Research Unit for IntegratedSensor Systems
Introduction and Overview

Georg Gaderer

Austrian Academy of Sciences
Research Unit for Integrated Sensor Systems• Governmental funded research organization in Austria– Multi-disciplinary– Learned society as expertise background• Some members: Christian Doppler, Erwin Schrödinger, Victor
Hess, Julius Wagner-Jauregg, Konrad Lorenz– Research body organized in institutes (HEPHY), research
units (FISS), commissions (Medieval History Research)• ~1100 Employees (Research Administration)• Current President: Peter Schuster (chemistry)

2Source: ÖAWResearch Unit for Integrated Sensor Systems(Pre) History• Several sensor research projects…
– Capacitive angular rate sensors– Flow sensors• … yielded fundamental insights into design
methodology:• You ought not– start with ASIC design after the transducer concept has
been fixed– think of transducer non-idealities as post-design, purely
ASIC-related issues• Vision:– Integrated Development of Integrated Sensor Systems(~2001)– Research Unit for Integrated Sensor Systems (2004)

Modern Sensor Systems• Local intelligence– Complex, mostly digital multi-level signal processing– Advanced functionality• Sensor fusion– Combination of different (cost efficient) sensors– Compensation of disturbing effects• Networking– Distributed sensor networks, “networked embeddedsystems”– Interconnection to higher-level systems• Need for integrative, system-oriented solutions
