Overview and challenges of energy harvesters for wireless sensor systems

Speaker: Rob van Schaijk

Company/ Institute: Holst Centre / Imec NL

Event: 1st work meeting

Date: 27 May 2009

Abstract:

Today, the batteries that are needed to power wireless autonomous sensor systems limit the possibilities of this emerging technology. Aim is to generate and store power at the micro-scale to improve autonomy and reduce size. Energy harvesters fabricated by micro-system technology can realize this goal. The choice of harvesting principle depends on the application and vibration, thermal, photovoltaic and radiofrequency power conversions are investigated at IMEC/Holst Centre. An overview of our latest results and remaining challenges will be given with the focus on thermal and vibrational energy harvester fabricated with micro-system technology.
