This paper reports the initial experimental results of a wearable sensorimotor enhancer for a fingertip. A short-time exposure of tactile receptors to sub-sensory white-noise vibration is known to improve the tactile sensitivity. This phenomenon, called ``noise-enhanced tactile sensation'' or stochastic resonance (SR) in the somatosensory system, is expected to enhance the sense of touch of a fingertip, and thereby improve associated motor skills. In this paper, a prototype sensorimotor enhancer has been developed. The wearable device is to stimulate tactile receptors by applying white-noise vibration from a compact lead zirconate titanate (PZT) piezoelectric stack actuator attached at the radial side of the fingertip. This design keeps the palmar region free and maintains the wearer's manipulability. Sensory and motor tests have been conducted for health subjects to confirm the efficacy of the device. Statistical significance has been observed in most of the tests.
