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


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.
