Speaker: Donald Lupo, Professor, Laboratory for Future Electronics, Tampere University of Technology, Finland
There is a lot of talk about putting electronic sensors “everywhere”, enabled both by miniaturization of classic Si electronics and advances in printed electronics, and the “Internet of Things” is a hot topic. However, sensors everywhere require power everywhere, and billions of small objects fitted with batteries would be a waste disposal nightmare. An alternative is the harvesting of ambient energy, e.g. from light, RF radiation and movement, but some kind of interim storage is needed, and miniature printable , fully non-toxic supercapacitors appear to be a promising alternative. This talk will cover the following topics related to making a viable printed energy harvesting and storage system: - Printed organic Schottky diodes and the role of interfaces in their properties - Printed RF rectifier and harvester circuits based on organic diodes and the need to account for the special properties of organic diodes - Integration of RF harvester and supercaps to run a power-efficient CMOS chip - Harvesting and storage of motion energy using piezoelectric materials and supercapacitors.
Donald Lupo joined the Department of Electronics and Communications Engineering at Tampere University of Technology as professor for electronic materials and the Head of Laboratory for Future Electronics (LFE) in August 2010 after a diverse career in industrial research and development in functional materials for photonics and electronics. He obtained his Ph.D. in physical chemistry at Indiana University- Bloomington, USA in 1984 and spent the next 24 years working in chemical, electronic and display industries, and as an independent consultant, working for and with companies such as Hoechst AG, Sony Europe, NTera, Samsung, UPM Kymmene and Merck. During his industrial career he led groundbreaking work in organic nonlinear optics, polymer LEDs, solid state dye solar cells and paper-like displays. He is author on over 60 publications and inventor on over 40 patents and applications. He serves as an external expert in the OLED and printed electronics fields for the European Commission, is an active member of the Organic Electronics Association roadmap team, speaker of the OE-A Education group and has served on the technical advisory boards of Thin Film Electronics AB, Nano Eprint Ltd., Centre for Process Innovation (CPI) and the EPSRC Centre for Innovative Manufacturing in Large Area Electronics (CIMLAE).
