Raymio – Sun Protection Wearable: We have created a wearable UV sensor to help you stay safe in the sun!

iCrowdNewswire - Sep 30, 2015

Raymio – Sun Protection Wearable


Four reasons to support Raymio and get your own wearable UV sensor:

  • Protect your skin and eyes: UV radiation is a risk factor

  • Worry less: get to know exactly when you should use sun protection

  • Help protect other: share and care with friends and family through our app

  • Donate your exposure data to cancer research: we need more knowledge!

You probably know that ultraviolet (UV) radiation causes premature aging of your skin. But did you know that sunburns are a serious health risk? When your skin peels off after a sunburn, it’s a part of your largest organ shedding off to avoid that DNA damage within it results in skin ailments like melanoma. As you accumulate exposure, risks increases – even if you don’t get sunburned. You want to keep your UV levels with a healthy range. If you live an active lifestyle, monitoring this represents a serious challenge. That’s why you need Raymio!

We know that getting sun safety right isn’t easy. That’s why we’ve created the world’s most advanced UV wearable.

Raymio register your UV A+B exposure and offer personalized protection according to your skin type. It helps you prevent excessive exposure which can cause sunburn and other UV related discomforts by advising you when to put on sun lotion, seek shade and which types of clothes you should wear.


For every dollar you support us with, the Danish Market Development Fund gives us three!

We have to report to the fund until the final product is developed and delivered to you. This is your guarantee that we will deliver if we reach our goal!

Raymio has been thoroughly vetted: our participation in this programme requires rigorous screening of our company and product development.  

We’re also supported by Innovation Fund Denmark and the Danish Foundation For Entrepreneurship.


The Raymio App will send you a notification on days when the UV index is high and remind you to wear the device.

Raymio store data and send continuous updates about your sun exposure to the mobile app throughout the day. To ensure accuracy, the unit utilizes internal directional sensors to estimate the sensors’ position in relation to the sun. We call this feature 360° Sun Safety. To create a fail-safe, we have partnered with theDanish Meteorological Institute, who provides us with UV index satellite data. Even if your Raymio sensor doesn’t face the sun, it will not presume that you are not exposed to sunlight: our algorithms will compensate for temporary drops in input or a downturned position.


Electronic engineer with 25+ years of experience in developing and manufacturing hardware, Kjeld is the man who guarantees the development of a high quality product. We are creating the most advanced UV wearable on the market.


Select the wristband color you like the most. The finished wristband will be moulded in thermoplastic elastomers (TPE). The material is non-allergic and very comfortable against the skin. Our current protoype is sand casted, so it looks a lot rougher than a final product. We offer our early bird backers a black wristband. Backers who pick another reward can choose between between three more colors: white, yellow and blue. 



Do you know the feeling of sunburn? Have you spent an afternoon on the beach only to end up with skin peeling? Or did a high UV index ever catch you off-guard during travel, on your outdoor exercise routine or your daily commute? Is your skin extra UV sensitive? How about your family or friends? 

Raymio is a great tool for people who wish to take care of their skin while enjoying an active lifestyle. It is a situational awareness aid: We want to help you with actionable advice. It’s also a biometrics tool where you can track your exposure history. 

Raymio provides information that help you become more familiar with your own skin and the effects the sun. The wristband keeps track of your UV exposure and keeps you updated. The app lets you keep track of groups, your friends and your family. Raymio app also contains forecasts, statistics and advice on sun safety. It includes social features, where you can connect with your friends and family in order to help each other keep healthy UV exposure levels. These features are of course optional: you only share the data you want to. 

You can also donate your anonymized data to science!


We want to provide you with an elegant aid for everyday sun safety with minimal hassle. You don’t need to check your phone to use Raymio: the wearable works autonomously and signals you with a LED when you need to take action. You can take Raymio swimming and stay informed of your exposure.

POWER ON. An LED indicator around the UV sensor shows you that Raymio is activated.


By taking advantage of directional sensors within the unit, Raymio can provide a much more accurate estimate of your UV exposure level. We’ve developed an algorithm which enables Raymio to use UV index forecasts and measurements of your personal UV exposure throughout the day to tailor advice to you. A gyrometer and an accelerometer provides additional data points: Raymio will at any time know which way the wristband is turning in relation to the sun. This enables the unit to calculate a more realistic estimate of your UV exposure – not just how much UV exposure the sensor in the wristband has picked up. We call this feature 360° Sun Safety. 

Raymio caters to all skin pigmentation variants. We use the Fitzpatrick Scale – the official standard numerical classification schema for human skin color – to classify your skin type and predict how it reacts to UV radiation. Learn from your past through statistics.


A wristband can be used by an individual or by a group of people with different skin types. A family can use a wristband each, each keeping track of their own exposure and the exposure of family members by merely adding them as friends. The family could also add themselves as three separate users, using UV data from a single wristband. In the application main screen the family members would have separate profiles. The sensor unit can be removed from the wristband and put anywhere. This could be useful for group settings. It also allows you to change wristband.

The applications is stacked with features! We strive to give you the greatest possible utility of your data.


If you spent too much time in the sun yesterday. Raymio will be aware  and make sure to tell you to take care. Or maybe your hair has started thinning? Let Raymio know, and it’ll be able to inform you that you might want to put on that hat 30 minutes before you’d otherwise would. Or maybe you’re out running when the sun is at its highest. Raymio will remind you to use sunscreen and adequate clothing.


AT YOUR FINGERTIPS. View your actionable profile data with a UV index 


Seeing your exposure statistics can be a learning experience. Maybe you are exposed to UV radiation during the afternoon without realizing it. Or maybe you generally sit too long outside on summer days. With Raymio, you’ll know and be empowered to take action accordingly. You can also compare stats with friends and family, learning from each other’s experiences.

Get better at sun safety with your family and friends. Share your profile, send notifications to remind others to apply sunscreen or seek shade. Your friends can notify you too, if you wish. Helping each other is a great behavior change strategy.

Would you like to learn more about sun safety? What does ‘factors’ in sun lotion mean? How does UV affects toddlers and children? Or maybe you’re interested in learning more about your own skin type and how it’s affected by the sun. Delve into the sun library and get to know more.


All backers will receive a code to become part of an exclusive user focus group. Please download our application prototype after the campaign conclusion: We want to understand your needs and hear your ideas! You will have a direct access to developers, allowing you to have your say on the development of the app. You can use the application before you receive your Raymio unit: the application has UV forecast and tailored advisory profile implemented, but cannot of course measure your UV exposure without the sensor unit. 

Crowdfunded hardware projects often struggle to meet delivery dates and meet problems in scalability. We know how frustrating this is for backers: that is why we have set up our entire supply chain in advance. We have +25 years production and shipping experience available in our team. So we are well prepared to handle our backers’ rewards.

Risks and challenges

Producing a hardware product is not easy and unforeseen risks can occur. Plenty of crowdfunded electronic products have certainly gone off-track in the manufacturing phase. We’re doing our best to anticipate risks. Raymio will be a sophisticated piece of technology and sometimes even the big players mess up in creating and scaling hardware products. But we have two huge advantages. 

Our technical team is led by senior professionals with more than 25 years experience in developing and manufacturing state of the art electronics. 

We have entered a manufacturing agreement prior to the Kickstarter campaign. This means that we won’t be spending precious time finding a manufacturing partner after a successful crowdfunding round. Our engineers have been working with the manufacturer multiple times over the past decade and can guarantee their timeliness and production quality. 

Our match-funding agreement with The Danish Market Development Fund means that crowdfunding funds will be amended with a substantial amount. This ensures that we will not run out of funds before we have delivered rewards to our backers.
