Tactile sensor which displays contour lines on contact.

Design and Construction of a Novel Tactile Sensor for Measuring Contact-Force, Based on Piezoelectric Effect

In this paper, design and construction of a tactile sensor for measuring contact-force is presented. Mechanism of measuring contact-force in this tactile sensor is based on impedance changing of piezoelectric crystal and voltage of different points in circuit as a result of applying force on the crystal. By considering a specific point in the circuit and recording the changes of its voltage, ma...

Design, Modeling, and Construction of a New Tactile Sensor for Measuring Contact-Force

This paper presents the design, modeling, and testing of a flexible tactile sensor and its applications. This sensor is made of polymer materials and can detect the 2D surface texture image and contact-force estimation. The sensing mechanism is based on the novel contact deflection effect of a membrane. We measure the deflection of the membrane with measuring the strain in the membrane with emb...

On the Accuracy of Tactile Displays

Inaccuracies in the reporting of finger positions from electronic tactile displays can result in errors in the audio presentation of multi-modal applications. In this paper, we conduct an experiment to examine the accuracy of one such device. Given the results of this experiment, we present a collection of recommendations for the spacing of objects within a tactile scene.
