Since the volume of the proposed actuator
(141.3mm
3
) is smaller than that of commercial linear
resonance actuators (360 mm
3
), the proposed
actuator can be easily embedded in mobile devices.
3 CONCLUSIONS
In this paper, we presented a tiny vibrotactile
actuator, which is easily embedded into mobile
devices, consisting of the moving part, two solenoids,
a steel housing, and two covers. Since the proposed
actuator provides enough working frequency and
output force to stimulate human skin, it can
selectively stimulate human’s mechanoreceptors.
According to the current input, the moving part runs
from the initial position to the other end and collides
with a silicon bumper attached to the end of the
solenoid coils in order to generate vibration. Our
work underscores the importance of the proposed
haptic actuator to enable users to experience
immersion while interacting with mobile devices.
