Associate Professor Atsutoshi Ikeda and his research team at Kinki University have made a remarkable discovery regarding the optimal placement of sensors within a visualization system that captures the nuances of fingertip sensations. By employing a 3D scanner, they meticulously measured the extent of deformation in the fingertips of both men and women. Their findings unequivocally demonstrated that the sensor’s placement on the abdominal side of the finger maximized the system’s sensitivity in accurately estimating tactile perception. This groundbreaking system, capable of quantitatively measuring the sensations in our fingertips, holds tremendous promise in preserving the cherished technical traditions of master craftsmen.

Dr. Ikeda and his esteemed colleagues are diligently developing a cutting-edge system that employs microelectromechanical system (MEMS) sensors to measure the deformation on the abdominal side of the finger. This advanced system aims to precisely estimate the forces applied to the fingertips and their corresponding sliding directions. Through the strategic placement of two force sensors on either side of the finger pad, the team gathers the essential data required for their research.

Our sense of touch is an invaluable aspect of our daily lives. However, the challenge lies in effectively sharing and accurately communicating this intricate sense with others. By enhancing the sensitivity of this fingertip sensation measurement system and shedding light on the skill acquisition process of accomplished craftsmen and athletes, we hold the potential to quantitatively evaluate our own tactile perception and efficiently master new skills.

Moreover, by measuring the tactile acuity of highly skilled veterans and quantifying their expertise, we anticipate a substantial reduction in the time required for vocational training programs, including the onboarding of new employees.
