Tactile sensation is perceived through deformation of the skin. Therefore, transmission of stimuli applied to the skin is an important factor for tactile perception. This paper presents the measurement of skin-transmitted vibration characteristics on human fingertip. Sinusoidal stimuli are applied on the finger pad and skin-transmitted lateral and longitudinal waves are measured by an audio cartridge placed at the skin surface of the fingertip. Measurements are conducted on a human finger, a human finger covered with collodion film, and water bed model of human finger. In addition, measurements are conducted on human fingers whose nails are bended. The results suggest that human fingertip has a resonance frequency among 200〜260 Hz on the skin-transmitted longitudinal waves and the characteristic is changed by bending the nail.
