For several years now, we have seen the enormous growth in the wearable device sector, a sector in which smartwatches are among the main protagonists. Often, many of the more interesting models emerge thanks to crowdfunding platforms like Kickstarter. Today we will talk about LunaR, which according to the makers, is the world’s first smartwatch that runs on solar energy.
There are smartwatches that can hardly come alive at the end of the day, to withstand the months and even years compared to traditional watches. For this reason, and to increase the comfort of the owners of this type of watches, the LunaR company brings the ultimate solution: a smartwatch that is charged by solar energy.
If we focus on some of the features that LunaR creators wager on, the smartwatch we're talking about combines the design of a traditional watch with the potential of today's smartwatches. Like all other smartwatches on the market, LunaR is able to keep track of your activity, show notifications on your smartphone and analyze the quality of your sleep. You simply need to install the LunaR app on your iOS or Android smartphone. The app works with iOS 10 (and higher) and Android 4.3 (and higher).
The smartwatch is limited by not having a display (as it would consume too much power and would be unsustainable to be charged by solar energy only). Instead, the smartwatch gives you information with the help of LEDs embedded around the ring of the watch. LEDs are not only used to indicate, for example, how many miles you have traveled but also serve as a notification method (depending on which LED is lit, you will know what kind of notification you have received).
In addition, the LunaR smartwatch is water resistant up to 5ATM, so you wouldn’t have to worry about any damages while swimming in the pool or the sea.
But without a doubt, the potential of LunaR lies in the fact that the smartwatch works thanks to solar energy. To do this, the team at LunaR incorporated a solar panel capable of maintaining the load of the watch with both natural and artificial light, which is a whole point in favor. The innovative transparent solar panel was developed by Sunpartner Technologies, a leading solar technology company from France. It is able to charge the Li-polymer 110mAh battery from any source of light with maximum capacity. In addition, the LunaR app enables you to monitor at all times the current light-harvesting levels.
The company promises that the battery needs only one hour (>10k LUX) of charging a day, and in addition, the exposure to the light does not have to be discontinued. That is, the battery can be charged in sequences, without having to expose the smartwatch to light continuously for one hour a day. Thus, it will be enough to carry the watch while you go to work or while you’re out to lunch.
In addition, you can charge the smartwatch not only by sunlight, but it works with artificial light too. A USB charger is included in the package, just for emergencies.
As for the design, it is as we see it: the lack of graphic elements is precisely what gives the LunaR smartwatch a very attractive appearance. The watch’s ring measures 41 millimeters and is made of stainless steel.
Undoubtedly, the potential of a smartwatch capable of running on solar energy has captured the attention of Kickstarter users. With less than a month left to close the crowdfunding campaign, LunaR has already raised over 89,000 of the $50,000 needed. The smartwatch will sell for a price of $138 and will be available from December.
The LunaR smartwatch with sapphire-coated glass is available on Kickstarter for a price of $138, which you would receive in December this year. Another version with full sapphire crystal is also offered at $169 but it won’t ship until March 2018.
