Clothes can make phone calls, play music, dial your pal’s number, keep you warm during cold weather and operate your computer?

This is not a fantasy. A British company, called Electrotextiles, has created a wide range of clothes — clothes that have minds of their own! Scientists, working for the company, have invented a kind of fabric that can be blended(混合) with flexible electronic materials to create intelligent clothing. The result are electronic garments.

If you think the wearer has to be wired to different devices, think again. These designer clothes are wire-free, soft to touch and washable!! Like any electronic device, these high-tech clothes have to be powered. Currently, a tiny nine-volt battery serves the purpose. But the researchers hope that in the near future the clothes will generate electricity by using body heat. These clothes are 100 percent shock proof, they say.

The Electrotextiles team has also created the world’s first cloth keyboard. This keyboard can be sewn into your trousers or skirt. To use this device, you will have to sit down and tap on your lap! These ‘lap- tap’ gadgets(器具) are all set to take over laptop computers!

Another useful garment is the shirt-cum-mobile phone. This handy invention enables drivers to chat comfortably with others at the wheel! Other popular electronic wear include the denim(牛仔布) jacket with flexible earphones sewn into the hood(风帽) and the electronic ski jacket with a built-in heater. The ski jacket is also programmed to send signals to a satellite. This technology is known as global positioning system and can be used to track lost skiers and wandering kids.

Having completed the cloth keyboard, scientists have already started to work on a new project—a necktie that can be used as a computer mouse. What is the next? Do you have any idea?
