Autonomous, self-learned, and flying cars are on the cusp of introduction in automotive market. Such developments are stressing the ever growing feature demands on the automotive industry. Contemporary automobile hosts a complex electrical architecture that runs disparate systems. Churning data from hundreds of sensors, transducers, actuators and controlling complex functions, these systems are connected via a circuit which is in total 6-9 km long and weighs between 50-95 Kg. The total weight of just the electrical architecture ranges between 150-200 kg. This has a profound impact on the design, weight, range, carbon emissions and volumetric space available for customer in an automobile. This paper discusses how to change the underlying integration of electronics in a new way so that adverse effects of incremental electronics architecture complexity in the car can be negated. This paper investigates application of printable Electronics and printable hybrid electronics to create new systems. The paper analyses various approach to production and design rules to achieve automotive qualification. How this technology disrupts standards, testing and qualification methodologies. It also discusses results of an experimental application, showing staggering amount of weight saving (70%), 70% saving in bill of materials and processing overhead, and 40% volumetric savings over traditional application. Application’s design, creation rules, testing and failure modes when taken through automotive qualification are also discussed. Few selected key failure modes and their prevention controls like stress, thermal shocks and material delamination are covered. Paper also discusses major design consideration on thermal management. Finally paper discuss the robustness and qualification criterions for automotive in the light of selected application, and the roadmap ahead.


Ashutosh Tomar has been working with various industries in research and development since 1999. He is a PhD student, in Cambridge University under the supervision of Professor Daping Chu, working on pioneering structural electronics research on behalf of Jaguar Land Rover. Jaguar Land Rover has already unveiled use of this technology as a world's first for next-generation in-car personalisation. His previous experience varies from developing embedded systems for telecommunications, to defence systems, to internet security, to automotive electronics. As a keen researcher and inventor for last fourteen years in Jaguar Land Rover research team, he has delivered various new technologies and platforms. He is currently working as Digital and Tech transformation leader in Jaguar Land Rover. With several patents under his belt, his innovations and experience in automotive have been centred around various aspects of automobile e.g., human vision augmentation with computer vision, connected multimedia, Social infotainment, Audio and acoustics, laser-based innovations etc. His key recent achievement is to create automotive qualified structural electronics. This is weight and space saving technology which also offers significant improvements in design (A-surface features), sensing, range, carbon emissions and energy harvesting. He believes this will change the way electronics is packaged in the car in near future
