HapLog Finger Tactile Sensor

Content

HapLog sensor is a “sensor that measures natural finger operations” with a built-in contact force sensor and a 3-axis acceleration sensor.

This sensor allows for measurement of the force used when grabbing an object and the force used when using an object with your fingers. In addition, thanks to the built-in accelerometer, momentum is also measurable. The sensor doesn’t cover the fingerprint area of the finger pad, so measurement of natural behaviors can be achieved without any loss of tactile sensation.

Researched and developed the idea of working with Shiseido in the creation of a fingertip sensor. Such a sensor would have an impact on cosmetics and skin care products because these products are applied to the skin. In addition, depending on how force is applied, each person will have a different feeling of use. These differences are impossible to explore through a questionnaire. That led to the development of the HapLog sensor, which allows for operation without any loss of tactile sensation. The HapLog Wearable Contact Force Sensor allows operations from general users to be compared with operations by professionals in order to visually convey the characteristics of an individual's tactile behaviors.

Features

The sensor does not cover the pad of the finger, allowing for operation that does not compromise sensation.

Calibration

Every finger is different, from size to the thickness of the skin. For this reason, calibration of the contact force and deformation amount should be performed before every measurement. The HapLog system is designed so that personal data can be created in as little as 2 to 3 minutes.
