A new bag can identify the contents and remind the owner if something is missing. Ladybag bags aimed at the trendy girl, sometimes leaving home forget cell phone, key door or wallet.

" Our team consists of six girls, and we come up with the idea that all women in the world need it, " said team member Ginny Mesina, Fraser in Canada, said.

To design this bag, the students used the technology available. At the bottom of the bag they put a radio frequency meter, charged with a 9 volt battery. The meter is connected to a panel like a screen in front of the bag, with three types of light-emitting diodes.

Each diy is a symbol representing something that the owner of the bag does not want to forget when leaving home. In the prototype, these items consist of a key ring, a purse and a telephone. They then attached an RFID sensor to each of these objects.

If something is not in Ladybag, the corresponding icon will glow. When the key, telephone or purse is returned to the old place, the beacon will turn off.

" I always forget my phone, but I always carry my bag." This is a great initiative, "says industrial designer Rosanna Kilfedder, of Heriot-Watt University in Edinburgh, Scotland. Kilfedder designed the Suntrap handbag, a bag that is loaded with solar energy by absorbing daylight and glowing at night so that the owner can easily see the object.

The Ladybag research team is aiming to create 20 bags of memory.
