Special Issue Information

Dear Colleagues,

Sensors and Actuators using polymeric systems, is one of the most promising fields of “smart polymers”, and it is becoming ever more important to associate artificial sensing and actuating systems with living organisms. Testing of some practical applications has now started in industry. The aim of this Special Issue is to develop a basic understanding of the field, its supporting technologies and current applications. Papers addressing a wide range of applications of polymeric sensors and actuators are sought, including but not limited to recent developments in the following areas: humidity, temperature, chemical, mechanical, optical, waveguide, acoustic, electromagnetic, electrochemical, piezoelectric, electrode, electronic nose, switchable devices, biosensors, wearable sensors and actuators among others. Also of interest are methods of fabrication, as well as information on smart textiles, actuators, and the processing of data. Both review articles and original research papers relating to the application of polymeric sensors and actuators are solicited.

Abstract: This paper presents a new scheme for sequentially loading reagents to a detection site to conduct biological assays. The automation of the sequential loading of biological reagents to a detection site is monitored by a lens-less charged couple device (CCD). The fluid handling system employs a custom edge detection algorithm to determine the location of the channel edges. This custom edge detection method outperformed the built in Matlab edge detection functions. A parametric study was performed to determine the effects wavelength, height above a detection site, and voltage of a light emitting diode (LED), would have on the systems performance. A white light emitting diode, a voltage of 2.6V and a height of at least 20 mm above the detection produced the best results. The fluid handling system was also able to work with channels that had different geometric designs and with different types of fluid. This research focuses for the first time, sequentially loading reagents to a detection site using a CCD imager.

Title: Flexible Carbon Nanomaterial/Polymer Composites for High Performance Pressure and Strain Sensors
Authors: O. Kanoun,  C. Müller, A. Benchirouf, C. Gerlach, N. Dinh, A. Al-Hamry, A. Sanli and A. Bouhamed

Abstract: Carbon nanomaterials such as carbon nanotubes (CNTs) and graphene are ideal candidates as fillers in piezoresitive polymer composites due to their outstanding mechanical properties and their broad spectrum of electrical properties. Compared with traditional conductive fillers, CNTs and graphene have unique advantages, i.e. excellent electrical conductivity, which in turn facilitate the formation of conducting networks. Different deposition techniques can be used for realization of large area pressure and strain sensors with high sensitivity and low manufacturing costs such as printing technologies. For instance, by using an elastomer as polymer matrix, the pressure and strain sensitive layers remain mechanically flexible. Such sensors allow both the measurement of planar pressure/strain and the detection of local pressure/strain. In this paper, we discuss the dependence of pressure and strain sensitive layers on different experimental parameters such as composition of the carbon nanomaterial/polymer layer, type of polymer, fabrication process and process parameters. The insights about the relationship between film composition, mechanical deformation and sensor response represents the basis for further improvements of design and fabrication of piezoresistive sensors leading into better sensor performance.

Title: Effect of Angular Velocity on the Morphology Dependent Resonances of Spherical Resonators

Abstract: We carried out an analysis to investigate the morphology dependent optical resonances shift (MDRs) of a rotating spherical resonator. The spinning resonator experiences an elastic deformation due to the centrifugal force acting on it, leading to a shift in its MDRs. Experiments are also carried out to demonstrate the MDR shift of a spinning polydimethylsiloxane PDMS microsphere. The experimental results agree well with the analytical prediction. These studies demonstrated that spinning polymeric resonators may experience sufficient shift in the optical resonances, therefore interfering with its desirable operational design. Also the results show that angular velocity sensors could be designed using this principle.
