“…Some tactile sensors and small force sensors using microelectromechanical systems (MEMS) technology have been introduced. MEMS tactile sensing work has been focused mainly on silicon-based sensors that use piezoresistive [1][2][3] or capacitive sensing [4][5][6]. These sensors have been realized with bulk and surface micromachining methods.…”

Abstract-In this work we propose a new class of optical pressure sensors suitable for robot tactile sensing. The sensors are based on a tapered optical fiber, where optical signals travel, embedded into a PDMS-gold nanocomposite material. By applying different pressure forces onto the PDMS-based nanocomposite we measure in real time the change of the optical transmittivity due to the coupling between the gold nanocomposite material and the tapered fiber region. The intensity reduction of the transmitted light intensity is correlated with the pressure force magnitude.

“…Many different approaches have been proposed to fabricate these sensors, most of them are based on piezoresistive (Engel et al 2006; Kane et al 2000;Mei et al 2000;Lomas et al 2004;Kim et al 2006;Wisitsoraat et al 2007; Shan et al 2005) or capacitive (Salo et al 2003;Leineweber et al 2000;Paschen et al 1998;Gray and Fearing 1996;Lee et al 2006; http://pressureprofile.com/products-robotouch) principles, and a few are based on optical (Hellard and Russell 2006) or piezoelectrical transduction (Dahiya et al 2007). Most of these sensors are made using technologies for Micro-ElectroMechanical Systems (MEMS) on silicon (Kane et al 2000;Lomas et al 2004; Salo et al 2003) or on polymers (Engel et al 2006;Kim et al 2006; Lee et al 2006).…”

This paper presents results from a selection of tactile sensors that have been designed and fabricated. These sensors are based on a common approach that consists in placing a sheet of piezoresistive material on the top of a set of electrodes. We use a thin film of conductive polymer as the piezoresistive material. Specifically, a conductive water-based ink of this polymer is deposited by spin coating on a flexible plastic sheet, giving it a smooth, homogeneous and conducting thin film. The main interest in this procedure is that it is cheap and it allows the fabrication of flexible and low cost tactile sensors. In this work we present results from sensors made using two technologies. Firstly, we have used a flexible Printed Circuit Board (PCB) technology to fabricate the set of electrodes and addressing tracks. The result is a simple, flexible tactile sensor. In addition to these sensors on PCB, we have proposed, designed and fabricated sensors with screen printing technology. In this case, the set of electrodes and addressing tracks are made by printing an ink based on silver nanoparticles. The intense characterization provides us insights into the design of these tactile sensors.

Abstract.We present the results of recent friction experiments in which a MEMS-based sensing device is used to measure both the normal and tangential stress fields at the base of a rough elastomer film in frictional contact with smooth, rigid, glass indentors. We consider successively multicontacts under (i) static normal loading by a spherical indentor and (ii) frictional steady sliding conditions against a cylindrical indentor, for an increasing normal load. In both cases, the measured fields are compared to elastic calculations assuming (i) a smooth interface and (ii) Amontons' friction law. In the static case, significant deviations are observed which decrease with increasing load and which vanish when a lubricant is used. In the steady sliding case, Amontons' law reproduces rather satisfactorily the experiments provided that the normal/tangential coupling at the contact interface is taken into account. We discuss the origin of the difference between the Amontons fields and the measured ones, in particular the effect of the finite normal and tangential compliances of the multicontact interface.
