Design and Experiment of a Flexible Array Tactile Sensor

2020
With the continuous improvement of robot intelligence, machine tactile and machine vision technology have been greatly developed, but most tactile sensors can not meet the requirements of tactile sensing applications. Therefore, piezoresistive effect and force information detection principle based on new sensitive materials are proposed, and a flexible

Fault tolerant tactile sensor arrays for prosthesis

2016 6th IEEE International Conference on Biomedical Robotics and Biomechatronics (BioRob), 2016
The demand for sensor networks has grown significantly over the last decade. These networks operate as a single unit, accumulating information from individual sensor nodes. Due to a matrix-like topology of these arrays, a fault at a single node may affect the performance of neighboring sensors. Therefore, it is critical to detect and compensate faults.

Slip classification for dynamic tactile array sensors

The International Journal of Robotics Research, 2015
The manipulation of objects held in a robotic hand or gripper is accompanied by events such as making and breaking contact and slippage, between the fingertips and the grasped object and between the grasped object and external surfaces. Humans can distinguish among such events, in part, because they excite the various mechanoreceptors in the hands ...

A tactile array sensor layered in an artificial skin

Proceedings 1995 IEEE/RSJ International Conference on Intelligent Robots and Systems. Human Robot Interaction and Cooperative Robots, 2002
Although major research efforts were devoted in the past to the development of tactile sensing systems for robots, a truly usable, robust, reliable and cheap system is not available yet. This paper presents the design of a tactile sensor system which could fulfil the above requirements.

Psychological tactile sensor structure based on piezoelectric sensor arrays

2017 IEEE World Haptics Conference (WHC), 2017
Recently, artificial tactile sensors have been studied in attempts to mimic the human sense of touch for various applications, from the simple input function of mobile devices to the complicated finger systems of android robots. To produce artificial psychological feeling, especially ‘pain’, electrical mimic structure of human skin has been studied ...

An Optical Tactile Array Sensor

SPIE Proceedings, 1985
This paper describes a new type of tactile sensor intended for robotic applications. It is based upon the frustration of total internal reflection at an optical surface caused by an opaque elastic membrane. An optical image is created in which the intensity is monotonically related to the strains or pressures created by an impressed object.

Biomimetics Microfluidic Tactile Sensor Array

ASME 2008 3rd Frontiers in Biomedical Devices Conference, 2008
Tactile sensors are the interfaces to detect the physical properties of objects and have extensive applications in robotic sensing, biomechanics, minimally invasive surgery and human prosthetics [1]. For human prosthetics applications, the current prosthetic hand can offer only the manipulation function.

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.
