WEARABLE SELF-POWERED WIRELESS UNITS FOR ULTRAVIOLET RADIATION DOSIMETRY

The protection of workers and individuals exposed to physical phenomena impacting on health, represents a challenge for the next future. An ideal solution is represented by the use of non-invasive, low cost, wearable and washable devices, able to detect continuously personal exposure and activate alarms in case of hazardous events. The devices are miniaturized in dimensions and weight and provided with a radio interface, forming a set of wearable mobile nodes in a wireless network. Furthermore, the node embeds energy harvesting techniques for self-powering. The wireless device can connect to a standard wireless networks (Bluetooth, ZigBee), as well as to Ad-Hoc ones, by means a dedicated skin antennas. As an example, the methodology is applied to assess UltraViolet (UV) exposure to prevent diseases due to under- or over- exposition to UV rays. The preliminary studies confirm the feasibility of the project.
