Next Generation Energy-Harvesting Electronics - holistic approach 1763

Lead Research Organisation: Newcastle University
Department Name: Electrical, Electronic & Computer Eng


Whilst the electronics industry is battling with the demand to extend the battery life in the presence of increased functionality through continuing innovation in low power hardware and software, there is a clear opportunity to develop complementary/alternative energy sources for self-powered electronics needed in emerging application areas including mobile digital health, autonomous environmental and industrial monitoring. This is a three-year collaborative research project undertaken by four universities (Bristol, Newcastle, Imperial and Southampton) under three integrated research themes. The project will be carried out in collaboration with five suitably selected industrial partners in line with the research themes and applications: QinetiQ, Zetex, ARM, NXP and Mentor Graphics. Two international experts will also contribute to the project as visiting researchers: Prof. L. Benini, Bologna Uni., and Prof. P. Wright, Berkeley. Our experience, discussions with industry (a recent example is the Batteries Not Included seminar, NXP, Southampton, July 2008, organized by the Electronics Knowledge Transfer Network) and the findings of the recently completed EPSRC-funded Microelectronics Design Grand Challenges Network indicate a consensus that we are entering the era of electronics powered or least augmented, by energy harvesters. Future self-powered applications will require more complex and more compact electronic systems that are intelligent, adaptive and required to perform more computation with less energy. To achieve global optimisation and enhanced functionality, a significant improvement in self-powered electronic design and implementation is required. This can be achieved by adopting an integrated research programme, which takes a holistic design approach to the complex issues surrounding the development of next-generation energy-harvesting systems. In this research programme we propose to take a holistic design approach that will fully consider and exploit the interactions between the micro-generator, power conditioning circutry and computational electronics to make efficient use of the generated energy. The new design methodology will be incorporated into a novel mixed-technology domain modelling, and performance optimization deign toolkit. This design approach is fundamental to ultra energy-efficient design and to the miniaturisation of next-generation wireless electronics. The developed technology, design methods and toolkit will be validated by simulation, experimentation, three ASIC prototypes (adaptive micro-generator, synchronous and asynchronous processors) and a self-powered autonomous wireless sensor node demonstrator for industrial machinery condition monitoring application. To the best of our knowledge, no research programme in Europe or the US has developed a holistic design approach for energy harvesting electronic systems. The proposed three themes are key new areas that require interdisciplinary and inter-institutional collaboration.

Description We developed ways for performing smart computations for energy harvesting powered systems, and variable power supply.
A concept of energy-modulated computing has been developed.
New types of self-timed electronics circuits such as first speed-independent SRAM and reference-free voltage sensors, have been developed and demonstrated.
New concepts of energy-modulation through the causality involved in the use of energy current for computing - this has been reported in the paper in Phil. Trans. of Royal Society A "Energy current and computing".
Exploitation Route These findings can be used to build new generation of electronics for Internet of Things and autonomous systems.

Description The project showed how to design electronics to work in systems powered by energy harvested from the environment. For example, we designed new types of sensors, such as those based on charge to code conversion. They can be used for environment monitoring systems or implantable devices. More knowledge on the holistic approach in designing systems without batteries have been found. It is reported in the key paper in IEEE TC "Real-Power Computing", which talks about the importance of power-compute codesign.
