Itch is an unpleasant sensation associated with various disease, and can trigger scratching. Management of itch and scratching is important for treatment of disease. Therefore, quantitative and objective evaluation of itch and scratching is demanded. This work aims to develop the sensor system for evaluating the scratching motion. For the purpose, we focus on scratch sounds induced by scratching motion and, propose a nail mounted sensor system . In the sensor system a small microphone is attached on a nail for measuring scratching sounds. First, for investigating the relationship between the scratch sounds and the mechanical characteristics of human scratch motion, the artificial skin model made of polyurethane was used as a scratched object. The measurement system that can measure force and a motion of fingertip during scratching was constructed. Using the measurement system, various kinds of human scratch motions and sounds were measured. By signal processing of the scratch sounds, the several sound features were calculated and characteristics of scratch motions were extracted. Then, correlation coefficients between sound features and scratch motion properties were calculated. From the results, two pairs of the parameters were found as the most adequate parameter pair to evaluate the mechanical characteristics of human scratch motion. And using these parameters, “scratch evaluation map” was proposed as a method to evaluate the mechanical characteristics of human scratch motion. From the results, it was found that the developed sensor system has possibility to evaluate the mechanical characteristics of human scratch motion by the scratch sounds.

ヒトの触感にどのような因子が強く関わるかを、物理パラメータが既知な対象物の製作、さらにそれらを用いた官能調査やヒトの触動作測定、受動触刺激等による評価を通して、調査した。これらの知見を基に皮膚の感覚受容器の特性と触動作を、センサ材料、駆動機構ならびに信号処理方法により実現し、しっとり感、ふんわり感、温冷感、ぺたぺた感、きゅきゅっと感などの多機能な触感計測を可能とするセンサシステムを開発した。

This paper is a study on the valuation and mathematical formulation of human touch sensation. First, the feelings of touch are collected on five natural and chemical fabrics through the SD (Semantic Differential) method questionnaires sent to twenty three examinees. The feelings are valued on each fabric by using the weigthed mean on graded factor feelings. The multiple regression analysis is then introduced to represent the overall evaluation of touch on every fabric by a linear function of the valuations on feelings of touch. Next, a soft tactile sensor made of a PVDF (Polyvinylidene Fluoride) film patch and rubber layers is assembled and slid over the same sample fabrics to collect the surface tactile information on the fabrics. The features on the collected data are then extracted by calculating the temporal average of absolute out signal and using the intensity of power spectral density on the medium frequency range. Comparison of the results show that the PVDF sensor well describes the tactile perception of forefingers.
