An all digital VLSI tactile array sensor

Proceedings. 1984 IEEE International Conference on Robotics and Automation, 2005
This paper describes a new VLSI tactile array sensor that was designed for use on the fingers of a robot manipulator. The photolithographic methods used in fabricating the microelectronics were also used to build an array of mechanical structures on top of an integrated circuit.

A Flexible Tactile Sensor Array Based on Conductive Rubber

2019 IEEE International Conference on Robotics and Biomimetics (ROBIO), 2019
In this paper, a novel flexible tactile sensor array based on conductive rubber is presented. Compared with other research results, we use the materials with complete flexibility to fabricate the soft sensors. The sensing prototype includes polydimethylsiloxane (PDMS) as the sealing layers and conductive rubber as sensing layer.

Tactile array sensor for manipulator based on the barometric chips

2017 IEEE 60th International Midwest Symposium on Circuits and Systems (MWSCAS), 2017
This article presents a new method of using barometric chips to make tactile array sensor for manipulator. The barometric chip can detect and convert analog air pressure to digital signal and calculate the value of surface air pressure. First we design appropriate circuits with the PCB technology and mount the chips on the board, then we manufacture a ...

Object recognition using tactile image array sensors

Proceedings. 1986 IEEE International Conference on Robotics and Automation, 1986
The objective of this paper is to develop an object recognitlon system through the combination of 2-D tactile image array and visual sensors. A video camera is used to acquire a top view image of an object and two tactile sensing arrays mounted on a gripper are used to detect the tactile information about the lateral surfaces of the object.

Piezoelectric Polymer Transducer Arrays for Flexible Tactile Sensors

IEEE Sensors Journal, 2012
In this paper, we propose a novel technological approach for the implementation of large-area flexible artificial skin based on arrays of piezoelectric polymer transducers. Polyvinylidene fluoride (PVDF) transducers are chosen for the high electromechanical transduction frequency bandwidth (up to 1 kHz). A low-cost and scalable technique for extracting

A capacitive tactile sensor array for surface texture discrimination

Microelectronic Engineering, 2011
This paper presents a silicon MEMS based capacitive sensing array, which has the ability to resolve forces in the sub mN range, provides directional response to applied loading and has the ability to differentiate between surface textures. Texture recognition is achieved by scanning surfaces over the sensing array and assessing the frequency spectrum ...

Microstructured Graphene Arrays for Highly Sensitive Flexible Tactile Sensors

Small, 2014
A highly sensitive tactile sensor is devised by applying microstructured graphene arrays as sensitive layers. The combination of graphene and anisotropic microstructures endows this sensor with an ultra-high sensitivity of -5.53 kPa(-1) , an ultra-fast response time of only 0.2 ms, as well as good reliability, rendering it promising for the application

Effects of the elastic cover on tactile sensor arrays

Sensors and Actuators A: Physical, 2006
Tactile sensors are composed of two substantial parts, the sensory structure and its cover. The characteristics of a sensor are fundamentally set by the sensor design, but are also essentially modified by the elastic cover on top. In this paper we analyze the pure mechanical information-coding effects of the sheltering rubber layer, applied on single ...
