The flexible and printed electronics markets are working towards having speedy, defect-free manufacturing processes. To achieve this, they need new inspection systems that allow live testing and enable real-time quality assurance without stopping production.
Dr Muhamedsalih has helped create a multi-wavelength polarising interferometer (MPI) for in-line surface metrology. It operates at the micro/nano-scale level and can be used for real time inspections of moving surfaces. The interferometer is combined with a software method to handle larger amount of data for surface analysis without direct interaction from the operator.
The system detects and characterises defects. This means that manufacturers will be able to understand what causes faults and take measures to correct them. Importantly, the technology is sufficiently robust to be used on the shop floor.
Hussam is now working to validate the MPI’s performance with world-leading manufacturers and research centres. His innovation is being tested by the UK Catapult National Centre for Printable Electronics – Centre for Process Innovation. His proof of concept system should reach Technology Readiness Level 9 before the end of 2021 and be ready to launch and available to buy soon after.
Analysts have forecast that the global metrology market will grow to over $600 million by 2023 in the traditional manufacturing market. Hussam’s technology also fits into the printed and flexible electronics markets, which are predicted to grow to $77 billion by 2023.
For Dr Muhamedsalih, the Enterprise Fellowship experience has: “allowed me to structure my business model and test it out by intensive direct interaction with industry and potential clients.”
