The electronics used were the lilypad, heatpads, transistor, pressure sensor, battery and LED lights.

In the event of an emergency, the pressure sensor is activated, causing the heatpads to generate. The heat generated will cause the entire neckpiece to be heated up, thus preventing people from getting hypothermia while in cold water.

The LED lights are also generated to be red in colour, in a way that it sends SOS signal when in danger.

My kind friends helping me out with the placement of the LED lights around the interior of the neckpiece <3

A little pouch with velcro at the back of it was made, to contain the battery.

LED lights were installed at the seam of the neck piece, such that the light can bee seen through the fabric, yet be stable.

The end result of the electronics
