Your wife is never going to come out of the textile shop because she just can’t decide which colour to pick ? May be there is an invention just for her. This is a colour changing fabric developed by a team from the College of Optics and Photonics(CREOL) at the University of Central Florida. This cloth has microwires embedded in it that can change the colours of individual threads based on the amount of electrical current passing through them.

Sometime ago a similar technology of colour changing apparel did came out but this technology is not anything like that. That was more like a light up apparel that generated luminescence by embedded LEDs. But here each strand is covered by a thin piece of metal. As the amount of electrical current that runs through these wires changes, it’s temperature will vary. There are pigments embedded in the thread that reacts to such variations and changes its colour, and there you have your colour changing apparel. The good news is that you can do this all by your smart phone!
This technology is not too advanced as we speak. The clothes won’t change colours like magic. Each cloth can shift to only 2 or 4 colours. Also the colour changing fibres only align in a particular direction. So you can have stripes in horizontal or vertical direction, but not checks. Despite all the limitations, this invention has some undeniable advantage and might just become a popular fashion in coming years. After all, it will be great if you can just go and weave your own intricate patterns and make customised dress everyday.
