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.

If this idea of wearing a T-shirt to detect wireless networks doesn’t sound appealing, try this standalone Wifi seeker that’s small enough to fit on a keychain.
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.
