The Genesis of The Gem
Stacy Salvi, leveraging her extensive experience at Fitbit, envisioned a device that could seamlessly integrate health monitoring with daily life. The Gem was born from this vision—a smart necklace that doesn’t just sit pretty but actively contributes to your well-being. This device takes the form of a stylish pendant, embedded with sensors capable of measuring UVA and UVB rays.
Understanding UV Radiation
Ultraviolet (UV) radiation is a form of electromagnetic radiation emitted by the sun. It comprises three types: UVA, UVB, and UVC. While UVC is mostly absorbed by the Earth's atmosphere, UVA and UVB reach us and can have significant effects on our skin. UVA rays penetrate deep into the skin, causing aging and long-term damage, while UVB rays are responsible for sunburn and can directly damage DNA, leading to skin cancer.
The Role of The Gem
The Gem is equipped with cutting-edge sensors that continuously monitor UV exposure. Whether you're out for a walk or sitting by a sunny window, The Gem captures real-time data on UV radiation, offering insights into your exposure levels throughout the day. This information is crucial for anyone looking to manage their skin health proactively.

How The Gem Works
Sensor Technology
The heart of The Gem lies in its sensor technology. The necklace features miniaturized sensors that detect the intensity of UVA and UVB rays. These sensors are designed to provide accurate readings regardless of the user's location or activity, offering a comprehensive view of UV exposure.
Data Collection and Analysis
Once The Gem collects UV data, it communicates with an associated smartphone app via Bluetooth. This app is where the magic happens. It processes the sensor data to create a detailed UV exposure profile for the user. This profile includes historical data, current UV index readings, and forecasts that help users plan their day with sun safety in mind.
Personalized Skin Profiles
The app goes beyond just data display; it provides personalized skin profiles based on individual exposure trends. Users receive tailored advice on sun protection, such as optimal times for sunscreen application and safe exposure windows. This feature empowers users with actionable insights, making sun safety a proactive part of their routine.
