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 gripping 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. It does not cover the fingerprint area of the fingertip, allowing 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 can affect their efficacy. Furthermore, the amount of pressure applied can lead to differences in the user experience. It was impossible to explore such differences through customer surveys. Therefore, we have been developing sensors that can operate without compromising the tactile sensation of the fingertip. HapLog enables motion analysis of general monitors and comparison of movements with professionals, making it possible to visually convey the characteristics of individual tactile actions.

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 of the fingertip and measures the magnitude of the force. In this sensor, calibration is performed beforehand to correct the relationship between the contact force, which varies among individuals, and the deformation of the finger. Additionally, since it has a built-in 3-axis accelerometer, it can simultaneously measure 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 through calibration in advance.
