An Integrated Tactile-Thermal Robot Sensor With Capacitive Tactile Array

A capacitive tactile sensor and a thermal sensor that can be combined into one compact device with both modalities are illustrated. The tactile sensing portion is composed of an 8 8 array of capacitive cells. By using as thermoresistors the rows’ traces of the matrix of the capacitive tactile array sensor thermal sensing is obtained. This allows the detection of the gradient of the temperature....

An integrated tactile and thermal sensor

The design, construction, and performance of a tactile sensor and a thermal sensor that can be combine into one compact device with both modalities is discussed. The tactile sensing portion is composed of an 8 x 8 array of force sensing cells with 1.8 mm center to center spacing. Heat transduction is measured by a 4 X 4 array of temperature sensors. A number of these devices will be mounted on ...

Psychological tactile sensor structure based on piezoelectric nanowire cell arrays

To produce artificial psychological feeling, especially ‘pain’, an electrical structure that mimics human skin has been studied. Touch by a sharp and a blunt object induces different deformations of the skin of human fingers. In order to imitate this phenomenon, a skin-mimicking device employing piezoelectric nanowire sensor arrays is used to generate an electrical ‘pain’ signal with signal pro...

Design and Construction of a New Capacitive Tactile Sensor for Measuring Normal Tactile Force

This paper presents the design, construction and testing of a new capacitive tactile sensor for measurement of normal tactile force. The operation of proposed sensor has been investigated in ASTABLE and MONOSTABLE circuits. According to the results of these circuits the deviation of ASTABLE circuit results is less than MONOSTABLE circuit results. In addition, the results obtained from ASTABLE c...
