Our Latest Projects

NHIR: Autonomous X-ray detection

Lightricity is jointly developing with the University of Surrey, Cheyney Design and Development, and the Royal Surrey County Hospital, the first self-powered conformal X-ray detector for dosimetry, imaging, and radiotherapy applications.

SBRI: Monitoring of workers in nuclear environments

Lightricity, Kymira, and NSG have been awarded a phase 1 SBRI contract to develop a unique solution that will better monitor and support nuclear decommissioning operators working in hazardous environments.

SPECTRAIL project for UK Network Rail

SPECTRAIL is an IoT sensing platform that enables truly intelligent infrastructure. It is simple, low cost, fast to fit, maintenance-free, and able to sense at a majority of locations, yet, through its novel architecture, remains very flexible to local requirements. Jointly developed by AP Sensing, Pyreos, CSA Catapult, and Lightricity, the platform will allow the infrastructure custodian the ability to collect data at sites previously inaccessible to power or connectivity, or at those deemed too high cost. The benefits to the infrastructure owner arise from a new ease in collecting targeted and actionable asset condition knowledge, enabling a predict-and-prevent maintenance strategy across many asset types – benefits which can be passed directly to rail users.

Lightricity advances Deployable Solar Power for Small Satellites

Lightricity has completed a £1.1 million UK Space Agency-funded project with AVS UK Ltd and the University of Leicester to develop a roll-out flexible solar blanket for small satellites. The prototype combines ultra-thin multi-junction solar cells with a compact deployment mechanism, helping increase power density, extend mission life, and support more capable satellite payloads.
