Intelligent sensors for ultra violet detection

This paper presents an innovative, simple and creative approach to detect harmful level of ultra violet light on human skin. The harmful level of ultra violet rays is first defined with the existing harmful level standards identified by governmental and medical authorities, and then different existing detection mechanisms or apparatus are evaluated. Finally proposed affordable solutions and Matlab/Femlab simulations for personal UV sensor are presented using MEMS/MOEMS or chemical technology. This intelligent dynamic sensor detects the harmful level of UV and dynamically informs the user about the need of some kind of protection against the high UV radiation levels. The criteria for the choice of solutions are based on low cost, practical and reconfigurable wear, response time, non disposable, autonomous operation (visual-no battery) and handicap dependant operation (acoustic-with battery). Packaging of these devices would need to respect the above criteria.
