This MSc-thesis made by Silvain Toromanoff is a spin-off based on OJAS. I was Silvains advisor, and behind the original concept.
The idea focused on combining lighting, wireless power and wearables, to the improve the safety of preschoolers. Apart from the summer, Finland tends to be quite dark place, and even though the children usually wear safety vests with reflective strips, they are not easy to see.
In order to increase the visibility of the children, a concept with a LED-lit jacket powered wirelessly through a rope was created. The children are typically lead though the streests using a rope, which the children can grasp. In addition to help them with the walking and staying in group, it could also supply electricity to their jackets. The idea was to make grabbing the rope fun, and provide an additional safety by enhancing visibility.
In the thesis, one early proof-of-concept prototype was created and demonstrated.
