Dampness sensor
1. The dampness sensor consists of a paper base with an electronic circuit which is printed on the paper with conductive ink in multiple layers. Any moist or dampness added to the circuit will serve as a catalyst which together with the circuit will produce an electric current.
2. The current is lead to a reusable signal unit. The unit can be equipped with LEDs, a buzzer or a chip with a radio transmitter (RFID). The RFID can communicate a vast number of different data, such as the id of the sensor or it's log. The system is easily adapted to both current and future communication solutions
Other areas where it can be used:
3. Against fire: A small pod filled with a liquid is placed on top of the sensor. When fire breaks out, the temperature will make the pod burst and the liquid will alert the sensor and a signal can reach the fire alarm inside the building.
4. Frozen goods: The sensor is frozen when moist and placed inside a container with frozen goods. If the temperature inside the container reaches above 0°C, the ice will melt and a signal will warn that the goods are about to thaw.

Material: Interview over the phone with a contact person at the company.
Tools: Illustrator to define the outlines. After that the work was moved to Photoshop for colouring, structures and shadows.
