Foreword

This volume contains the proceedings of the Second International Conference on Biomedical Electronics and

Devices (BIODEVICES 2009), organized by the Institute for Systems and Technologies of

Information Control and Communication (INSTICC), technically co-sponsored by the IEEE

Engineering in Medicine and Biology Society (EMB), in cooperation with AAAI and endorsed by

IFMBE.

The purpose of the International Conference on Biomedical Electronics and Devices is to bring together

researchers and practitioners from electronics and mechanical engineering, interested in studying

and using models, equipments and materials inspired from biological systems and/or addressing

biological requirements. Monitoring devices, instrumentation sensors and systems, biorobotics,

micro-nanotechnologies and biomaterials are some of the technologies addressed at this

conference.

BIODEVICES is one of three integrated conferences that are co-located and constitute the

International Joint Conference on Biomedical Engineering Systems and Technologies (BIOSTEC).

The other two component conferences are HEALTHINF (International Conference on Health

Informatics) and BIOSIGNALS (International Conference on Bio-inspired Systems and Signal

Processing).
