Improvement of Vibration Sensitivity by Tangential Vibration
A vibration sensitivity is usually defined by the minimum amplitude when a subject perceives the vibration with ω 1 which is the frequency of perpendicular direction on the skin surface. In this work, we are interested in how the vibration sensitivity at ω 1 is changed under the condition adding the...

| Summary: | A vibration sensitivity is usually defined by the minimum amplitude when a subject perceives the vibration with ω
1
which is the frequency of perpendicular direction on the skin surface. In this work, we are interested in how the vibration sensitivity at ω
1
is changed under the condition adding the tangential vibration with ω
2
which is the frequency of tangential direction on the skin surface. Through all experiments, we found that the vibration sensitivity at ω
1
= 8, 10, and 25 Hz is improved approximately 30% with the
p
-value of below 0.1% by an adequate setting condition of ω
2
= 3 Hz. |
