Development of a Oxygen Sensor for Marine ... - DTU Nanotech

Chapter 8
Conclusion
The primary goal for this project was to create a first generation oxygen
sensor to compliment the Fish ’n Chip sensor. While a sensor have been
created, it have not been tested, due to problems encountered during the
projects, and as such the primary goal have not been fully fulfilled. However
important steps towards a functioning dissolved oxygen sensor have been
taken.
Possible ways of measuring dissolved oxygen have been investigated, and
a Clark type chosen.
The theory behind the Clark sensor have been detailed, a further study
into membrane materials and electrolytes could allow for improvements, as
some of the potential optimization lies hidden here. Albeit this fall outside
what knowledge of chemistry that I have.
Various designs and the considerations behind them have been described,
and with future results these should provide the basis for improving the
sensor. This should also give a basic idea of what design outlay that is the
most advantageous.
The packaging concept, which proved to be the main problem despite not
being within the focus of this project, have several flaws and will have to be
given some thorough investigation.
The temperature sensor seems to be working within the expected norms,
and while not being revolutionary or even new, it is needed for the Clark
sensor, due to the influence of temperature. An interesting aspect yet to
explore however, is whether the Clark sensor influence it or vice versa.
