Stacked piezoelectric actuator (manufactured by NEC Tokin)
Stacked piezoelectric actuator (manufactured by NEC Tokin)
It is a ceramic element that converts electrical energy into mechanical energy such as displacement or force using the piezoelectric longitudinal effect.
- High-speed response (for piezoelectric elements in standalone or external mechanism connection: both at one-third of the resonance frequency) - Conversion efficiency from electrical energy to mechanical energy (approximately 60%) - High generated mechanical energy per unit volume (about 20 mJ per cm³) - Large generated force (approximately 3500 N per cm²) - Optimal as an energy source for displacement amplification mechanisms - High positioning resolution - Low driving voltage, easy to use

Company information
"Mechatrans" is a technology that I developed during my time at NEC in the 1980s, successfully realizing the world's first and fastest piezoelectric impact printer at that time. Subsequently, due to the evolution of printer technology, this technology disappeared from the public eye. However, Professor Toshio Higuchi from the University of Tokyo foresaw the potential of this technology, leading to the establishment of today's company. By leveraging the numerous advantages of the piezoelectric method, "Mechatrans" has achieved high-speed and large-displacement actuators, and I feel the potential for its use in a wide range of fields. We have now developed a series of actuators for everyone’s use.
