TRANSDUCER INTERFACE INSTRUMENTATION ASICs PROPOSED CLUSTER MEETING IN
STOCKHOLM

In our laboratory we have a research activity focused on the development of a
chip potentiostat for hybrid interface with chemo- and bio-sensors. The first
chips have been fabricated and are now under test with an amperometric
biosensor.

In collaboration with MSTB LTD, propose to organise an impromtu cluster meeting
(at Transducers'95 / Eurosensors XI in Stockholm) on similar instrumentation
ASIC developments. We envisage a short and informal meeting to establish
personal contacts, exchange notes and provide an opportunity to acquire an
overview on the current status of this focused topic area. The meeting will be
arranged so as not to distract or intefere with the main conference proceedings
and according to the response to this call.

Please send a brief reply message if you work in this field and wish to attend.
We will collate abstract contributions from industrial and academic
practitioners working in this field and make copies available at the meeting.
Please send your brief abstract in ASCII format by e-mail. Our contribution
below may provide a model. Abstracts will be collated and made available as an
ftp file from our internet W3 server for wider dissemination to the scientific
community. Please only include non-confidential data.

Please e-mail Tarek Jomaa and David Barrow on SABTJ@cf.ac.uk"> as soon as
possible.

Example Abstract.

Title: VLSI Chip Potentiostat for Chemical Sensors.
