New solution for future SONAR advantage

Case study from The Technology Partnership (TTP) who pitched their ideas at the CDE Marketplace on 5 February 2015.


The Technology Partnership (TTP) has developed an alternative future sensing solution for SONAR applications, which uses acoustically induced electrical impedance changes in the sea water surrounding a vessel to detect sounds. The Measurement of Electrical Impedance for Detection of Acoustic Signals (MIDAS) system uses simple, low-power, compact sensors resulting in low through-life costs.

TTP has also undertaken a range of projects for CDE within the last 2 years. These have included prototype demonstrations of a short range, secure magnetic wireless communication system and a ‘smart material’ that can passively log temperature of stores and equipment over extended periods.

In business for over 25 years, Cambridgeshire-based TTP employs over 300 scientists, engineers and business innovators. Since its foundation, the engineers and scientists at TTP have played a role in a broad spectrum of sectors including medical and pharmaceutical, wireless communications, micro-devices and sensing systems.

Dr Sam Hyde, Managing Director, TTP says:

CDE seeks novel technologies that solve high-impact, complex development challenges. This fits perfectly with TTP and our capability in rapidly creating and applying new technology to achieve game-changing performance. CDE has been a key bridge, enabling a number of TTP innovations to enter the defence market.
