1 2011 November Shiseido Develops World s First Finger Sensor That Holds the Key to New Value Development of Cosmetic Products in Cooperation with Electronic Measurement Instrument Manufacturers Kato Tech and Tec Gihan The evaluation and affective preferences of cosmetic products have been largely influenced by the degree of finger pressure (tactile pressure) and movement when the finger comes into contact with the skin. At this time, Shiseido Co., Ltd. has developed world s first finger sensor that is able to simultaneously and precisely measure the pressure and movement of the finger when the finger comes into contact with the skin. Development was carried out in cooperation with electronic measurement instrument manufacturers Kato Tech Co., Ltd. (Head office: Minami-ku, Kyoto; hereinafter Kato Tech ) and Tec Gihan Co., Ltd. (Head office: Uji City, Kyoto; hereinafter Tec Gihan ). This development of a finger sensor elicits new value creation in relation to comfort and the satisfaction level of finish for cosmetics, which has not been well elucidated up until now. The finger sensor also will be linked to the unprecedented development of cosmetics and beauty methods that affect the emotional satisfaction of our valued customers. Background of Development The evaluation and preferences of cosmetic products largely depend on not only the cosmetic product itself but also finger pressure (tactile pressure), movement and rhythm when cosmetics are applied to the skin. However, there has been no device until now to measure tactile pressure and movement of the finger precisely when using cosmetics, and these aspects have therefore been studied by questionnaire surveys based on the evaluator s subjective opinion. Previous wearable finger devices cover most of the fingerpad surface and thus are not suitable to measure the tactile pressure when direct contact of finger occurs. In addition, with regard to devices to measure finger movement, separate devices have been usually required, and it has not been possible to measure subtle movements during cosmetic behaviors with these devices as well. Therefore, Shiseido believed that a device that can measure tactile pressure and movement of the fingerip at the same time was necessary, and launched the project for creating such a device. Development proceeded in cooperation with Kato Tech and Tec Gihan, which are companies with a proven track record in developing devices for measuring the touch feeling of clothes texture. The World s First Successful Venture to Develop a Finger Sensor The finger sensor is integrated with strain gauges to measure finger pressure and an acceleration sensor to measure subtle finger movement that are positioned so that the device can be attached to the fingernail side (Figure 1). Along with the high-sensitive acceleration sensor, the device achieves a world first sensor in being able to measure tactile pressure and movement at the same time when the finger makes direct contact with the skin or an object. A fingerpad displays the same characteristics as a water bag in that when the finger is vertically pressed, the fingerpad is horizontally deformed. This horizontal deformation of the fingerpad is measured in order to estimate the amount of contact force applied to the fingerpad. To improve the sensitivity of measurement, strain gauges are located on the finger fixture and the finger fixture touches both sides of the fingerpad with the right amount of tension, which is found to be important to not interfere with the horizontal deformation of the fingerpad. In addition, deformation of the fingerpad is different among individuals; therefore, an original adjustment procedure

2 has been developed at the same time. The method of being able to be attached the finger fixture to the fingernail and the use of the strain gauges positioned on both sides of the finger fixture, as well as a small acceleration sensor which detects finger movement with a high degree of precision, made simultaneous, accurate, even simple and quick measurement possible for recording quantitative data of the subtle movements and tactile pressure of the finger when cosmetics are applied to the skin (Figure 2). Future Development Going forward, Shiseido will utilize the finger sensor device for product development (cosmetics, containers, cosmetic tools and promotional appeals), beauty method development and improving beauty techniques. These research results have also been highly evaluated and have received a great deal of attentions at the world s foremost international conference* in the haptics research, along with having high expectations for application from various areas including medical rehabilitation, nursing care skills instruction, evaluating the usability of automobiles, mobile phone s and home electronics. This finger sensor won a Good Design Award in 2011 in Japan. Also, the finger sensor will be released by Kato Tech, which jointly developed the device, as the Wearable Contact Force Sensor HapLog (Haptic Skill Logger) ; planned price for the basic system : 1.2 million yen (excluding tax)), with sales commencing from the last week of November * Institute of Electrical and Electronics Engineers (IEEE), WORLD HAPTICS CONGRESS 2011 held in Istanbul, Turkey, in June 2011 <Evaluation from the Panel of Judges of Good Design Award> The area of haptics is a subtle and perception-based design field, and its individual empirical values are difficult to share with other persons verbally. This device is able to record the subtle movement of the user. The idea that the sensor is attached to the fingernail without covering the fingerpad is to be commended. If the device would be attached to the fingerpad, then the subtle tactile feeling could not be perceived;therefore, our judgment is that this device is highly valuable. We look forward to this sensor system creating a new design concept and research field.
