STReSS
Introduction
The is a 2D laterotactile display that stimulates the fingertip with a matrix of miniature piezoelectric bending actuators. The latest revision is composed of 64 actuators in an 8 by 8 matrix. An earlier revision had 60 actuators in a 6 by 10 matrix. In both cases, the active area of the tactile display is slightly smaller than the average fingertip (approximately 1 cm2). This tactile display is the result of sustained efforts over more than a decade by a number of graduate students in the Haptics Laboratory. Earlier generations of the tactile display can be found in the publications below.
