Thick film sensors for soil measurements
Thick film sensors for soil measurements
Water content has considerable influence on soil
pore water pressure and shear strength, potentially leading to
failure in earthworks. This research aims to develop novel
sensors (employing Thick-Film electrodes) intended to detect
changes in soil parameters such as resistivity, porosity and
water content and determine if these are indicative of
earthworks instability (potential slope failure). Using Thick
Film electrodes to measure parameters could be a cost effective
method for condition monitoring. The resistivity output of the
sensors and how it relates to the soil water content needs to be
understood, and a framework of working conditions for this
sensing technology needs to be documented. In this study, the
behaviour of the Thick Film cell developed by the University of
Southampton was tested for a particular soil particle size by
simulating heavy rainfall and rising of the water table within a
soil column. Final results show a consistent response from
Thick Film cell for the specific soil sample used, however, the
direction of infiltration has created a very interesting
difference in resistivity readings that need to be further
investigated.

Abstract
Water content has considerable influence on soil
pore water pressure and shear strength, potentially leading to
failure in earthworks. This research aims to develop novel
sensors (employing Thick-Film electrodes) intended to detect
changes in soil parameters such as resistivity, porosity and
water content and determine if these are indicative of
earthworks instability (potential slope failure). Using Thick
Film electrodes to measure parameters could be a cost effective
method for condition monitoring. The resistivity output of the
sensors and how it relates to the soil water content needs to be
understood, and a framework of working conditions for this
sensing technology needs to be documented. In this study, the
behaviour of the Thick Film cell developed by the University of
Southampton was tested for a particular soil particle size by
simulating heavy rainfall and rising of the water table within a
soil column. Final results show a consistent response from
Thick Film cell for the specific soil sample used, however, the
direction of infiltration has created a very interesting
difference in resistivity readings that need to be further
investigated.
