Description

The sun-a-wear system consists of a solar-powered, portable sensor and exclusive access to the sun-a-wear app.

The Tracker: The sun-a-wear tracker is a lightweight sensor that can be clipped onto your clothing or accessories to measure the sun's UV rays.

The App: The sun-a-wear app syncs with the tracker and suggests protective measures as well as displays the total radiation dose that has accumulated throughout the day. You can set your UV dose limit in the app and it will inform you once you have reached it. The sun-a-wear app also includes a knowledge base section with informative articles on skin health, sun protection, and more.

How it works

  1. Wear your sensor on an area of your body that is heavily exposed to the sun.
  2. Set your UV dose limit, and the app will notify you when you reach it.
  3. Receive recommendations on protective measures based on your location and time of day.
  4. Log when you apply your sunscreen in the sun-a-wear app, and it will remind you when it's time to reapply.
  5. Use sun-a-wear for yourself and your loved ones. Manage up to 4 sensors at the same time conveniently in the app.

Set it and forget it

The sun-a-wear sensor, an effortless UV radiation measurement device, remains comfortably worn on the body, allowing you to set it and forget it while it works in the sunlight.

Understanding UV index and dose

The UV index measures radiation intensity at a specific time, but the impact of UV radiation depends on total exposure. To assess accumulated UV over time, we use the UV dose — a measure indicating the overall radiation amount. This measure helps estimate the sun’s effects on the body.

What does the sensor measure?

The sun-a-wear sensor measures the UV index at irregular intervals. This depends on how much light reaches its solar cell. When the sensor is in the sun, it measures every 5 seconds. In the shade, it does this about every 20 seconds. The sun-a-wear app adds up the measurements to create a UV dose.

Solar-powered UV measurement

Worn on the body, the sun-a-wear tracker accurately measures UV radiation in the sunlight, ensuring you stay protected wherever you go. Thanks to the integrated solar cell, the sensor never needs to be charged and there is no need for batteries. Simply clip it on your clothing and you’re ready to go!

Waterproof UV sensor so you’re always protected

The sun-a-wear sensor is waterproof, allowing accurate measurement of UV radiation even in wet conditions.

What people say about us

"I see great potential in sun-a-wear technology, both for the population and for research."
Hong Phan, Chief Physician, Arzthaus Zug
"I often went without sunscreen out of convenience. That usually worked out well, but just not always. Now I feel more comfortable outdoors because when in doubt, I can check the sun-a-wear app to see what my UV exposure is and put on cream when necessary."
Tim, sun-a-wear user, Zurich
"With my dark skin, I don't use sunscreen because I suffer from vitamin D deficiency. Still, it's important for me to know at what point the UV rays are more harmful than their benefits. That's why I use sun-a-wear daily and can balance it."
Jenny, sun-a-wear user, Bassersdorf
Swiss quality
Every sensor was developed and manufactured in Switzerland.
