DARPA, on 7 January, announced the Materials for Transduction (MATRIX) programme to develop usable new transductional materials.
Transduction involving the conversion of energy from one form into another is common in many military and space devices, such as communications antennas, thermoelectric generators and electric motors.
Research efforts to develop new transductional materials, however, have largely been limited to laboratory demonstrations and haven’t always resulted in new capabilities or significant size, weight, and power (SWAP) reduction for military devices and systems.
MATRIX will take a systems approach that integrates state-of-the-art materials science, predictive modelling methods, and domain-specific expertise to rapidly validate and optimise new functional architectures that offer transformative defence-related capabilities.
Potential applications include thermoelectrics - energy transfer, thermal management, and refrigeration; multiferroics – enhanced sensors, actuation, micro-power generation, tunable RF and microwave field engineering; and Phase-Change Materials – fast switching and sensor applications.
Jim Gimlett, program manager, DARPA, said: 'Advances in materials have been key to achieving a wide range of critical, defence-related capabilities, but the development of novel, energy-transducing materials has been challenging, particularly in translating materials advances to the device and systems level.'
He added: 'We aim to develop new classes of transductional materials that can be demonstrated directly in applications, and to advance innovative modelling and simulation tools that engineers can use to design systems that take advantage of these new materials. The goal is not just to design materials for use in devices; we envision developing materials that, because of their energy-transforming properties, are effectively devices themselves.'
The initial document focused more on creating the right partnerships and inspiring investment in defence than on any details of how future UK Armed Forces would be armed.
The first stage of developing a new UK Defence Industrial Strategy has highlighted failings in current structures with solutions expected to be proposed in next year’s full strategy.
Romania joined NATO more than two decades ago and the country is vital to the alliance’s geographic reach and its ability to supply Ukraine with weapons.
Although Trump’s geopolitics policy for Europe remains unclear, defence analysts from the US and Europe predict how his incoming administration would attempt to handle critical issues on the continent.
The UK budget announced in Parliament on 30 October was the first by a Labour government in 14 years which has also launched a review into defence procurement programmes.
The Australian government has placed a focus on Guided Weapons and Explosive Ordnance (GWEO) which has included the purchase of additional long-range rocket systems and investments in local production of missiles.
