In context: Last year, Samsung introduced the Eco Remote--a television controller that promised to practise away with the need for dispensable batteries. Instead, information technology had a banking concern of solar panels that topped off an internal battery using outdoor or indoor low-cal.

This year the Eco Remote has another trick up its sleeve. Along with unveiling its newest top-of-the-line TVs, Samsung announced that its Eco Remote now includes radio frequency harvesting. A "rectenna" receives radio signals from your WiFi router and converts them to energy.

Charging via RF harvesting tin can be very slow considering the corporeality of captured energy is non that much. However, TV remotes are a perfect awarding since they are low-power devices. Additionally, the Eco Remote notwithstanding has solar and USB charging to use when needed.

Last year Samsung touted that the Eco Remote would eliminate the disposal of 99 meg batteries over the boilerplate lifespan of its TVs (seven years). Furthermore, the remote is not a standalone particular. The Korean tech giant said all 2022 Samsung televisions include an Eco Remote.

The company didn't go into bang-up detail regarding the new cool still gimmicky device, but it's not an entirely novel concept. In 2022, MIT researchers revealed that they had created a "second" flexible rectenna that they hoped to use to wearables, laptops, phones, and other devices.

Additionally, Apple and others have tossed the WiFi-charging idea around for at least five years. Apple's vision is to have RF harvesting powerful enough to charge devices that require more juice, then those efforts are withal years away.

Samsung should have more information during its CES 2022 keynote on Tuesday.
