Contact localization from soft tactile array sensor using tactile image

Industrial Robot: the international journal of robotics research and application
Purpose This paper aims to estimate contact location from sparse and high-dimensional soft tactile array sensor data using the tactile image. The authors used three feature extraction methods: handcrafted features, convolutional features and autoencoder features.

An integrated tactile-thermal robot sensor with capacitive tactile array

IAS '95. Conference Record of the 1995 IEEE Industry Applications Conference Thirtieth IAS Annual Meeting, 2002
The paper discusses a tactile sensor system with high sampling resolution integrated with a thermal sensor. The integration is performed by using the column armature of the matrix of a capacitive tactile sensor as thermal resistor having positive temperature coefficient. A prototype of the sensor has been designed and constructed.

Effect of sensor size in robotic tactile sensor arrays

Robotica, 1988
SUMMARYThe degree to which a binary tactile (or visual) image matches the original object is limited by the resolution of the sensor array. Given this fundamental limitation it is still possible to minimize the error in the image formed by the interconnection of the centers of activated sensors along the object's edge.

Face-shear mode ultrasonic tactile sensor array

2012 IEEE International Ultrasonics Symposium, 2012
Ultrasonic sensors using piezoelectric resonators are widely used for the chemical and biomedical applications because of their high sensitivity to applied loads, simple structures, and relatively low cost. In this study, we investigated an ultrasonic tactile sensing array using face-shear mode PMN-PT single crystal resonators, based on the sensing ...

POSFET Tactile sensor arrays

2007
In this paper, we present POSFET (Piezoelectric – Oxide-FET) based tactile sensing arrays. The equivalent model of a POSFET and its SPICE implementation is presented and various factors involved in the design of POSFET are discussed. A 5x5 array of POSFET tactile elements designed on the basis of discussion is also presented.

Some peculiarities when interfacing resonance tactile array sensors

2017 XXVI International Scientific Conference Electronics (ET), 2017
Tactile resonance sensors are characterized with high sensitivity [1] but their physical principles often place restrictions over the operational modes and the format of the obtained data. The current work is concerning itself with the interfacing particular resonance piezoelectric sensor array structure as the inherent features are explored for ...

Capacitive tactile sensor array for touch screen application

Sensors and Actuators A: Physical, 2011
Abstract In this paper, we propose and demonstrate a transparent and flexible capacitive tactile sensor which is designed for multi-touch screen application with force sensing. A sensor module is composed of 2D array tactile cells with a spatial resolution of 2 mm to measure the touch force at multiple positions.
