This study presents the design and fabrication of a flexible tactile sensor printed on a cellulose paper substrate using a carbon black (CB) - filled polyvinyl alcohol (PVA) polymer matrix as ink material. In the design, electrodes are obtained by screen printing of CB/PVA composite on dielectric cellulose paper. The screen-printing method is preferred for fabrication because of its simplicity and low manufacturing cost. The tactile sensor is formed by overlapping two ink-printed sheets. Electrical properties are investigated under compressive and tensile strains. The results indicate that the tactile sensor configuration and materials can be used for piezoresistive, capacitive, and also impedance sensors. The same tactile sensor structure is also examined using a commercial carbon-based ink for performance comparison. The comparative study indicates that CB/PVA ink screen-printed on paper demonstrates superior sensitivity for capacitive sensing with low hysteresis, as well as low response and recovery times. The piezoresistive-sensing properties of CB/PVA on cellulose paper show a gauge factor (GF) of 10.68, which is also very promising when conventional metal strain gauges are considered. CB/PVA screen-printed on cellulose paper features impedance-sensing properties and is also sensitive to the measurement frequency. Therefore, the response type of the sensor can be altered with the frequency.

A tunable 2D rod type Si Photonic Crystal cavity based impact sensing configuration is proposed and numerically analyzed. The cavity is sandwiched by perfect electric conductor (PEC) boundaries in order to provide out-of-plane light confinement. An on-purpose air slot is introduced between the Si rods and top PEC plate moving the light confinement into the slotted region and making the cavity highly responsive to the displacement of top PEC boundary. Optomechanical coupling strength is calculated to be on t...
A sol-gel derived AgCl photochromic coating on glass for SERS chemical sensor application
Volkan, Mürvet; Vo-Dinh, T (Elsevier BV, 2005-05-13)
A new optically translucent material has been prepared that acts as a substrate for surface-enhanced Raman spectroscopy. This material is a silica matrix, synthesized by the sol-gel method and containing in situ precipitated AgCl particles which serve as precursors for nanoparticles of elemental silver. Reduction of AgCl to silver nanoparticles is achieved by UV irradiation. The SERS-active medium was distributed on glass supports (cover glass slips, 0.5 turn thick), hence producing thin, sturdy, and optica...

An amperometric acetylcholine biosensor was prepared by the generation of the conducting polymer poly(4-(2,5-di(thiophen-2-yl)-1H-pyrrol-1-yl)benzenamine) (poly(SNS-NH2)) on graphite electrodes. For pesticide detection, the enzymes acetylcholinesterase (AChE) and choline oxidase (ChO) were co-immobilized onto the conducting polymer poly(SNS-NH2) films using covalent binding technique. Electrochemical polymerization was carried out using a three-electrode cell configuration via cyclic voltammetry. Characteri...

In this study, amperometric biosensing performance of a novel platform utilizing a conducting polymer (CP), multi-walled carbon nanotubes (MWCNTs) and poly(amidoamine) (PAMAM) dendrimer was constructed. In order to fabricate the proposed biosensor, a graphite electrode was modified with poly[9,9-di-(2-ethylhexyl)-fluorenyl-2,7-diyl] end capped with N,N-bis(4-methylphenyl)-4-aniline (PFLA), MWCNTs and PAMAM, respectively. Then, GOx was immobilized onto the modified surface with the help of glutaraldehyde (GA...
