Bidirectional active piezoelectric actuator based on optimized bridge-type amplifier

HIGHLIGHTS

  • who: Weiqing Huang et al. from the School of Mechanical and Electrical Engineering, Guangzhou University, Guangzhou, China have published the paper: Bidirectional Active Piezoelectric Actuator Based on Optimized Bridge-Type Amplifier, in the Journal: Micromachines 2021, 1013 of /2021/
  • what: In this paper a series mechanism is proposed to realize a drive; the return stroke is driven by a stack rather than by the flexibility of the structure.
  • how: The following relation can be obtained FAx=FBx=Fin /2 𝐹 𝐹 where Fin represents the input force of the bridge mechanism.
  • future: When . . .
