Actuation Mechanism
A temperature sensitive
mechanism passively
actuates the valve over the
required temperature range
Capillary Logging
A highly viscous fluid moves at a known rate across a
track of porous media which corresponds to a given
period of time
Capillary Valve + Reservoir
When the valve is actuated
into the correct position, it
enables fluid flow between
the reservoir and the
capillary logging media
Up scaled Demonstrator
The above example was used to
test the actuation mechanism

Future sonar – MIDAS sensor concept
3
CDE Challenge
• Sonar solutions that challenge traditional approaches
• Substantial reductions in size, mass, power
• Increase capability (e.g. higher sensitivity)
TTP Solution - Concept and Benefits
• Novel acoustic sensing technique – MIDAS
• Measures changes in electrical properties of the fluid as
acoustic wave changes its density
• Lightweight, low profile, conformal sensors
• e.g. Sensor arrays on UUS
• Enables new capabilities
• Tomographic mapping of sound field in 3D
• Simple, robust and low cost sensor technology
Progress and Future Exploitation
• Successful lab demo of underpinning concept – TRL2
• Patent application underway
• Next steps
• Further stage of R&D and detailed testing with DSTL
• Investigation of tomographic technique
• Further exploitation
• Seeking sponsors / partners to evolve capability demonstration
