“…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). These technologies are not orientated to large area devices, and many of them are proposed for applications that demand high spatial resolution and good performance in terms of errors, like MIS (Salo et al 2003).…”

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.

“…Recently, several three-axial MEMS (Micro Electro Mechanical Systems) measuring forces in the three dimensions of space have been developed [7], [8], [9], [10]. Except Beccai et al [11], who report some slip detection results with a tactile device for an artificial hand, very little results have been published on the use of three-axial MEMS force sensor in artificial tactile sensing experiments.…”

Abstract-Recently, several three-axial MEMS-based force sensors have been developed. This kind of force micro sensor is also called tactile sensor in literature for its similarities in size and sensitivity with human mechanoreceptors. Therefore, we believe these three-axial force sensors being able to analyse textures properties while sliding on a surface, as would do a person with his finger. In this paper, we present one of these sensors packaged as an artificial finger, with a hard structure for the bone and a soft rubber for the skin. Preliminary experiments show a good sensitivity of the finger, as its ability to sense the periodic structure of fabrics or to differentiate papers from fabrics calculating a friction coefficient. Its performance for discrimination of different surfaces is then estimated on fine textures of 10 kinds of paper. Supervised classification methods are tested on the data. They lead to an automatic classifier of the 10 papers showing good performances.

“…Examples of such work includes development of triangular [16] and hexagonal [17] tactile skin patches. Kim et al [18] developed such a skin using silicon micro-machining and packing technology (on a flexible substrate), allowing for the detection of normal and shear forces at high resolution. This skin was shown to be able to effectively measure normal force, hardness, slip and touch.…”

New materials and advances in making electronic skin for interactive robots

Flexible electronics has huge potential to bring revolution in robotics and prosthetics as well as to bring about the next big evolution in electronics industry. In robotics and related applications, it is expected to revolutionise the way with which machines interact with humans, real-world objects and the environment. For example, the conformable electronic or tactile skin on robot's body, enabled by advances in flexible electronics, will allow safe robotic interaction during physical contact of robot with various objects. Developing a conformable, bendable and stretchable electronic system requires distributing electronics over large non-planar surfaces and movable components. The current research focus in this direction is marked by the use of novel materials or by the smart engineering of the traditional materials to develop new sensors, electronics on substrates that can be wrapped around curved surfaces. Attempts are being made to achieve flexibility/stretchability in e-skin while retaining a reliable operation. This review provides insight into various materials that have been used in the development of flexible electronics primarily for e-skin applications.
