Civionics
Encyclopedia
Civionics is the combination of civil engineering with electronics engineering, in a manner similar to avionics
(aviation and electronics) and mechatronics
(mechanical engineering and electronics). An emerging discipline, the main application area of civionics is currently the use of electronics for structural health monitoring
(SHM) of civil structures, particularly photonics
(Fiber Optic Bragg Grating).
In SHM, Civionics will provide engineers with feedback necessary to aid in optimizing design techniques and understanding infrastructure performance, behaviour and state of condition. The successful integration of intelligent sensing of innovative structures will allow civil structural engineers to expand the design envelope by taking risks to introduce new design concepts, materials and innovation in civil engineering.
Civionic engineering applications include integrating science and technology from both new and traditional disciplines:
Avionics
Avionics are electronic systems used on aircraft, artificial satellites and spacecraft.Avionic systems include communications, navigation, the display and management of multiple systems and the hundreds of systems that are fitted to aircraft to meet individual roles...
(aviation and electronics) and mechatronics
Mechatronics
Mechatronics is the combination of mechanical engineering, electronic engineering, computer engineering, software engineering, control engineering, and systems design engineering in order to design, and manufacture useful products. Mechatronics is a multidisciplinary field of engineering, that is...

Structural health monitoring
The process of implementing a damage detection and characterization strategy for engineering structures is referred to as Structural Health Monitoring . Here damage is defined as changes to the material and/or geometric properties of a structural system, including changes to the boundary conditions...
(SHM) of civil structures, particularly photonics
Photonics
The science of photonics includes the generation, emission, transmission, modulation, signal processing, switching, amplification, detection and sensing of light. The term photonics thereby emphasizes that photons are neither particles nor waves — they are different in that they have both particle...
