A real time cost effective accurate UV measurement and sun protection system to prevent and reduce the incidence of sunburn in high risk consumers

PROJECT SUMMARY ABSTRACT The US Surgeon General reports that skin cancer is the most common type of cancer in the US The number of Americans who have had skin cancer at some point over the last three decades is estimated to exceed all other cancers combined There are more than new cases of melanoma each year resulting in more than deaths Reports indicate that nearly of skin cancers are caused by UV exposure and despite the risks many Americans continue to subject themselves to harmful levels of UV partly because it is burdensome to accurately assess oneandapos s UV dose Furthermore the experience of sunburn or even melanoma often do not provide sufficient motivation to change sun behavior Wearable UV monitors offer potential remedy but existing devices are expensive obtrusive and often incompatible with water recreation Their intrinsic operational mode has inaccuracy derived from intermittent measurements and interpolative algorithms to infer dose These shortcomings cause non adoption improper use or discontinuation limiting their ability to prevent overexposure sunburn and skin cancer A critical unmet need is for a low cost unobtrusive sun protection system that combines accurate dosimetry with user responsive software interfaces capable of influencing healthy behavior The proposed work addresses the need with a breakthrough sensor technology and an innovative user interface that enables informed sun protection behavior The sensors are pea sized battery free stickers with fundamentally differentiated modes of use cost structures and accuracy Uninterrupted charge accumulation imparts continuous UV A and UV B measurement capability with greater accuracy than any alternative The result is a personal dosimeter with vanishingly small obtrusiveness and correspondingly small cost allowing giveaway distribution strategies Real time messages triggered by user specific exposure will promote healthy sun behavior in the general population and at risk segments including those with medicine induced photo sensitivities or diseases that increase sensitivity to the sun Activities in Phase I will establish the accuracy of the sensors through systematic comparisons to non wearable laboratory instrumentation and produce a mobile app with bi directional communications based on UV tolerances specific to the userandapos s skin type Focus groups will assess the usability of the system and its likelihood to influence sun protection behavior Phase activities will optimize designs for cost and reliability in real world conditions with targets of andlt $ per device and robust operation during after watersports and heavy sweating Successful completion of these tasks will enable assessment of the technology in prospective cohort studies in high risk populations of melanoma survivors aged Extended day behavior studies of individuals will determine compliance target andgt and user satisfaction target andgt to confirm broad acceptability and efficacy in influencing healthy sun behavior PROJECT NARRATIVE The goal of this project is to develop a broadly adoptable accurate sun protection system that pairs innovative body mountable sensors with a smartphone application to equip users for effective sunburn prevention based on real time personalized actionable assessments of UV exposure and user responsive software interfaces capable of influencing healthy sun behavior The sensor at the core of this system will exploit a novel continuous charge accumulation measurement approach that enables battery free operation ultralow cost construction and miniaturized size capable of comfortable imperceptible integration on any part of the body including the fingernail or the clothing and rapidly scalable distribution strategies This solution will help reduce skin cancer incidence by increasing awareness of the risks in a broad segment of the population and providing specific targeted user recommendations and education for prevention
