UV Exposure Assessed With Wearable Sensor and Sun Protection

The goal is to prevent ultraviolet light (UV) overexposure by providing consumers with relevant, easy-to-access, specifically actionable information. This research proposal will develop a UV protection system consisting of an automated real-time counseling framework and a personal dosimeter that overcomes barriers to consumer adoption. These new, wearable sensors take the form of small (< 1 cm), thin (<0.1 mm), lightweight (<0.1 g), battery-free "stickers" that are fundamentally differentiated from other wearable electronics in their modes of use, cost structures and accuracy.

About this study

The proposed work is to refine and validate a UV protection system based on a dosimeter "sticker." The key innovations of the system are automated personalized intervention messaging triggered by the exposure levels measured by a novel charge accumulation device applied to ultraminiaturized circuit forms. The research will validate the system's accuracy and acceptability to users, refine the device, and prove its robustness and efficacy in real world use cases. Focus groups and structured interviews will develop sun protection strategies to be communicated by text messages to participants. Successful completion of the research will yield a system to prevent excessive UV exposure and sunburn, thus reducing the incidence of skin cancer by equipping large numbers of general-population consumers and at-risk people to practice digitally-informed healthy sun behavior.

  • history of sun sensitive skin, skin type 1-3
  • have a smartphone and willing to use the UV guard application on the smartphone
  • reliable wireless internet connection to complete daily surveys
  • willing to wear the sensor for 28 days and transmit data and complete daily surveys
  • willing to receive SMS text messages on their personal phone and potentially sync sensor to personal phone using Bluetooth
  • If weather permits, person will spend at least one hour outdoors each day, with at least 30 minutes of that hour being consecutive between the hours of 8 AM and 5 PM

Treatment and study plan

Goal attainment

Behavioral

After reviewing daily UV exposure in the prior 10 days, participants will be randomized to structured (select strategies from a list of 7 items) or unstructured (submit a free text description of a strategy) goal attainment.

Primary outcomes

  1. Acceptability of Wearing UV Sensor and Receiving Text Messages

    Time frame: cohort study 1 (arms 1 and 2) at end of 21 days, cohort study 2 (only one arm) at end of 28 days

    Online system usability 6 item scale (Likert 7 items range from strongly disagree to strongly agree Minimum value 6, maximum value 42, higher score better outcome

Secondary outcomes

  1. Sun Exposure in Participants With Structured vs Unstructured Goal Setting

    Time frame: 21 days

    Change in daily UV exposure recorded by UV sensor (J/m^2/day) between period prior to and after goal setting among melanoma survivors

Other outcomes

  1. Participant Reported Sunburns Prior to Intervention and During the Intervention

    Time frame: 56 days

    Young adult participants with sun sensitive skin reported sunburns in the 28 days prior to the intervention and during the 28 days of the intervention.

  2. Knowledge of Sun Protection

    Time frame: 2 months

    Knowledge of sun protection using the scale after completing focus group after completing an arm of the study. The same scale was administered at baseline for each arm.

    9 item scale (Minimum= 9, Maximum=18) Total range is 9-18. Higher value is better knowledge and a better outcome.
