Abstract. We propose a shielding technique for the magnetic field localization around permanent magnets (PMs) for sharpening the magnetic force-displacement curve in the frequency up-conversion (FuC) of piezoelectric vibration energy harvesters (PVEHs). We present a concept with theoretical formulation, computational analyses, and experimental validation that confirms the supposed principle. The numerical study on a PVEH shows that with the shielding, for varying actuation velocity, high values of peak power (50 mW – 150 mW) can be reached at low speeds (e.g. 0.5 m/s – 2.6 m/s). The unshielded device exhibits a good behavior for velocities over 3 m/s. This result makes the technique useful for the design of FuC mechanisms depending to its operating velocity.
