Summary: This work reports the synthesis of Bi1-xSrxFeO3 (SBFO; x = 0.0, 0.15, 0.25, 0.35) nanoparticles by solgel method and investigates their structural and piezoelectric properties. The study reveals the phase transformation from rhombohedral to cubic of BiFeO3 upon Sr doping, as well as the enrichment of oxygen vacancies in Sr-doped BiFeO3 nanoparticles. The SBFO-PENG device with 25% Sr content shows the highest maximal polarization value and remnant polarization, along with improved output voltage and current compared to a bare BiFeO3 PENG. It also demonstrates high mechanical robustness and stable output even after extended periods of operation.

Summary: This study proposes a human-friendly biomechanical energy harvester that utilizes a cooperative compliant traction mechanism. The harvester is driven by the knee joint through a compliant medium without any mechanical components, adding no weight or restraint to the knee joint. The harvester works in collaboration with the user's walking/running, collecting energy when the user does negative work. The use of frequency up-conversion and mechanical rectification improves the efficiency of electromechanical conversion. The prototype of this HF-BEH can generate power with little impact on mobility, and it has been shown to enable self-powered emergency call, positioning and tracking, health monitoring, and physical therapy. Human-vehicle interaction through self-powered wireless sensing based on HF-BEH has also been demonstrated to improve the safety of individuals with limited responsiveness and mobility in traffic environments.
