“…The flow in these systems deviates significantly from the traditional no slip flow because of the microscale dimensions of these devices. MEMS barometers and commercially compatible flexible printed circuit boards are examples for stretchable MEMS [51].…”

An analysis is carried out to investigate the influence of variable thermal conductivity and partial velocity slip on hydromagnetic two-dimensional boundary layer flow of a nanofluid with Cu nanoparticles over a stretching sheet with convective boundary condition. Using similarity transformation, the governing boundary layer equations along with the appropriate boundary conditions are transformed to a set of ordinary differential equations. Employing Runge-kutta fourth-order method along with shooting technique, the resultant system of equations is solved. The influence of various pertinent parameters such as nanofluid volume fraction parameter, the magnetic parameter, radiation parameter, thermal conductivity parameter, velocity slip parameter, Biot number, and suction or injection parameter on the velocity of the flow field and heat transfer characteristics is computed numerically and illustrated graphically. The present results are compared with the existing results for the case of regular fluid and found an excellent agreement.

“…In another development, artificial skin capable of rapid prototyping has been produced. For example, Tenzer et al [22,23] developed a microelectromechanical system (MEMS) embedded tactile sensor that makes it easy to perform rapid typing and showed that it could be applied to artificial skin, while Charalambides and Bergbreiter [24] proposed a method of embedding electronic circuits in soft materials via a simple manufacturing method and developed an artificial skin that can detect slip. While artificial skin developments have often been pursued for use robot tactile sensors, numerous wearable sensors have also been developed for extracting human hand motions and tactile sensory information [25].…”

Rubber artificial skin layer with flexible structure for shape estimation of micro-undulation surfaces

In this paper, we propose a wearable tactile sensor for measuring the shape of micro-undulations on a hard surface. The proposed sensor has two layers. The inner one is a thin rubber layer into which a strain gauge is embedded that is formed around a user's finger. The outer layer is a flexible structure that consists of numerous pins on a flexible sheet. The shape of micro-undulations on an object surface can be measured when a user wearing the sensor traces the surface. The results of an experiment, in which we compare the cases with and without the flexible structure of the sensor, show that our proposed sensor is sufficiently accurate to measure the shape of micro-undulations due to its flexible structure, which contributes significantly to improving its signal-to-noise ratio.

“…However, such solutions typically require bespoke manufacturing for each application and are hence expensive. Recently, low-cost touch sensors based on MEMS barometers have become available [8], [9]. These sensors, coupled with an Arduino micro-controller, allow for simple, configurable touch sensing applications through a USB interface, and are ideal for building touch sensing prototypes.…”

Touch is an important sensory pathway for exploring the world, but most robotic systems either have no sense of touch, use simple binary bump switches, or require expensive custom sensors. In this work we investigate the use of low-cost sensors to acquire more discriminative representations of touch sensations. We show that using two pressure sensors in a 3Dprinted housing we can determine the location of a touch along a one dimensional axis. Furthermore, we can distinguish between different types of touches by the profile of the sensor response.
