We developed a wearable sensor system for estimating the contact force by measuring the mechanical deformation in fingertip. The first part of this paper describes the design criteria of the wearable sensor system based on previous studies and our experimental result on the deformation behavior of the fingertip when pressed. Then we propose a sensor system for measuring the finger deformation with a simple wearable fixture. Moreover we propose two calibration methods for estimating the contact force of the fingertip with allowing the individual difference of the finger size. Our proposed sensor system can be widely utilized for evaluating the haptic procedure when people examine the haptic perception or usability of an object without constraining their behaviors in daily life.
