Resistivity Characteristics of Piezoresistive Based Transduction Tactile Sensing Using Pressure Sensitive Conductive Rubber Sheet

چکیده
This paper presents the development of a tactile sensor based on pressure sensitive conductive rubber and outlines the resistance measurements performance. This sensor is specially designed for a robotic hand developed at UiTM Faculty of Mechanical Engineering. It exhibits piezoresistive like behaviour whose resistance change with force/pressure enables its applications as tactile sensor. The operating principle and hardware architecture of the sensor is explained. This study results in finding new alternative material selection for tactile sensor which needed more exploration and experimentation in order to discover their potential as tactile sensor for robotic hand as well as other field. In this paper, the working principle and sensor design concept are described. Further, experimental results and analysis of materials resistance characteristics are presented. The test results indicate significant drop of resistance with the increase of applied load.

Tactile Sensor Without Wire and Sensing Element in the Tactile Region using New Rubber Material
Recently the idea of covering a robot's surface with a ‘skin’ of soft tactile sensors has attracted the attention of researchers, and some human-interactive robots covered with such sensors have actually been made (Tajima et al., 2002; Kanda et al., 2002). However, most conventional tactile sensors need a large number of sensing elements and wires because every detection point needs one sensing...
متن کاملPiezoresistive Tactile Sensor Discriminating Multidirectional Forces
Flexible tactile sensors capable of detecting the magnitude and direction of the applied force together are of great interest for application in human-interactive robots, prosthetics, and bionic arms/feet. Human skin contains excellent tactile sensing elements, mechanoreceptors, which detect their assigned tactile stimuli and transduce them into electrical signals. The transduced signals are tr...
متن کاملDigital Tactile Sensing Elements Communicating through Conductive Skin Layers
In this paper, we propose a tactile sensing element that communicates through two dimensional conductive skin layers without individual wires. Each tactile element has sensors and signal processors, and it broadcasts coded tactile signals through a couple of conductive layers. Since the conductive layers can be used for both the electrical power supply and the communication, simply sandwiching ...
متن کاملProposal of A SkilMate Finger for EVA Gloves
It has been pointed out that the hard structure of an EVA glove deteriorates e±ciency of tasks in the space environment. We also found a claim that an EVA glove did not allow an astronaut to acquire contact information at the ̄ngertips. In the study, we proposed a SkilMate Hand for space EVA gloves which has both a tactile media and a power assist devices. We locate SkilMate in a wider framewor...
متن کاملMeasurement of Respiration and Heartbeat Using a Flexible Tactile Sensor Sheet on a Bed
We describe a measurement method of respiration and heartbeat using a Smart Rubber sensor, a rubber-based flexible tactile sensor sheet that we developed. This method is useful for unconstrained recording of a person sleeping soundly, sleeping lightly, lying down, sitting on a bed, and so on. Our goal is to monitor those who require nursing care. The proposed method measures respiration and hea...
