➀ Researchers at Northeastern University in China have developed an H-shaped bionic robot that mimics a cheetah’s running motion using piezoelectric materials.

➁ The H-shaped bionic piezoelectric robot (H-BPR) features four legs connected by three piezoelectric beams, allowing it to mimic a cheetah’s gait through periodic leg movements.

➂ Experiments showed the robot could achieve a maximum velocity of 66.79 mm/s and a load capacity of 55 g, demonstrating potential for industrial applications and search-and-rescue missions.

➀ The study introduces a capillary effect-based sealing strategy to address air leakage and asynchronous vibration issues in piezoelectric MEMS speakers. ➁ This method uses PDMS liquid to autonomously seal the narrow gaps in the speaker structure, improving low-frequency and resonant frequency sound pressure levels. ➂ The sealed speakers showed a 4.9 dB increase in sound pressure level at 20 Hz and a 17.5 dB improvement around the resonant frequency, with minimal impact on other frequency performance.
