Russian Startup Reasonance Presents
Dual-Mode Wireless Power System at CES

" Our solution combines both inductance and capacitance solutions in a single package. Whilst our competitors utilize wiredconnected oscillating circuits which consist of two elements,
we managed to make the coil function as a capacitor. We have
created a single-element oscillating system which performs both
functions at the same time; moreover, our number of oscillating
circuits is unlimited. "
" While we also use the well-known resonance
phenomena in transmitting and receiving
systems, the fundamental difference is that our
technology contains both inductance and capacitance components in one single structural
element, " adds Andrey Tarasov, CTO. " Classic
magnetic resonance uses only a magnetic
field, while Reasonance uses both magnetic
and electric fields. This ensures remarkable
characteristics of wireless energy transfer
and reduces costs by 80-90 % compared with
competing technologies. "

No passports or airline tickets were required at this year's CES
for a Russian startup to introduce its wireless power transfer
system that steps up the capability for product designers to go
cordless. CES, the giant electronics fest traditionally held in Las
Vegas and known as the Consumer Electronics Show, was held
digitally this year due to the pandemic yet exhibitors such as
Reasonance, a team of Russian scientists and engineers, were
able to virtually demonstrate their technology applied to a largeformat TV powered without wires. It can be suitable for many
other applications, they say.
" Our technology is significantly more
advanced: a magnetic field is generated
by both conductivity and displacement
currents and, therefore, ensures major
advantages in wireless power transfer,
says Anton Vishnevsky, founder and CEO,
who is also shown at top. " There are various ongoing projects of wireless power

resonance or induction, " he explains.
" Whilst these are only relatively good as
potential solutions, they have certain limitations in transfer distance, efficiency, design, safety, and cost-effectiveness. This is
the reason why wireless power transfer has not yet been implemented on a mass scale in real-world products and in e-vehicles,
in particular. "

Same efficiency if coils are misaligned
For CES, Reasonance presented as one of its prototypes a fully
wireless 40 " TV powered with 120W. For demonstration purposes the receiving coil is placed on the back panel, though for
the product itself it can be incorporated inside. The transmitting
system is placed horizontally with an angle of 90 degrees at the
distance of about 50 cm, which means misalignment and angles
change between two coils are not a problem anymore. Due to
the patented configuration of the transfer system, it offers high
performance in power, efficiency, transfer distance, and design
freedom.
