It is a "sensor that measures natural finger movements" equipped with a contact force sensor and a 3-axis accelerometer.
We can measure the force when grasping an object and the force when using the fingers to perform actions. Additionally, since it is equipped with an accelerometer, it can also measure movement. Because it does not cover the fingerprint area of the fingertip, it allows for natural movements to be measured without compromising the actual tactile sensation. 【Co-developed Product】 Shiseido Co., Ltd. × Catotech Co., Ltd. Catotech has been conducting research and development with Shiseido to see if we can turn fingertips into sensors. The way cosmetics and skincare products are applied to the skin can affect their effectiveness. Moreover, the amount of force applied can lead to differences in the user experience. It was impossible to explore such differences through customer surveys. Therefore, we have been advancing the development of sensors that allow for actions without compromising the tactile sensation of the fingertip. HapLog enables the analysis of actions by general monitors and comparisons with professionals, making it possible to visually convey the characteristics of individual tactile movements.

basic information
● What is the mechanism of sensing? It detects the deformation of the fingertip when the finger comes into contact with an object. The fingertip deforms horizontally when it touches an object. The sensor detects this deformation and measures the magnitude of the force. Before measurement, the sensor performs calibration in advance to correct the relationship between the contact force, which varies among individuals, and the deformation of the finger. Additionally, it has a built-in 3-axis accelerometer, allowing simultaneous measurement of the movement of the finger with the sensor attached. ● The sensor does not cover the fingertip, allowing operation without compromising tactile sensation. ● It has a built-in 3-axis accelerometer to measure momentum in three directions. ● Lightweight and can be worn on the arm. Despite its small size, it can sense three fingers simultaneously. ● Rapid calibration. The relationship between the deformation of the fingertip, which varies among individuals, and the contact force is corrected in advance through calibration.
