Sun4Health addresses the most important open issues related to solar light impacts on human health. Other devices and mobile apps available do not match the actual needs of market and end-users. Indeed, they address only UV radiation monitoring with limited performances, being focused just on sunburn avoidance with many drawbacks: users should direct the sensor toward the sun continually for a reliable sun exposure control or other passive systems work effectively for a single body part only, being unable to notify users with an alert for avoiding sunburns. The new Sun4Health solution allows the UV radiation dose control in all body areas simultaneously, supporting sunburn avoidance in the most exposed ones also by alert notifications. Another innovation is that both the smartphone and the connected wearable sensor could be also unexposed to sunlight as the real-time satellite data are fully exploited for radiation monitoring. Besides, Sun4Health introduces a new way to manage sun exposure. It faces also other effects of solar radiation by monitoring several selective spectral regions, such as the sun induced Vitamin D and the UVA & NIR induced skin photo-ageing, allowing the best personalised benefits / risks balancing for different end-users (e.g. children, outdoor workers).
The key user needs addressed by the project both for end-users (people that will use the app for personal healthcare services) and for customers (companies involved in the product with a B2B scheme or paying for a related service such as Business Intelligence) are:
The Sun4Health solutions address diversified markets of significant size (multi-billions). The key customers belong essentially to the Health & Wellness related sector in all the different areas involving outdoor activities.
In order of priority for Sun4Health products they are:
The Sun4Health project is supported by Public Health England (UK) and ACM - Association Against Melanoma (Italy) who will be providing in-kind contribution in term of support for specifications and testing.
Sun4Health combines the Earth Observation satellites measurements and the exploitation of specific wearable sensors to allow accurate, reliable, personalised and real-time information about the solar radiation experienced by the end-user in any part of his body, discriminating the different benefits and health risks.
Devices and apps currently available do not answer to the needs of the market, as they address only the monitoring of UV radiation with limited performances and they are focused on sunburn avoidance with many drawbacks: users should direct the sensor toward the sun continually for a reliable sun exposure control or other passive systems work effectively for a single body part only, being unable to notify users with an alert for avoiding sunburns. The new Sun4Health solution will allow the UV dose control in all the body areas simultaneously, supporting sunburn avoidance in the most exposed ones also by alert notifications. The Sun4Health system concept and method is patent pending.
Sun4Health exploits two space assets: Satellite Earth Observation and Satellite Navigation.
Earth Observation satellites are used to retrieve the solar irradiance at ground (especially geostationary satellites) in real–time. The solar irradiance is measured exploiting atmospheric parameters obtained by EO-based Copernicus web services as well as by dedicated Flyby’s internal processing algorithms and procedures (e.g. solar radiation filtering properties of the atmosphere in different spectral regions). The solar irradiance derived by satellite data processing is in the following spectral bands: UVB, UVA, VIS and NIR. The spatial resolution varies from 3 km2 to 15 km2 (depending on latitude).
The time update period for fast atmospheric evolution phenomena (like clouds) is at least 15 minutes, while for slow ones (like ozone) is daily. A dedicated nowcasting algorithm is exploited to reach an overall resolution of 1 minute for the service.
The Sun4Health project exploits the following satellites:
Satellite navigation data (GPS, Galileo and AGPS from mobile devices) are exploited to obtain the position of the end-users and to track its movements.
