symposium:</FONT></B></H2>
<P><FONT SIZE=2>Polymers have generally played a significant but
passive role in sensor and actuator devices -- as substrates, as
encapsulants, as packaging materials and as aids in processing.
Increasingly there is interest in polymer materials that serve as
active components in solid state devices or as transduction elements
in various sensors and actuators. This symposium, a follow-on to the
successful 1994 symposium of the same name, brings up to date the
increasing attention on polymer materials that are active components
in sensors and actuators and the expanding area of stimulated
controlled release.</FONT></P>

this symposium</FONT></B><FONT COLOR="#808080">:</FONT></H2>
<P><FONT SIZE=2>Covered in this symposium are key issues such as:
polymer material properties (electrical, electrochemical,
electromechanical, and optical) that are appropriate for sensor and
actuator application; polymer and organic thin film morphology and
structure; transduction devices used in sensors (electrodes,
microelectrode arrays, FETs, SAWs, microbalance, and fiber optic
probes); sensor and actuator configurations using polymers such as in
electronic noses, artificial taste and flavor sensors, and artificial
muscles; sensor interrogation methods; and methods and procedures to
confer sensor specificity, enhance actuator response, etc. Symposium
coherence is found in the use of polymers and organic thin films that
are functional parts of systems used as field-responsive components
in various sensor and actuator applications. Such polymers are
capable of directly transmuting one form of potential energy into
another. Examples include the change in chemical potential energy of
an analyte producing a corresponding change in electrical
conductivity, electrode potential, or current in an electrically
conducting polymer; the dimensional change in a redox active polymer
upon oxidation or reduction producing actuation, the change in mass
associated with a specific polymer-analyte binding reaction; or the
change in water content of a field-responsive hydrogel.</FONT></P>
