Applications and Benefits in Various Industries:--
❑ Consumer Electronics: Wireless charging is now a staple for smartphones, wearables, and portable
gadgets. The removal of cables and ports also leads to more durable, waterproof devices.
❑ Electric Vehicles (EVs): Wireless charging pads are being developed for EVs, enabling drivers to charge
their cars by simply parking over a pad. This reduces wear and tear on charging connectors and offers
greater convenience.
❑ Medical Devices: Wireless power transfer enables medical implants to function without external wires,
reducing infection risks and improving patient comfort.
❑ Industrial Automation: Wireless charging technology is used in factories to power robots, drones, and
sensors, improving automation efficiency without needing constant battery changes.
❑ Space Exploration: In space missions, wireless power transfer technology could be crucial for powering
rovers, drones, or other devices without needing physical connectors, which are vulnerable in harsh
space environments.
Resonant Inductive Coupling:--
Wireless laser power transmission:-
This method uses focused laser beams
to transmit energy to a receiving
photovoltaic cell, which converts the A more advanced form of
laser light into electricity. This inductive charging,
technology can transfer power over resonant coupling uses
long distances, although safety two coils that are tuned
concerns about the use of lasers in to resonate at the same
populated areas limit its application. frequency. This technique
can achieve higher
efficiency over larger
distances.
Dynamic Wireless Charging:-- Radio Frequency (RF) Wireless Power Transfer--
This technology allows vehicles,
such as electric cars or buses, to
charge while in motion.
Charging infrastructure is
embedded in the road, and as
the vehicle drives over it, power
is transferred wirelessly to the
car’s battery using resonant
inductive or capacitive coupling.
