Solar radiation that reaches to the
earth’s surface contains a continuous spectrum of electromagnetic radiation,
including ultraviolet (UV) light (290-400 nm), visible light (400-760 nm), and
infrared (760-4000 nm). The UV lights which are not filtered by the atmosphere
usually cover most of the UVA and some UVB lights. Normally, adequate amounts
of UV exposure can be beneficial for humans by inducing D vitamin production.
However, excessive exposure to UV lights can result with several health
problems like skin cancer, sunburn and inflammation, skin-reddening and
photo-aging. Therefore, people should be protected from long-time exposures to
UV. Especially elder people should adopt a balanced approach to sun exposure.
UV protective textiles can help to reduce side-effects of UV exposure. In this
term, the design and the coverage of the fabric and the clothing become very
important for the degree of protection. The uncovered areas of the body
maintain affected from exposure. Implementing wearable electronics to the textiles
can enhance the avoidance from excess UV exposure. By considering all these
facts, the main aim of this study was to develop a wearable warning system
which gives easy-to-understand and audible signals in case of excessive UV
exposure. The system was developed to be lightweight, compact and
user-friendly. The system mainly consisted of a reliable UV sensor, a microcontroller,
a battery, a battery charger, an OLED screen, a voltage regulator, and a
buzzer, to detect and evaluate the UV exposure and produce warning signals. The
selected UV sensor could detect the 280-390 nm light most effectively that
covered most of the UVA (tanning rays) and part of the UVB (burning rays)
spectrum. OLED screen was used as software developing and debugging aid, but also
can be used as an additive human machine interface (HMI) hardware for
prototype. The results of the developed system were also verified by using a
commercial UV measurement instrument (Lutron YK-35UV). Both the hardware and
the software of the electronic warning system were successfully developed. The
dimensions of the final system were about 10 cm in length and 2.5 cm in width.
The system components were gathered together to fit on a textile based elastic
wrist band or to be implemented on a hat or an upper garment. Possible drawings
and patterns were created to implement the system on a smart textile product.
The developed system was also tested under real life conditions. The
correlation analysis between the developed system and commercial test device
verified the performance of the developed system. In addition, vocal warnings
could be taken from the system when the pre-determined UV exposure levels were
exceeded.
