Improved relays for radiation-resistant and high-temperature electronics

Case study from the University of Bristol who pitched their ideas to industry and investors at the CDE Marketplace on 27 April 2016.

Radiation-resistant and high-temperature electronics.

Centre for Defence Enterprise (CDE)-funded research carried out at the University of Bristol has demonstrated more robust and reliable nano-electromechanical relays.

Operation of electronic components in environments with high levels of radiation and high temperatures is very challenging. Nano-electromechanical relays are more radiation resistant and can withstand higher temperatures than existing solid-state technologies, so are the preferred option for these very harsh environments. However, challenges remain around the reliability and functionality of nano-electromechanical relays. The University of Bristol’s work has developed an electrode contact solution that addresses this challenge.

A reliable nano-electromechanical relay-based technology has massive implications for high-temperature, high-radiation environments; both as a switch and as a long-duration/high-integrity data storage device. It promises capabilities beyond that of existing or experimental capability. This technology would have civilian and defence applications, including electronics for aerospace, unmanned systems, nuclear reactors, oil-field equipment and the automotive sector.

Dinesh Pamunuwa, Reader in Microelectronics, Department of Electrical and Electronic Engineering, University of Bristol says:

The funding and support from CDE has allowed us to carry out fundamental research in engineering that has resulted in a ground-breaking solution to a topical problem.
