“…While electromagnetic converters have been used since the beginning of the energy harvesting era, they still offer great opportunities for innovations and optimizations. For example at the system scale, such as in water flow energy harvesting [8,9], high-G shock energy harvesting [10], electrodynamic wireless power transmission [11,12], biomechanical energy harvesting [13,14], or vibration energy harvesting [15,16]. But also at the material scale, for example with the use of injection molded magnets to optimize the shapes, the performances and the ecological footprints of electromagnetic converters thanks to magnet recycling opportunities [17,18].…”
