Last year, Samsung introduced the Eco Remote — a TV remote that promised to eliminate the need for single-use batteries. Instead, it had an array of solar panels that filled the internal battery with either external or internal light.
This year, the Eco Remote has another trick up its sleeve. At the same time as it revealed its latest TV, Samsung announced that the Eco remote control now includes radio frequency capture. A "rectenna" device receives radio signals from your WiFi router and converts them into power. p>
Charging via RF reception may be very slow because the amount of power received is not very large. However, TV remote controls are a great app because they are low power devices. Plus, the Eco Remote still comes with solar and USB charging for use when needed. p>
Last year, Samsung announced that the Eco remote control would eliminate 99 million batteries during the average lifespan of its TVs (seven years). In addition, the remote control is not an independent element. The Korean tech giant said that all of its 2022 Samsung TVs have environmentally friendly remote controls. p>
The company has not gone into many details about the interesting new device, but this is not a completely new concept. In 2019, MIT researchers unveiled a "2D" flexible rectifier they hope to apply to wearables, laptops, phones and other devices. p>
In addition, Apple and other WiFi carriers have been excluded. Ideas for at least five years. Apple's vision is for radio-frequency capture to be powerful enough to charge devices that need more water, so those efforts are still years away. p>
