A fencer is not allowed to leave the field with the foot. An umpire must also pay attention to the hands and the foil. It is difficult to also pay attention to the feet if it has been outside the lines.
Put sensors in the shoes that detect. If a foot is outside the lines then a signal should be given.
Place magnetic sensors in a sports shoe (front, back and side of the shoe). Link sensors to a battery pack. Create a test field with metal lines. A buzzer gives an acoustic signal when the shoe lands on the line. All required components were self-assembled. A working system was demonstrated at the end of the day.
Team: Team solarjacket phonecharger
School: Kaiser-Karls-Gymnasium, Aachen, Duitsland
On a cycling or hiking trip, a cell phone is used e.g. to listen to music. This causes the phone to consume energy. If the phone runs out of energy it cannot be charged.
A jacket with solar cells and a pocket in which the phone fits and can be recharged.
Flexible solar cells are placed on a sports jacket. On one sleeve a pocket was made for a phone. In the sports jacket, a connection was made from the solar cells to the pocket for the phone. In the phone pocket a connector is placed for the phone.

1. In handball, a foot may not step on the line. However, the player is allowed to jump over the line. Many players walk along the lines in front of the goal and it is difficult to see if someone is on the line or not.
2. If the ball has just crossed the goal line, it counts as a goal. It is difficult to tell if the ball has been over the line or not.
1. If a foot gets on the line a sound signal should go off.
2. If the ball crosses the goal line a light should come on.
1. On a playing field apply two copper tracks. To these tracks make a battery with a buzzer. Make a shoe with a metal strip on the outside of the shoe. When the shoe hits the two copper strips it makes contact between the two strips and the buzzer goes off.
2. On the goal line there is an optical sensor. As soon as the ball crosses the line, a light comes on.
Team: Team Illumicoat Bike Traffic
School: Bravo College, Budel, Limburg, Netherlands
On a bicycle you have a lamp at the front and at the back. In places where there are no and few street lights, you can't see if someone puts their hand out to enter a street. This is not safe.
A jacket with lights on the arms that turn on when you put your hand out.
Put flexible LED lights on both sleeves of a coat up to the hands. Inside the jacket conceal a battery pack. On the inside of the jacket make a pull connection to a switch. When the hand is horizontal, the switch should make a connection so that the LED light lights up. Where the wires contact the LED lights is waterproofed with flexible and waterproof material.
Team: Team Swimming Guidance for the sight-impaired
School: Vrije basisschool De driesprong, Bilzen, Flanders, Belgium
How can blind and visually impaired people swim lanes independently?
A swim cap with hearing aids that beeps left or right if you don't go straight. When you get to the end both sides give sound.
The goal is to demonstrate how it works, not to make a working model for in the pool. On a swim cap, buzzers are placed at the ears. On a tableau, switches are one for each buzzer. On this tableau a battery is placed to power the buzzer. A cable connects the tableau to the bathing cap. The operation is tested with a person wearing a blindfold. The person with the tableau can operate the left and right buzzer separately. The operation has been proven by having the blindfolded person walk through different premises and along objects.
