SmartFish demonstrator presents a printed temperature sensor on a thin plastic substrate embedded to a hybrid wireless communication real-time cloud-based temperature and location monitoring system for monitoring fish transport chain. Temperature conditions are very important to easily-perished products and therefore temperature measurement is crucial in cold chain. Effective tracking of temperature conditions is the most important point to be focused with technical and organisational solutions.

Flexible OLEDs have the potential to be integrated into formed parts or seamlessly bonded onto curved surfaces, and the commercialisation of this technology will open up a host of exciting design opportunities to create new value adding lighting products in many different application areas, such as architecture, automotive, aerospace fashion and consumer electronics. PI-SCALE is a European collaboration to create an open access pilot line service offering world class capability in customised flexible organic light-emitting diodes (LYTEUS OLEDs) in order to accelerate the commercial adoption of this technology.

A design accessory for monitoring the indoor air quality

VTT has developed a design accessory for monitoring the indoor air quality in facilities such as offices and classrooms. It detects carbon dioxide, temperature and humidity, and uses light signals to guide people to healthy space. The monitor, which is based on IoT technology, uses comfort light signals to guide people if, for example, carbon dioxide levels in a room become too high. LEDs of different colours indicate when the level of gas measured by the sensor exceeds a certain threshold.
