RADIO FREQUENCY WIRELESS CHARGING
RF wireless charging is a type of uncoupled wireless charging in which an antenna embedded in an electronic device can pick up low level radio frequency waves from external sources and convert the waves’ energy to direct current (DC) voltage. The voltage the antenna harvests over the air is then used to power an electronic device or recharge its batteries. RF wire-free charging is well-suited for powering sensors and other electronic devices that run on very small batteries or use very little direct power.
WHAT IS RADIO FREQUENCY WIRELESS CHARGING ?
While certain forms of wireless charging have been in development for over a century, other newer forms of wireless charging have proven to be the next big step towards a world where wearable and electronic devices can be charged anywhere, without chargers and tangled cords. Let’s have a look at how our OTAC – Radio Frequency Wireless Charging is making waves!
The OTAC transmits the RF energy within a resonant cavity to charge the device.
1. Seamless integration Unlike induction and other forms of wireless charging, RF wireless charging is not restricted by measurements, allowing it to accommodate devices that induction cannot. Because RF wireless charging does not have the same physical limitations in size and shape, the receiver can be integrated into the
smallest of electronic devices, such as small wearables, hearing aids, and more. And that leads us to….
2. Mobility – Over the Air With RF wireless charging technology, there is no need for precise placement as there is with plugs or inductive charging pads. This means that no matter how you place your device within a certain area, it will charge – regardless of how the device is placed. Minimum Distance: 1 Feet Maximum Distance: 5 Feet (we can go above 20 feet as well) OTAC Transmitter Input Voltage: 5 Volt OTACLINK Receiver Voltage: 0.5 – 1.5 A with 5 Volt, 12 Volt, 30 Volt (We can control the voltage as per the application requirements)
3. Convenience As devices are becoming smaller and smarter, plugging everything into charge and fiddling with tiny plugs becomes a bigger hassle. Imagine an elderly person with hearing aids that need to be recharged. Having to fiddle with plugging them in every night is an incredible burden to deal with. With RF wireless charging, on can simply come in range with your tiny hearing aids (or smartwatch, or any device), Its’ charging wirelessely. 4. Never having to fiddle with multiple cords There are many benefits to RF wireless charging, but the main one is never having to deal with multiple cords! Think about all of the electronic devices you need to plug in each day, and how many different cords, chargers and electricity sockets this requires. Now imagine that you can charge all of your devices and gadgets easily, and in one convenient place! Wireless charging eliminates the need for the mess by just letting you your devices into one charging station, without having to fiddle with thousands of different cords.
In a world where everything is connected, having all of your devices and electronics be ‘smart’ is our new way of life. As these devices are becoming smarter, they are also getting smaller and more mobile. This means more small and compact devices being integrated into our everyday habits – at work, at home, in the medical world and more. Having to deal with the mess of wires and constantly plugging in cords is simply not an option. That is why wireless charging is the only natural solution to our IoT and device-infused future
Radio Frequency wireless Technology is applicable for
RF WIRELESS CHARGING TECHNOLOGY VS. INDUCTIVE CHARGING
1. Physics, my dear! Radio frequency wireless charging differs from magnetic induction first and foremost by the physical character of each technology. Inductive charging uses an electromagnetic field generated by a coil. This coil has physical limitations in size and shape in order for effective wireless charging to take place. Meaning, it can only be integrated into large, flat devices that have the empty real-estate to integrate a coil, such as a possibly a smartphone. RF, on the other hand, has a receiver based on electronic circuitry.
2. User Experience Induction wireless charging, requires transmitter and receiver for exact alignment or placement for effective charging. RF, on the other hand, is not limited by positioning for effective wireless transfer.
