振动触觉阈值被确定为频率，接触器配置和接触器面积的函数。结果发现，接触面积是一个更重要的刺激参数比梯度或曲率的位移。当使用非常小的接触器时，振动的绝对阈值似乎与频率无关，而在低频时与面积无关。对于这些参数的较高值，它强烈地依赖于两者。这似乎是合理的结论，皮肤的机械位移的反应是由一个以上的受体系统介导的，虽然直接的证据仍然缺乏。
Vibrotactile thresholds were determined as a function of frequency, contactor configuration, and contactor area. It was found that contactor area is a more important stimulus parameter than the gradient or curvature of displacement. The absolute threshold for vibration seems to be independent of frequency when very small contactors are used and independent of area at low frequencies. For higher values of these parameters, it strongly depends on both. It seems reasonable to conclude that responses to mechanical displacement of the skin are mediated by more than one receptor system, although direct evidence is still lacking.
