Structural health monitoring involves periodic observations to monitor material and geometrical variations in constructions and structures. For reliable measurements, instrumentation must be set in perfect reproducible conditions. Printing sensors directly on the part to be controlled is the solution promoted in this study. This method solves the reproducibility issue, limits the Human factor influence, and leads to sensors that can be used in confined or hazardous environments.
This work was intentionally limited to eddy current testing sensors. Still, the printed-developed techniques and the conclusions are transposable to other non-destructive testing methods (ultrasounds, electromagnetic acoustic transducer, etc.).

In this paper, a cylindrical energy harvester, which combines an anti-vibration rubber and PVDF, and its characteristics evaluation method is presented. A forced vibration test using a hydraulic servo dynamic testing machine was conducted to determine the power generation characteristics. As a method to evaluate the power generation performance, a characteristic evaluation method was developed based on the governing equation of longitudinal vibration of the bar, and the results were compared with the experimental results to confirm the validity of the characteristic evaluation method.

A mesh deformation technique based on affine transformation is proposed to avoid re-meshing in this paper. To promote the speed of mesh generation, an improved mesh smoothing method is proposed in the initial mesh generation. An affine transformation is used to realize the mesh deformation. Magnetic field calculation of an induction motor is used to test the proposed method. The numerical results demonstrate that the proposed method can obtain a qualified mesh without re-meshing in small deformation.

In order to prototype a waveguide bandpass filter (BPF) using a 3D printer and plating, we proposed a new window structure and used μGA (micro Genetic Algorithm) for its design. From the design results, it was confirmed that the proposed structure can also obtain filter characteristics.
