This over the air phone-charging tech is straight out of
sci-fi movies
Tech giant Samsung
has patented a new technology for OTA (over the air) wireless charging. The
patent is unlike the existing wireless charging tech, which doesn’t even require
the phone to be kept on a charging pad.
Currently, the wireless chargers used with Apple and
Samsung smartphones charge the phones without needing to connect wires
physically but they still restrict free movement of the phone. The patent was
published by the World Intellectual Property Organisation and was filed in
2016. It’s still unclear if Samsung is actually developing the wireless charger
or they just patented the idea before anyone else.
Tech it resembles
In December 2017, the US Federal Communications
Commission (FCC) approved a similar truly wireless charger called WattUp,
developed by the San Jose-based startup Energous.
WattUpp uses radio frequencies to charge mobile
devices at a distance of up to three feet. There is a transmitter that converts
electricity to radio frequencies, which are then beamed to devices with a
compatible receiver.
How will this work?
In Samsung’s case, the patent images show similar
charging units along with reflectors placed across room. They would transmit
energy in form of waves, where reflectors will let them travel to the device
without any blockage.
There are no details about the development and
release of the technology. Emitting energy in a closed area wirelessly is a
tricky task but making it safe to use in a household is a bigger concern.
