Positioning of Actuators within Tactile Functions
Various actuators are used for tactile functions. "Notification" uses eccentricity motors, linear resonance actuators, and other electromagnetic actuators, while "force feedback" utilizes piezoelectric actuators in addition to such electromagnetic actuators. The subsequent "tactile sensation" requires piezoelectric actuators with a broad drive frequency band and a quick response speed.
ADVANTAGE
Advantages of the "Piezoelectric Actuators" from TAIYO YUDEN
CASE STUDY
Piezoelectric Actuators can accommodate various applications such as fluid control, acoustics, vibration control, cooling, and ultrasonics through the direction of displacement. In particular, TAIYO YUDEN actuators possess superior characteristics for high displacement and low power consumption due to the material technologies, the lamination, and film lamination technologies.
