Mechanoluminescent Contact Type Sensor

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...

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...

Contact sensor-based Coverage of Rectilinear Environments

A variety of mobile robotics tasks require complete coverage of an initially unknown environment, either as the entire task or as a way to generate a complete map for use in further missions. This is a problem known as sensor-based coverage, in which the robot's sensing is used to plan a path that reaches every point in the environment. Sensor-based coverage algorithms have been developed previ...

Mechanoluminescent light source for a fluorescent probe molecule.

We have demonstrated an innovative ability of mechanoluminescent (ML) material as a light source for the first time. By appropriate smart size control and nondestructive mechanical stimulation, the ML particle can be considered a promising candidate of in situ light source for bio-imaging and photo-therapy even in a human body.
