If you are not carrying a wi-fi enabled mobile phone and hate to turn on the laptop computer just to check if there’s a wireless network around, try this Wi-Fi enabled Tee Shirt.

The wi-fi shirt, made of pure cotton, can detect wireless networks in your vicinity and displays the signal strength as animated glowing bars as shown in the picture.

This Wi-Fi detector, that works with 802.11b or 802.11g networks, requires three AAA batteries and you can detach this unit from the T-Shirt to avoid any damage at the time of washing.

The device is equipped with a wireless network signal strength indicator that allows you to determine the availability as well as the quality of the wireless network - even before you boot-up your laptop.
