Albert Einstein's Theory of General Relativity in 1916 described a universe through its equations, where space and time are dynamic. Einstein suggested that matter and energy change the geometry of space-time through the effect of gravity. The speed of gravity is one of the great mysteries of nature and one of the most difficult to be discovered, because trying to obtain this value through observation of astrophysical objects is almost impossible to isolate the speed of gravitation and the

The development of the detection and transduction system is the focus of this research project where 3 sapphire bars will be suspended at 1 meter between them; the central sapphire will be the receiver of the electromagnetic signals, while the two "external" sapphires will transmit these electromagnetic signals by means of a PZT (piezoelectricity) system. In the calculations made in this project the sensitivity is sufficient to measure the signal. Key words: Detection of gravitational signals, Control and magnetic suspension, PZT-piezoceramic technology and Sapphire.
