Transmission d’énergie par induction électromagnétique en plastronique 3D

Abstract : The objective of this thesis is to evaluate the interest of 3D molded interconnect devices technologies 3D-MID for wireless power transfer (WPT) through electromagnetic induction. WPT systems mostly uses planar coils that allows transfer between receiver and emitter at low and mid-range distance, at the condition that they are well aligned. We studied a specific case with a 3D receiver enclosed in a half meter box with 4 emitting inductors on 4 sides. Three questions were examined: the magnetic resonance of 3D-MID inductors at 6.78 MHz, their dimensions and their 3D shape. The nearly spherical shape 3D-MID receiver (Ø 8 cm) was 3D printed, activated with laser direct structuring (LDS), autocatalytic metallization and electroplating. It has 3 solenoid receiving inductors, each with quality factor above 129 ±10, placed orthogonally on the equators. The experimental results show: (1) the receiver is able to receive 4.33 W at 15.8 % efficiency in the middle of the box and (2) that we can change position and orientation of the receiver in the box, the placement of the inductors allows, in a widely meaning, to mean the received power. In conclusion 3D-MID allows to integrate, relatively easily, inductors for WPT, in the casing of electronics devices, in the same way as for 3D-MID electromagnetic antennas in smartphones. These inductors can 3D-shape the casing, which will allow the design of omnidirectional receivers
