These unknown vibrations
Long ago, the most known vibrations were the ones generated by the beats of church bells propagating in the air positive news to fight negativity.
In this moment in time however, tennis players from all over the world are mostly interested in those generated from the contact of two bodies, the ball and the racket.
In fact, the impact between the ball and the strings generates a broad spectrum of vibrations which are all transmitted to the frame of the racket, a stiff part, that transfers them through the arm to the body with multiple consequences.
FLUENDO has been studied to intercept and scatter the energy produced form the vibrations before vibrations multiply reaching the most critical point, which is the shaft right before the throat meets the handle.
As a matter of fact, it’s a dampener of the vibrations specific to tennis rackets, covered by the PCT international patent. FLUENDO is made with a polymeric silicone both nontoxic and hypoallergenic for biomedical use.
Its technology of HTV production makes it resistant to mechanical solicitations, to chemical attacks by UV rays and natural ageing (oxidation).
Furthermore, the device has an elastic module of over 400% and a memory shape that enables it to endure prolonged expansion and stretching without losing surface tension. All those factors guarantee its mechanical performance and make it unique in the absorption of these type of vibration waves.
Vibration decay curve
The main feature of FLUENDO lies in its ability to reduce the racket oscillation/vibration time from 1000 milliseconds to 820 milliseconds, also reducing the intensity of the peak vawes and lowering the absorption threshold of vibrations.
In BLUE is highlighted the racket with the FLUENDO device on, in GREEN the one without it.
After the impact of the ball on the racket strings (point 0), in the first 100 milliseconds there is a difference estimated at 6 dB (vibration more than halved) which at 500 milliseconds becomes 8 dB until reaching the widest peak at the end of the stress with a final gap of 9 dB.
