SEISMIC DETECTION SYSTEM
ES2913295
A seismic detection system in a single device, comprising a first inner 3D polyhedral container (12), a triboelectric nanogenerator energy sensor device TENG (13) attached by a first outer surface (21) to a first outer surface of the first inner 3D polyhedral container (12) and by a second outer surface of the sensor TENG (13) is attached to a first outer surface of an inertial mass, a second outer surface of the inertial mass (14) is mechanically coupled to a first end of a spring and a second end of the spring (15) is mechanically coupled to a first inner surface of a second outer 3D polyhedral container (16). The spring (15) compresses the inertial mass (14) and the second outer 3D polyhedral container (16) encloses and protects a first deformation chain formed by the first inner 3D polyhedral container (12), the TENG sensor (13), the inertial mass (14) and the spring (15).
The geometrical features of this seismic detection system allow the detection and differentiation of seismic waves in the three spatial dimensions at larger frequency intervals that current individual devices used for this application. The device is able to detect and quantify different physical magnitudes of seismic waves such as velocity, acceleration, strength, displacement, frequency, allowing a thorough characterization of these waves. A diversity of materials has been employed to manufacture this device and tailor its design to different applications such as volcanoes (high heat and flame resistance), underwater (high pressure and corrosive environment), environments with high humidity, etc. Also, the system functions as a short-range wireless transmitter capable of communicating data signals in real-time.
