Update September 2020:
Unfortunately no new UV-protecting mask has been designed in the course of this project. However it has spun off a development project for a low-cost UV meter. This meter called LUVI has been successfully tested by users and a series of devices has been produced and is now in use by children afflicted by XP. See the LUVI project.
UV-mask is a UV-mask meant for people with a highly sensitive skin.
It features 100% protection from UV and has an integrated fan.
The full design (electronics, mechanics and software) is available under
free licenses and the design is exclusively made with free tools.
The project started with ThePort
hackathon 2015 to help to
children suffering from Xeroderma pigmentosum (XP), a genetic disorder
that causes extreme sensitivity to ultraviolet light. Special equipment
has been developed to protect them from UV exposure and is in use since
2014 but it still has some issues with acoustics, temperature control
and durability. The association THE Port started this project to help
the children afflicted by the disorder and their families.
The aim of this project is to create a mask with several improvements:
a more effective ventilation system to reduce the amount of steam
that forms on the screen of the mask, especially in winter, and to
improve wearer comfort in warm temperatures,
a more ergonomic visor design with better acoustic properties to
avoid reflection of the wearer's voice,
different sizes of mask, i.e. one size for children and another for
adults and teenagers,
a technical material for the hood,
a battery system indicating the run-time of the ventilation system,
improved communications possibilities.
Work on the mask in October 2015 (click picture to enlarge)
