganese oxide "nanoflowers," creating a "stable, high-performing supercapacitor."

The final hybrid fabric not only stores electric charges-- according to researchers it is also resilient, as performance doesn't diminish by more than -5% even after thousands of charges.

"By stacking these supercapacitors up, we should be able to charge portable electronic devices such as cell phones," Li continues.

The process of activated carbon creation is both cheap and green, since other methods involve oil or other non-environmentally friendly chemicals as starting materials.

Maybe in the future we will not simply carry mobile chargers around-- we will be actually wearing them.

Wearable Displays Get SMART

 SMART Glasses

Wearable displays have often been referred to as "Head Mounted Displays" because of their bulky size and clunky appearance. Now Vuzix launches SMART Glasses Technology after years of internal development and a recent licensing deal with Nokia.

SMART Glasses Technology starts with a compact display engine capable of high contrast and brightness for outdoor use. The output is then relayed into a 1.4 mm thick polymer waveguide lens with input and output hologram structures on the surface which squeezes the light down the waveguide and then 2-dimensionally expands the image back into the user’s eye.
