</FONT></B>The Independently Addressable Microband Electrode
(IAME)-<I>co</I>-Interdigitated Microsensor Electrodes (IMEs) is
an inert, array microelectrode formed from patterned conductors
on an insulating substrate chip. These chips were designed for
the simultaneous interrogation of the electrical,
electrochemical, and optical properties of thin polymeric films
and coatings, for applications in microelectrochemistry, for
electrical/electrochemical impedance spectroscopy, and for
chemical and biological sensor development. With the IAME portion
obtain four-band conductivity measurements of polymer films,
carbon nanotubes, and self-assembled monolayers. With the IME
portion obtain AC Impedance Stereoscopy measurements of the same
material under the same test conditons. The key advantage; both measurements will be performed
on the same substrate chip, for the same material casting, and under the same test conditons. </FONT> </BLOCKQUOTE>
<BLOCKQUOTE class="style3"><FONT FACE="Verdana"><B><FONT COLOR="#00af00">Ø
</FONT></B>Microfabricated from magnetron sputter-deposited gold
or e-gun vapor-deposited platinum, these devices are supplied in
one configuration that includes a four-electrode microband array
(IAME) and a monolithic (M) IME.</FONT></BLOCKQUOTE>
<BLOCKQUOTE class="style3"><FONT FACE="Verdana"><B><FONT COLOR="#00af00">Ø
</FONT></B> The IAME portion comprises four independently
addressable microbands. Each band is 1.0 mm long, 2.0 microns wide
and the 4 bands are each separated by 1.0 micron. The IME portion
comprise 5 fingers per bus. Each finger is 1.0 mm long, 2.0 microns
wide, and the 10 fingers are each separated by 1.0 micron. </FONT> </BLOCKQUOTE>
<BLOCKQUOTE class="style3"><FONT FACE="Verdana"><B><FONT COLOR="#00af00">Ø
</FONT></B>In research and product development, these devices are
widely used for conductimetric, chemoresistive chemical and
biological sensors using electrically conducting
(electroconductive) polymers, for impedance sensors based on
Langmuir-Blodgett thin films, for studying environmental effects
on polymer thin films, and in modern micro-electrochemistry.</FONT></BLOCKQUOTE>
<BLOCKQUOTE class="style3"><FONT FACE="Verdana"><B><FONT COLOR="#00af00">Ø
</FONT></B>Investigate the chemoresistive responses of
transducer-active, polymeric films in the same electrode
configuration, the same test environment, and on the same sample
film. Develop these devices into products where the application
requires a compact, durable and versatile chemical or biological
chemoresistive or electroanalytical sensor of low cost.</FONT></BLOCKQUOTE>
