摘要：

Self-powered wireless sensing systems face a fundamental challenge in effectively harvesting multidirectional low-frequency vibrations—a dominant feature in environmental mechanical energy spectra—while maintaining compact form factors. Conventional energy harvesters often exhibit limited adaptability to multidirectional excitations and poor efficiency at low frequencies. Inspired by the adaptive petal morphology of flowers, this work presents a flower-like bidirectional energy harvester (FLB-EH) incorporating quasi-zero stiffness (QZS) mecha...
