This new revolutionary Airnergy Harvesting Battery Charger literally sucks the power it requires out of thin air. It takes a WiFi signal and converts it into DC power, which can then be used to power up your devices.
The recharge time depends on the proximity to a WiFi signal. A demonstration at CES recharged a Blackberry from 30% to full capacity in just 90 minutes by harvesting the power from a WiFi signal. Check out the Video after the jump.
How It Works
The Airnergy charger operates by capturing ambient WiFi signals and converting them into usable electrical energy. This is achieved through a process known as RF (Radio Frequency) energy harvesting. The device contains a small antenna that captures the WiFi signals, and a rectifier circuit that converts the alternating current (AC) signal into direct current (DC) power. This DC power is then stored in a battery within the charger, ready to be used to recharge your devices.
The idea is to reduce the size of the technology to fit in an OEM battery, which is hoped will be available to buy for around $39. This is just amazing, considering the convenience and potential cost savings over time. Imagine never having to worry about finding an outlet or carrying around bulky power banks.
Potential Applications and Future Prospects
The potential applications for this technology are vast. Beyond just charging smartphones, it could be used for a variety of low-power devices such as wearables, IoT (Internet of Things) devices, and even medical implants. The ability to harvest energy from ambient WiFi signals means that these devices could operate indefinitely without the need for manual recharging, provided they remain within range of a WiFi signal.
Moreover, the environmental benefits are significant. Traditional batteries contribute to electronic waste and often contain harmful chemicals. By reducing the need for disposable batteries and minimizing the frequency of recharging, the Airnergy charger could help mitigate some of these environmental impacts.
Airnergy is a new battery charging system from electronics company RCA. The company has a history of innovation in the electronics field, and this new product could be a game-changer in how we think about powering our devices.
