چکیده

We present electrochemical microactuators which have all the electrodes necessary for the actuation -the working, counter, and reference electrodes -onchip. This is a first step towards an all-polymer system, i.e. a system that does not require a liquid electrolyte. The microactuators' performance was as good as when standard, off-chip counter and reference electrodes were used. Specifically, the speed of actuation was the same. In addition, we obtained a good cyclic voltammogram, although the oxidation and reduction peaks were shifted and some noise was present. Apart from application in an all-polymer system, we will also use these microactuators for studies on the effect of mechanical stimulation of living cells.

Characterization and modeling of PPy bilayer microactuators Part 1. Curvature

Bilayer actuators of gold and polypyrrole doped with dodecylbenzenesulfonate, PPy(DBS), were microfabricated with lengths and thicknesses that varied over two orders of magnitude. The actuators were connected to rigid plates. The curvature of the bilayers was examined as a function of PPy and Au layer thicknesses to enable a determination of the actuation strain and Young’s modulus of the PPy(D...

Interpretation of Electrochemical Noise Signals Arising from Symmetrical and Asymmetrical Electrodes Made of Polypyrrole Coated Mild Steel

This article applies the standard deviation of partial signal (SDPS) plots of electrochemical noise (EN) current signals originating from corrosion events on the symmetrical and asymmetrical electrodes made of uncoated and polypyrrole (PPy)-coated mild steel alloy in 4000 ppm NaCl+1000 ppm NaNO2 solution. Signal recording was performed after 30, 60, 90 min and 24 h from immersion...

Electrochemical Measurements with Interdigitated Array Microelectrodes

ing into widespread use for the trace determination of easily oxidizable and reducible organic and inorganic compounds, because it provides a rather easy procedure for direct and selective detection. Recently, microelectrodes have been receiving attention in this field (1,2). They offer higher sensitivity than macroelectrodes of conventional size, because an electroactive molecule can approach ...

Doped overoxidized polypyrrole microelectrodes as sensors for the detection of dopamine released from cell populations.

A surface modification of interdigitated gold microelectrodes (IDEs) with a doped polypyrrole (PPy) film for detection of dopamine released from populations of differentiated PC12 cells is presented. A thin PPy layer was potentiostatically electropolymerized from an aqueous pyrrole solution onto electrode surfaces. The conducting polymer film was doped during electropolymerization by introducin...

A comparative study on fabrication techniques for on-chip microelectrodes.

This paper presents an experimental study on different microelectrode fabrication techniques, with particular focus on the robustness of the surface insulation towards typical working conditions required in lab-on-a-chip applications. Pt microelectrodes with diameters of 50 μm, 100 μm and 200 μm are patterned on a Si substrate with SiO(2) film. Sputtered SiO(2), low-pressure chemical vapor depo...
