Light-harvesting smartwatch

02.10.2017 | Tech Xplore | www.techxplore.com

LunaR is a smartwatch that is now up on Kickstarter and its key feature is a standout for those who would not like to be bothered by battery management. LunaR's team have turned to Kickstarter to get it to the next step and into people's hands.

LunaR is offering solar power in a smartwatch. Notably, the watch can harvest energy both from sunlight and artificial light. With as little as one hour of daily exposure to light, its 110-mAh lithium-polymer battery can apparently stay fully charged.

Smart watch

The watch has a transparent solar panel from Sunpartner Technologies, a company focused on transparent photovoltaic technologies. The creators gave it dual time zone functionality (the promotional video shows a man looking at his watch in office, seeing time in Amsterdam and New York). Other functions include sleep tracking and Notifications. All notifications that show on your phone are supported by LunaR. After installing the LunaR app, it will automatically index all your apps and become configurable. You can set a different LED color for each app-notification.
