A group of students from a middle school in Shenzhen has invented a smart backpack that can warn you when you forget your things. The backpack has a small sensor inside. When you leave something important — like your keys, wallet, or books — behind, the sensor sends a signal to your phone. Your phone then vibrates and shows a message: "You forgot your keys!"

The idea came from a common problem. Every day, the students saw classmates rushing back to the classroom because they had forgotten their homework or lunch boxes. "We thought a backpack should do more than just carry things," said one team member. "It should help you remember."

The team spent six months designing the backpack. They tried over 20 different sensors before finding the right one. The biggest challenge was making the battery last long enough. After many tests, they finally created a battery that can work for a whole month on one charge.

Their invention won first prize in a national science fair. Now, a company in Shenzhen is working with the students to make the backpack available in shops. "We hope our idea can help students everywhere," the team said.

3. What was the biggest challenge the team faced?
