To maximize the harvesting power, the resonance frequency of the PEH should match the dominant frequency of the ambient vibrations. In article number 2205179, Kyung-Hoon Cho, Hyun-Cheol Song, and co-workers report a novel autonomous resonance-tuning (ART) PEH that autonomously adjusts its resonance frequency in accordance with ambient vibrations without any external assistance or human intervention. The PEH design methodology to implement the ART function is provided along with its real-world validation under low-frequency (<100 Hz) complex vibrations in which the acceleration and frequency change simultaneously.
