Wireless Hibernation Network free4act

In medical applications , it is necessary to assess some objective measurements of kinematic characteristics of various body parts , and the kinematic characteristics of the body as a whole, in order to identify potential problems or to assess the effectiveness of a treatment. In this context, the analysis of gait is a useful tool for the quantitative assessment of the results of a surgery to assess the patient’s condition , as well as φορ selecting the best treatment.


There are many reliable methods for assessing the motion of a patient. The most popular are φοοτ-scanners and optoelectronic systems .

However , even today , few medical centers use these devices, while the methodology is still too τιμή consuming, it takes a lot of space and has α limited scope for diagnosis. To these features it should be added the fact that the measurements are made in the artificial conditions of the laboratory , where the person being tested may react very differently than in everyday life.

Movement analysis works better with small, cheap and easy to carry devices that do not affect the normal activity of the individual.

Our team developed a wireless measurement system for assessing exercises and kinematic activity and performance diagnostics without the limitations of laboratory tests.

These features allow the use of inertial sensors to continuously study the movement outside the laboratory.




The Free4Act is a wireless network inertial sensor, constructed specifically for evaluating the movements of the person.


The sensors connect to a data recorder (up to 16 sensors) via a ZigBee radio transmission unit . Each sensor can be configured to contain an accelerometer, a magnetic field sensor and a gyroscope.
